MK4 R32 - ECU ReMap
« on: October 25, 2017, 11:51:49 am »
Hi Guys,

I'm very new here and looking at getting my R32's ECU remapped. I am sure some people here have had it done, can anyone point me in the right direction to where is best? I'm a bit confused as to where to go as prices seem to range from $750 to $1500. I am based in Auckland.

Cheers!!

Have a chat with GLIDN on this forum. He's done a few of them in his time. He's based on Brown's Bay

Complete waste of money on a non turbo car, better to spend money on other upgrades.

ECU remap on a N/A car might not give you big numbers to brag about, but it will give you a better torque curve if done right. IMO that makes the car much better to drive.

The gain will be soo small you will barely feel it. Many opinions out there on this subject this is just mine.
I'd never ever waste 750-1500 on remapping an N/A car.

I've "heard" the R32's are NOT particularly responsive to remapping anyway, some minor gains but hardly worth it.

They actually have a really good low end torque curve, but they are NOT a performance engine, they're a bit of a clunker - 184kw from 3.2L is pretty mediocre, even in their day.

Cams and a map is a bit different, but that's getting into big dollars already.

Save up for a supercharger  >:D   I'm going to tell my Mrs that ours is broken and I need a new one  ;D

I guess my experience with a NA 3.0 Subaru was a bit different. A few reasons for that though. 1. The factory ECU map is terrible and leaves a big hole in the torque delivery.  2. The remap only cost $400, so not quite in VAG territory for prices.
In the end it cost me less then $1000 for headers, and ECU remap and got a useful 30something kw gain from it and a torque curve so flat it looked like a table.

As I have tuned many mk4 R32 golfs.

I have seen as much as 20kw @ wheels increase in low RPM range 2000-4500rpm range.
There after it mellows out to 10-15kw @ the wheels increase. (yes I have dyno graphs)

So in short it's most certainly not a waste of time.
An entire new experience and the way the R32 should have been from the start.

To finish off, I have seen mk4 R32 golfs into the mid 13 second quarter mile bracket simply from a retune.

Please post the dyno graphs, everyone always talks optimistic numbers but no one ever backs it up.
And please spare me with overseas graphs, NZ dyno plots before and after.

Oh common Hennie, I know you sell this stuff but really - a 20kw gain at the wheels at low RPM on a NA engine? The car is probably only making around 100kw at those RPMs and you're saying you can gain 20%. Where is that 20% extra air coming from to make that power?

We do remaps down here in Queenstown and I get asked almost weekly to do R32's. I always talk the customer out of it with the simple statement of "I wouldn't pay for it personally, therefore I wouldn't advise it either". But then, a salesman I am not.

There is a VERY slight difference in response but that is largely due to throttle mapping.  We have done the odd one that customer has insisted on or has wanted cat delete so needed it anyway and they say they "think" it feels better..... placebo in my eyes.

I will await the barrage of "your remaps must not be great then"  ;D ;D ;D ;D
Too much power is almost enough.

Phil, some how you may incorrect idea of what I do?
Unless it's physically worth it? I will not tune any car. Which is what I advise anyone I interact with.

Everyone works hard for their money and I understand this.
If I'm not willing to do something to my own car? I will most certainly not do it on anyone else's car.

To be fair I send away approx. 40% of clients due to their car not even being in sound condition before any mods are to be carried out.
I'd rather save anyone from themselves so to speak then take a dime from them, full well knowing the outcome will not be what it should be.

Do Remember thou... I owned my own Mk4 R32 for almost 2 years doing R&D from intakes, suspension, tuning and haldex controllers.
That way I know if something is actually a worthwhile investment/upgrade or not. This is why I advise against any intake mods on these. As they do not gain any note worthy power on this particular platform.

The power above quoted are specific to Mk4 R32.

The Mk5 typically only sees a 10-15kw increase. But again, that's not that big numbers?
How is this fact? The mk5 R32 achieving 0-100kph in 6.7 seconds now manages a very impressive 5.5 seconds 0-100kph.
That's most certainly noticeable. No matter which way you look at it?

I'll happily post a dyno graph. Once I have made yet another online account to host photo's with.

To claim 20kw gain at 2000-4500 rpm on any NA car tells me you clearly do not understand how an NA engine works.
Let's see the dyno graphs as you claim, physically not possible without cams, raising rpm etc.

hi Samdaynz,

I see its your first post so welcome to the Klub.

Are you daily driving this car?

Reason I ask is I have dabbled a little bit with modifying a Normal aspirated ( no turbo or supercharger ) car and I found to get any decent gains you need to change the camshafts and move the power band higher in the rev range and then provide the fuel to balance the air fuel ratio. This way you will make some gains in power, but and its a big but, you will sacrifice torque down low as you have changed the camshaft to do this and for a daily driver, torque is what you really want. In my opinion if you tuned your engine without any other mods I doubt you would notice any differences worth justifying the cost.

If its a track car, torque is still your friend but the sing of a 6 cylinder at high rpm with ITBS is the best sensation on this planet ( bar a few exceptions )

Cheers,
