Title: Mk2 Digi2 9a
Post by: RevHappy on September 14, 2012, 12:03:11 AM
Hey guys
In need of some Tech advice
Now i know a couple of you out there have done this and it may be a walk in the park.

I will be getting underway with my 9a conversion in the coming weeks and have been studying like crazy as i am a bit dawnted by it. From my understanding the digi2 system will run it just fine (not perfect but fine) my 8v g/box will fit and everything else should be a plug and play. There are just a few things, online most speak of changing the fuel rail to a aftermarket one??? Also i read ages ago that a saab or volvo dizzy was needed, yet now when i read online it says the 9a one will sufice. Any light to be shed on these? Also how necessary is the oil cooler?

Cheers for your help in advance.

I am currently running a 9A on digi with KR head and cams.
It is slow. Runs fine, idles fine, runs slow.
I have driven another Mk2 of a vask owner with ABF and original DIG 3.2 injection., Difference was almost night and day.
My conclusion, contrary to what you read on the net re digi 2 conversions,  is although you can get it to run fine on DIGI 2, it will be considerably down on power it should potentially have.
I am changing to KR K-jet in the next couple of weeks so will post the difference.

Dont use digi and dont use a saab dizzy, just use the 9a kjet and ecu, its only a few wires that need hooking up

He will have to fit the whole K-jet fuel pump and fuel lines and everything tho as his car is obviously a digi mk2.
Is this what you are doing JohnP?
Do you have the whole 9a fuel system and ecu and wiring loom manik?

I actually think you wanted to be called gtimaniac did you?

JohnP is your digi 9A with a standard ECU or have you got one of the plug in chips that you can buy that re-maps the fuelling?

I have tried standard but currently have a "digifast" chip.
I was going to look at a chip that Nuespeed sell specifically for the 9A conversion,  but for the cost I am changing over to KR K-jet.
I have plots that show this outperforms any other system, chipped or KE motronic, even an ABF with KR K-jet will outperform  the ABF with standard Digi 3.2.
My previous 9A conversion ran Ke-motronic (std B3 9A Passat injection) and this definetly went better than the DIGI2  set up I now have.
My advice to gtimanik is to run the 9A Ke-motronic if he has it,  or IF, big if,  he can get his hands on a complete KR K-jet system, to do that.

I agree, if he has this system, use it. My previous 9A conversion ran the KE-motronic and ran much much better as far as acceleration and top end were concerned.

It may be so that a KR K-jet ABF could be very slightly faster but the system has other weaknesses and you economy will not be as good as if you keep your ABF on the digi 3.2.

This however has little to do with what maniac needs to know.

It is a shame so many people buy the engines without getting all the other stuff they need.
It would seem that the fitting of a 9a into a already K-jet golf is the best cheapest easiest way to go.
Or buy a complete ABF engine with loom and ecu and fit to either a digi or K-jet golf.

I still have a complete ABF engine with loom and ecu I would sell. $1000ono
If it does not sell it will find its way into my new mk2 golf one day.

BB, the 8V Kjet is not the same as 16V K-jet. The fuel distributor is different, the cone shape is different so the fueling is not the same.
Also the 16V k jet has a seperate control unit for the ignition map. I do not think standard 8v k-jet on a 16V would be much better than 8v digi 2.
And I am circumspect about the Saab dizzy after your story some time ago re the targa guy running this set up and his engine being destroyed from detonation.
K-jet is just as economical as digi 2 from my experince. Digi 2 is all about emissions.
Title: Re: Mk2 Digi2 9a
Post by: BB on September 14, 2012, 04:12:46 PM
True true but then you always hear stories that a k-jet unit can run up to 300hp.
They must be BS stories.

I guess it would be easier to fit the 9a k-jet fuel unit to a 8v k-jet golf tho as you don't have to do the fuel pump, and the bits would pretty much swap out.
Add the ignition ECU and broom a Passat powered golf.

Kr k-jet units are quite rare.......mostly found in 16v powered golfs already >:D

I like the KR motor better than the 9a I think.

Post by: cpncrash on September 14, 2012, 07:52:08 PM
Agree with Basil and JohnP on this one (Tho I have never been in a digi powered 16v)

I first ran my 9a on the Passat K Jet (Motronic) and it ran pretty good apart from some idle issues

Changed the head to ported with KR cams - Got better

Then changed to KR Injection from a 16v Golf and it was a wee bit better again. I feel it goes ok but have never driven anything to compare against.

I had an auto 9a passat once and it went really hard!! wish I had kept the setup, it runs well when its all running well...... haha

And Agree with BB that KR engine are great they just have a nice pull to them over the whole range. I really liked my 16v GTI golf.

GTimanik

I will probably still have a full B3 passat injection system sitting in the garage (I cannot confirm this until I have a decent look thru all the bits from over the years)

If your interested let me know

Running it on digi might be a good way to get it up and running quickly tho I'm not sure how much work would be involved.

I bought the engine off Deedub(dave) and he has just given me the motor so i had always planned to run it on digi. I would like to run it on digi just to get it going. Nothing is permanent.

What are peoples experience with the fuel rail? what one do i need?

Do i just run the 9a dizzy?

And the oil cooler question???

If you don't have the ignition ecu and loom for the 16v 9a dizzy you have an issue.
The 9a dizzy has possibly only one cut out like the ABF I'm not sure, but even if it has 4 it has no advance weights or vacume.
That's where a Saab dizzy with vacume and weights and 4 cut outs comes into it.

Does the digi rail not fit at all? What rail did you use JohnP?

What oil cooler question?

The 9a dizzy is a 4 window and is locked ie no vacuum or weights, the saab dizzy is no good as it doest have the correct ign advance curve.

Do you have all the bits you need for the 9a? If you dont I have a couple of spare fuel distributors, ecus, injectors and lines

You can make your own fuel rail, or buy one off the net from the states. A couple of places do them.
BB can tell you about a Niissan fuel rail you can use.
Yes you use the 9A dizzy, modify your existing DIGI2 loom, you do not need any other loom.
If I were you I would buy the 16V 2.0l DIGI 2 chip from Nuespeed. Would probably then run fine.

Post by: BB on September 15, 2012, 09:59:59 AM
Oh yea there was a golf 9a we fixed that had a Nissan sr20 fuel rail.
And yes If your car is a digi which it is you can just use the 9a dizzy with the ECU you have already.
What mods do you need to do to the loom tho John?
And then once you have it going then get the Neuspeed chip or you will be down on power as the 8v digi system really is about efficency and does not really gas it enough.

Its the K-jets that need the saab dizzy, which may not have exactly the right curves but it is for a 2l motor so will run it fine. The car that detonated was being driven extremely hard on a Targa and other things went wrong as well that added to the piston melt down.

I think the 9a has a oil cooler on the oil filter and should have the hoses all there so just leave it as it is.

Loom mods are essentially lengthening to get to the various sensors and fuel injectors. Its all very easy once you have a fuel rail.
You will need to change out the injector cups in the inlet manifold as they are not the same. Order new Digifant 2 injectors from the dealer, they a cheap enough, I have never had any success getting the DIGI2 plastic ones out of an 8V manifold.

Conversion fuelrails are around stateside ,read a full article on it and they only come alive with the chip,standard Diji 2 has and an ecu with tame ignition setting and fuel mapping and the engine doe's run lean,the chip I'am running was really noticeable in my otherwise stock 89 when I had that.
I know that the conversion I read about produced good power for the owner,PM me and I will try and find the link its really well done.
The chip I'am running came from a guy in the UK ,he can custom map according to mods done as all his work is down using a rolling road.
My chips makes the bottom end smoother from idle up to 3000 and then it really kicks in.

Title: Re: Mk2 Digi2 9a
Post by: BB on September 15, 2012, 08:47:16 PM
Standard Sr20.

All this 16v talk got me going so I ripped out my 8v digi motor and sub frame from the mk2 and gona get on with fitting my ABF.
Will have to pull my dash again but that's so easy on a mk2. Gona fit the mk3 fusebox and front loom complete. But not airbags or ABS.
Title: Re: Mk2 Digi2 9a
Post by: watercooled on September 15, 2012, 10:00:29 PM
The reason for chipping is that the flow of the 16v way exceeds any thing you can do to a 8v head period,a good set-up 8v chip will help and you can adjust the stock diji afm to help or go for a 2e afm(worked for me)
Sorry BB but the Saab dizzy won't cut the mustard,as mentioned there are ignition curve problems ,the loom and wiring is up to you and no differant to what i've just done,like anything'' if you have done it its easy ''.
Make a wise decision regarding ce 1 and ce2 loom for your car ,getting a ce1 to work on diji 2 is less work than a loom change,but will make it easier if you don't have much wiring experience.
Basically (sounds easy ;)) presuming your car is k-jet?,if you retain ce1 loom you need to repower the fuel pump,use the warm up regulator feed for that,you need to wire in a basic relay to power your ecu this feeds off the "key on" side of the fuseboard,earth to body,relay feed output 87 to wiring under the scuttle near the heater inlet.
There are issues with other stuff like temp sensor repositioning and extensions to the stock diji ecu loom ,don't be put off,besides there too many digi haters on here :laugh: :laugh: :laugh:

Talked to a mate today and hes going to get hold of a sr20 fuel rail for me. i know i need to extend the injector wires but will be using the 9a dizzy as it says online to use it with the digi2 8v hall sender so will give that a go.
Will start not this week, am coming up to Auckland for 3 days  (Tue,Wed,Thur) so once im back in chch i will start on the Friday night/Saturday.

Out of interest....JohnP are you in Auckland? When im in auck next week could i come have a look at your set up? or does anyone want to come have a beer at a pub and talk some s*** about the conversion, wouldnt mind meeting some of the almighty wise ones of the north.

Yes I am in Auckland. You can give me a call when you are here. P-mail sent with my contact.
You do not need to change the hall sender in the dizzy.
All the hall devices themselves are the same, 8V, 16V.

Yes your digi dizzy plug will plug straight into the 9a dizzy and work.

The Saab dizzy is used for k-jet conversions and they work, Andy balls ran his 9a on one as have many others. They come from a similar 2l motor and are fine for most driving.
Yes it is better to use the 9a ignition ecu and k-jet system but as with Will many only get the motor.

But it is simple, fit the 9a motor with the 9a dizzy. Fit the SR20 rail and plug all your existing wiring to dizzy and change the plug to suit the new rail.
The car will now run but be gutless.
Get a spare Digi ECU (I have one) send it to get a proper 9a conversion chip, plug back in and whammo your fueling and spark will be just right to get the best from the new motor.

Will your welcome to come visit me and get a spare digi ECU, we will get JohnP over and go down to Joys Cafe for a bite to eat.

S*** mate, cheers. Thats everything i was asking for. As for the spark and fueling tuning. Can this be done by a chip or is it best to send a whole ecu. And is it a job for specialists? ie platinum? or could Volksworld in chch give it a go?

S*** mate, cheers. Thats everything i was asking for. As for the spark and fueling tuning. Can this be done by a chip or is it best to send a whole ecu. And is it a job for specialists? ie platinum? or could Volksworld in chch give it a go?

Do what I p-mailed you. It will then cost you FA.

It sounds like there are special 9a chips for the digi2 ECU you will have to shop around and ask and they will cost a bit and need to be put in by somebody who knows what they are doing.

Or do what JohnP has said.....which is what?

What stage are you @ with the diji conversion?did you check the 16v digi FAQ on Vortex?.
I reckon with the right chip it will work,also release your AFM spring 3 notches and that works good along with the chip also.

No mate you need an adaptor to go in the fuel rail this kits have optional bits for sweet fa as far as you need,the main bit you  you need is not in this kit.
Be aware the hose supplied isn't rated for s#ht it cracks after a very short time ,if you value your car NEVER use it.
Title: Re: Mk2 Digi2 9a
Post by: deedub on December 15, 2012, 09:45:03 PM
Hmmm looks to me like it would work. I see no reason why it wouldn't. If you're worried about the fuel hoses, just buy some quality stuff from BNT or somesuch, but the FPR itself should work. If I remember right the BBM rail is 8mm, it is designed to be used with an aftermarket FPR as VW ones sit in the fuel rail itself.

Hit up kiwi, his mate ... Arousn I think his vask name is - supplies aftermarket parts like FPRs and might be able to help.

The FPR is fine on its own,only said what I did cause I presumed your fuel rail took a standard fpr ,I made a fitting when I bought the same kit,I'am fussy when it comes to hose for obvious reasons

How did u make the adapter? Cause the fpr sits inside the adapter so it would have to be engineered to a mm
Title: Re: Mk2 Digi2 9a
Post by: watercooled on December 16, 2012, 12:01:07 PM
Yea I did and the tolerances are close,but that was for a standard fuel rail, any half decent engineering place could make on for your aftermarket rail.
OK had a look on the BBM site did you buy the billet alloy one ? if so can't you take the end fitting off (rh side) and put a barbed hose tail on there to your fpr ? you need to set up to to 3.5 bar from memory ( you probably know that),also the instuctions are a bit dodgy atleast they were with mine best to Google it,cheers.

Ok. im in real need for someones help here! The golf is playing with me now. Went out to the garage today to give it a go at cranking it over. battery is flat so put a jump pack on. with the jump pack on the + and - terminals of the battery the interior light comes on and the interior fan switchs on and stays on ( it didnt used to do this ) but it wont crank over :(. With the -ve jumper lead on the intake manifold bolt and +ve on the battery it will crank the motor as it should but wont start.....? Why?

Once i got the motor cranking it wouldnt fire up.............and the isv isnt buzzing away like it usually does. I pulled the fuel rail out to check the injectors because i am skeptical about the plug that i have used (blk/yel and brwn/yel) and  nothing. definitely fuel pressure as the gauge is reading 6bar. So i hooked up a hot wire to see if the injectors actually work or not and they open and close as they should on the hot wire. ARGHHHH

Can someone please please please help me. Im sure someone has been there done that before.

Thanks
Will

Post by: BB on January 16, 2013, 08:41:47 AM
Hi Will, I don't have a mk2 digi to check anymore sorry tho later I will look at my Bentley manual for the wire colours to the Rail.
I am sure tho that if you have two plugs that could fit you should just try the both of them separately?
Also just charge your battery and hope that cures the odd electrics. Make sure all your earths are clean and good as this is the usual reason things go odd as they try to find paths to earth.

Then with the battery good check for spark if yes then spray engine start, if it runs then simply figure out how to power the fuel rail (must be one of the plug surely?) and you should be away!

Post by: RevHappy on January 16, 2013, 10:24:34 AM
Tried to charge the battery all yesterday but I think it's buggered aol will need a new 1. Had limited tools last night (10mm spanner and a tiny pair of vice grips) so will take more home and check spark. The coil is sparking cause that got me really good

I'd check the distributor hall sender and associated wiring, on digis it is the only signal to the ecu that the engine is turning over.

Full power on what? Should be constant 12V on the live to the fuel rail, as they have pulsed earths. But if the ECU isn't getting a signal from the hall sender, it doesn't tell the injectors to squirt. So worth a look, along with the fuel rail wiring.

I'm running megasquirt so possibly not relevant but thought i would post anyway in case it helps. I found that the isv in my car did nothing while my hall sender was bung. The moment i replaced the hall sender the isv buzzed away if i turned the engine over (or for that matter turned the dizzy by hand) not sure if yours just did it while the ignition power was on or when cranking though.

It is true that the digi has a pulsed earth (well Im not going to doubt Deedub ;)) but unlike most EFI the early digi does not pulse each individual injector, they all spray at the same time like a CIS  K-jet system.
Also the idle valves are a solenoid, they should click open with power and click closed with the power off, they should not buzz. They buzz when they are crapping out as far as I know.
On the mk2 digis the ISV is as it says, an Idle Stabilization Valve. They are triggered not by the idle switch on the throttle body but by low revs. They open a air way that bypasses the closed butterfly and gets the revs back up, Ie they stop it stalling.

On the later mk3 gti ABFs the solenoid is a Idle Valve. On lift off the butterfly closes completely and hits the idle switch which opens the IV and allows air past the butterfly allowing the car to idle.
If you ask JohnP he will tell you how you can test the Hall....................cause I always forget tho I think its just put power to it and a earth and read the middle prong with a multimeterwhen turning it by hand, obviously with it removed from the car.

Got it all sorted out last night. That is how I got it started. The injector wires had the polarity backwards so when switched the injectors were going full tit on start up. Definitely got spark. Does this mean the hall sender is ok Quattro? Am devoting a full afternoon and night to it tomorrow. Reason why I didn't get it running and leave it running was I thought the injectors would make it rev until it blew and the earth I had was smoking. Got one from the head to the coil. Putting 2 more proper earth straps on from a mate that works a FH so pretty sure they will be beefy

Yup sounds like your hall sender is fine. Make sure your gearbox earth is good! If the one at the head is smoking while cranking I would check the big gearbox one as well.

Be careful if you think your injectors are on full, apart from filling the sump with fuel you can also hydraulic the motor too if you crank it for too long.

My guess is you do not have a proper battery to body to motor earth. The big butty cable.
You may have earthed thru the ECU when cranking and fooked the ECU, hence the injectors are on full tit.
The polarity to the injectors does not really matter as they are not sequentially driven and are just coils.

 Pull the plugs out and then fit them to the leads and lay the plugs so they can earth to the head.
Then crank it.
If it sprays fuel out the plug holes (plugs can ignite this for a bit of action!) you have a blown ecu.

Mmmm if your earth strap was smoking it does seem fairly likely that your ecu is toast.

As has been stated before, if your earths aren't totally sorted the starter earths through the ECU and burns out part of the ECU board, which causes the injectors to get stuck on full cycle. Seems this happens quite a lot when clutches get changed and earths get missed out.

I think I have an ECU somewhere you can try if it turns out it has been cooked.

You can do what Jem suggests just to see if the injectors are on going full tit, it's best to take the plugs out so it's easy to tell that there's heaps of fuel going in and also will prevent the motor killing itself by trying to compress all the fuel that has been dumped in the cylinders. Sounds a bit dangerous though!  And you have nice paint on the motor  :-[  Or you could unplug the injector plug and get an auto scope between the fuel rail supply wires to see what duty cycle the injectors are on if you have a mate who is a sparky. A friend of mine had one and it was very handy for this kind of troubleshooting.

Its not dangerous. its just if you cant find a place to earth the plug away from the fuel coming out the spark holes it can ignite with a quick flash, it won't hurt anything.
The reason is if you want to crank a car with the plugs out you do really need to earth the leads so the spark can escape or you can damage more stuff.
You could do this by adding a test wire from the leads to the block rather than the sparking plugs but hey I enjoy making flames >:D

People fry the ECUs when they do the clutch as you have to move the engine so much to swivel and remove the gearbox you need to undo the earth strap to coil and they forget to put it back on.
Its a real drag.
Do as I say remove all the earth leads and sand clean and reattach. There is one from battery to the battery tray then down to gearbox.
Then there is the small rocker to coil.
This is enough if they are all good, but fitting more can't hurt.
I have a earthing lead set that came off a MK3 gti I am going to fit to my mk2 abf......just cause I have it and its a nice bit of kit.

Thanks to Andrew, Craig, and Dave I got the engine started and running. 3 ecus later. Only problem is it won't hold a idle. Is that cause of the signal from the temp sensor isn't good for the ecu? Or isv not working? Or wrong ecu? The ecu numbers match except for the last two letters. Does that matter? Going to try the ecu chip in the working ecu to see if that will work.

Don't much around with the ecu yet.
And the rocker earth should go to one of the coil bolts not just the scuttle I think is best in case the coil is not attached to the scuttle well.

If it starts and revs and drives ok then your idle will be because the idle switch is not working or the ISV is dirty and part open or you have the timing a bit out or something I doubt its the actual ecu.
But good going.
Title: Re: Mk2 Digi2 9a
Post by: RevHappy on January 19, 2013, 09:02:45 PM
The rocker to coil earth has always been on there. I just added another for security onto the rocker. It starts and revs fine but the rev is ambit delayed. I'll upload a vid soonish so ya can see it. I think it's the isv tbh. So even though the letters on the ecu don't match it should be ok? The new one says TAN where as the old one didn't

That's craig's ecu? It shouldn't matter. Yo could try my one as well anyway, but I am pretty sure they will be near identical. I think the ISV setup on a digi 9A is a little bit tricky, might pay to have a read through the US forums about how people have got them idling well.

You mention that you fitted an earth from box to chassis - from memory there should be a box to battery one? That might be a good one to have just in case, to give the starter motor a really easy earth path.

Good work that you have it running!  8) 8)

Only issue is it doesn't fit over the mani of a 16v.
True mate forgot about the 16v,the brace I had fitted with the crappy GX motor and stuffed mounts never came close to touching the motor,did the 3a conversion and it fouled real bad on the TB ,a quick bend up on the alloy centre section and all was good and it still cleared the bonnet.
Will, my boy has a front offset brace that I had on my old 4 door that type would clear your manifold.

I am bidding on a 16v lip on tm for this but just noticed that it is pick up only. Does someone feel helpful enough to pick it up for me and send down to chch. I will pay for the item before it is picked up. And u will also be paid for your time, gas, and of course shipping

I think it's something like a 20% change in power and you're supposed to get a cert. Not sure though, because I can't see it ever being a problem.

I'm not getting one for my ABF.
Its such a toss off anyway certing when its the driver and or any mechanical thing like leaving a wheel nut loose which can happen any time that will cause an issue.
They just take your money for crap.

just plead ignorance and state you got the car this way and engine is factory as far as yo know.
and the steelies are not widened but were built this wide.
i got cert but only to rectify green sticker,but is for works burger-seats,susp,engine,exhaust,etc
it feels like a protection against dick head cops but pricey at $650

Alrighty car has been going good up until saturday. Starts to miss fire on idle and cruising once up to about 85-90? but not on accel. There was also water in the oil catch can. Im pretty confident its the head gasket but after a little reassurance before I rip it off. If I do then a p+p and abf cams will get thrown in too

How much water in the oil catch can?

I wouldn't jump to the conclusion of headgasket. It's just getting colder and wetter in chch, my kombi would get water in the catch can and even foamy oil - and it's aircooled! It was to do with the engine not running the best rather than headgasket. If you have oil in the water or bubbles coming up through the header tank, or coolant hoses pressurising, then I'd be more certain it is a headgasket.

Yeah, the mayo gets on the cap of every car I've owned as soon as the weather gets a bit cold and wet, burns off after a bit of a run.

Do you get the bubbling in the coolant?

Havnt noticed any bubbling. But it does get a miss when warmed up.
Was about 150-200mls of water in catch can

That's a lot of water. If it was a big head gasket failure I would have thought the hoses would be well blown up. If it's just a water to oil failure, it won't be what's causing the miss anyway.

They have an oil cooler standard. Near the oil filter.

The motor was standard, never been split, ran like a champ. 140kms I think.

I guess if water is getting flicked up onto the catch can breather, that could be where the water is coming from.

200mls, you'd notice that as a drop in the coolant level. Fill it up and keep an eye on it. I'm pretty confident you don't have a headgasket issue though.

So coil leads or dizi then? Will chuck another coil on this weekend and see if that fixs the miss

Alright. Bit of a update. Got some abf cams from ranton. Still havnt chucked them in. Finally bought myself a daily. And got my golf into my workshop. Car has been stripped for 2 weeks. Got alot of panel beating done. Front guards, doors, tail door. And roof. All glass removed. And colour decided. Got rear guards, front valence and bonnet left. Then primer, paint and reassemble. Also got my coilovers delivered yesterday. Cant wait to chuck them in and the cams. So stoked and excited to get it finished and show it off!

Also when the car is hot and I turn it off to get gas or to nip into a shop then go  to restart it I get maybe one or two cranks, very slow cranks like the starter is having trouble to start then sometimes it will burst into life. Other times will just kill the battery and will need a jump. Thinking bad earth, too weaker battery or starter not upto task. Am using the 1.8 8v starter. Have inquired about a 1040cca battery to try and muscle away the issue. But scared of buying a super expensive battery and killing that too.

13V would be about right. If you are sure the battery is ok, then its probably the alternator- sounds like it is not charging the battery enough.

So get the alternator rebrushed? Have access to a mk3 one.

That might be enough, depends how far gone it is. Personally I would just replace the alt.

Alrighty. Has anybody got a mk2 box lying around? Or better yet a 02a from a mk3 gti? Rather interested in the hydro clutch idea

And all appropriate hardware? Thinking of cutting and welding the pedal, cause finding a corrado or b3 passat one is too hard.

JohnP had a pedal box for sale about 2 or 3 weeks ago

I have everything else.

I even have a Spare LSD'd 02A handy.

Been enjoying the car ever since putting in the gearbox. Has been running like a trooper and is still always getting looks.
