Someone without ME7 understanding going for R32T DQ500 combo.
That's going to end well.
At this rate maybe in a few years it'll be tuned right, maybe never.
Your best bet is pay someone to tune it who has done this before. It is very difficult to get this running correctly.
Also requires ASM mods.

The guy who build it brings me a lot of cars, and asked if i want to try to get this done.
We'll see where it ends..
Maybe it's to difficult for me, but i try to learn as fast as possible.
With the info on this forum and some damos and logic thinking i hope to get quite far..
It is running quite ok now, but a lot still needs to be done.
Doing 600 hp @ 1 bar now.
So wish me luck guys..
I hope you guys still want to help me with my noob questions..

You can count the people on your one hand who could get a such project working properly on this forum.
They've also been at it for many years.
Ultimately it is possible to make power on WOT by skewing the torque model, but the car will be an undrivable kangaroo on part throttle.

I know this will be a big challenge..
But i will learn an awfull lot of it and if i won't succeed he'll need to find someone else to map it.
We'll see where it will end..
It also has cnc ported head and almost 300 deg. cams and can turn 8800 rpm.
That's why it makes quite some power at low boost.. and i checked it was 1.1 bar for 600 hp.
Biggest problem is no one want to tune the car because of it is running ME7.
But stand alone ecu's can't work with the DQ500..

idle is way better as i thought it could be.
880 rpm nice running, i thought i would at least need 1000 rpm..

In which country are you located? =)
You would ideally need some asm-mods for mono-lambda control + load cap etc, and on top of that a good MAF.. Before even attempting to tune this.
Theoretic flow across the throttlebody is something that really needs adressing.. And ofc timing and all other normal tuning aspects.
If youre struggeling to dial in a set of injectors, you are definitely in over your head here..
That said, its not like it cant be done, im sure given pointers, help and TIME, you can end up with a decent result and good driveability.
(Ended up tuning three r32 turbos with power in the 450-750whp range, when i had a go at the 032CN ecu..)

I'm from the Netherlands.
We'll see how far we will come, i knew it wouldn't be easy.
And if doesn't work, he'll need to find someone else to tune it and at least i learned an awful lot..
Mono-lambda seem to work ok now, no load cap yet at 600 hp.
Trottlebody control i modded quite a bit, will take beter look when i try to make driveable.
First try to get idle, WOT and starting perfect.
I will try some more next week and i'll let you guys know how it goes and what troubles i'll run into..

it will be a challenge I can think of a few ways, start an IDA project and define relevant functions you will learn how it works. If I listened to how many people say "it cannot be done, I would do nothing" good luck mate, 7 months of ida ahead I fear unless you have an a2l. p.s MAF function is easy to find follow the ADC or xref a word. |

Looks like DSG box is broken now..
Made 666 hp on 1.17 bar boost.
I did a run with rev limiter bit higher (8500) and after that gearbox won't go in gear, gives code from gearselector and inputspeed.
Checked everything but looks like hardware issue..
Too bad..

Hi TurboJohan, I have a similar project started a few years ago, and back then I talked to a guy called VR6specialist: http://www.vr6specialist.nl/Perhaps you can get some advice there..? |
