JaseNZ,
if you're up in Auckland? if not, no matter can remotely tune your vehicle as well
I have built and tuned plenty golf R's, even built them in other regions in NZ as well.
Flew down to assist them, happy to explain anything and everything you need to know.
As others mentioned, can provide Unitronic software, I too can custom tune them as well.
So far, one of my custom tune customers hit a 12.14 sunday at meremere. Only Downpipe, stage 2 ECU and Stage 2 DSG.
Which I know we can do more, once we start replacing the limiting factors.
So far everyone I have seen offer custom dyno tuning, have for the most part done the exact same process as simply buying a file, flashing and sending you on your way.
What the most have forgotten unfortunately, is there is so much more information required other than a power run and AFR graph, which I'm afraid only provides approx. 15-20% of the overall picture a car is providing
Recently I had to retune a golf R which was "custom dyno tuned", had been running knock control up to -9 degrees across all cylinders and odd occasion -12. As soon as the car hits -12 it goes into limp mode. The customer was advised it a leaking diverter valve causing the issue.
Unfortunately it was all the following issues
Software was set to close diverter valve from 4000rpm - maximum RPM set point
Due to DV software issue, car was generating boost beyond 30psi (certainly no leaking DV here)
Redline peak RPM was increase way beyond save rpm point to now potentially cause valve float
knock protection was relaxed by 40% across the board
Air fuel ratio was also in all kinds of issues
the unfortunate issues above related in the following,
Intake manifold damaged due to excess boost
leaking exhaust manifold due to excess exhaust gas temperatures
Leaking high pressure fuel pump (due to incorrect installation)
What I have done for this customer is
re-instate knock protection back to stock
limited boost pressure to 21-22psi boost pressure
Replaced faulty high pressure fuel pump with new high pressure fuel pump
Knock control at most -0.5 degrees timing pull on one cylinder
same power
much safer air fuel ratio
most importantly efficiency and reliability
in light of this?
I do many things, on the mk4-mk7 platform, including hybrid turbos or big turbo applications, which I have a few under my belt already.
If JaseNZ or anyone would like to come on board?
there is so much more you'll gain other than a reliably faster car, but that's for existing customers to know and future customers to find out.
Others posted a few solid options as well.
So it's really your choice, always remembering the information provided before and after and knowledge are the most important factors to take into consideration
