    Hello , I have a standalone ecu purchased off of eBay from a seller named andrey-AWD. I've installed said ecu and linked to tubing software. However my throttle body didn't respond at all. Which stopped me from getting it tuned on this ecu. This was a PNP solution for the AEB motor ( stock ecu...

    What tuning software package options I should look at for a Stage 1 (California 91 RON gas) tune for my 2019 Alltrack? I wish to start simple with something that is CARB compliant and easy to monitor using basic data logging tools. There seem to be multiple options; JB4, APR, Unitronic...

    Greetings, Currently, I am swapping a 1.8T into a mk3 golf cabrio and have my wiring sorted and about ready to fire. The ECU has already been sent off and returned with the immob defeated (no tune). I tried cranking the car and unfortunately my starter was bad, but I was still able to read the...

    I've been hearing great things about modified ECU chips. Better response, small power bump and even fuel economy. Does anyone on here have one they are looking to sell or could point me in the right direction? I have seen Techtonics selling them in the states but after postage and local taxes...

    Hey all, I just swapped a 3.6 vr6 to my '06 GTI and I'm running into a couple issues at the moment. 1. When attempting to code the ECU to 0000072 (FWD, manual trans), I get "Error 31: Request out of range - Coding Rejected." 2. The ABS module does not want to communicate with the ECU The ECU...

  11. Vans and Transporters - all years
    A few months ago coming down a hill the HT coil failed, and the engine cut out, and from about that date my problems started. The vehicle details are at the end, but here's the story: It can run very well for miles/weeks at a time, then starts to mis-behave for a while (maybe a few miles). When...
  12. Tiguan (PQ35)
    Hello everyone, I’ve recently been looking into chip tuning and I was going to buy a Unitronic tune, but I’ve found software like VAGSuite and EDCSuite that claim to do the same thing for cheaper. I have little knowledge of how tuning works besides it remaps the engine. Does anyone know what my...
  13. Jetta/GLI VI
    Hey all, I either suck at searching or this question hasn’t been asked (seems unlikely) but all my youtube, google, and vortex research has been inconclusive. I need a new ECU for my wife’s Mk6 Jetta (2016 1.4T) and found plenty of used cheap options on eBay. If I swap in a used ECU will I...
  14. Golf/GTI VI
    My car has an APR stage 2 tune on it. My cooling fans stay on 100% at all times & about 6 minutes after the car is shut off. I’ve replaced my fan module already (didn’t fix it), and have spoken to APR and they said it’s an ECU issue due to it not being sealed properly. They say they cannot...
  15. Golf II & Jetta II
    I was looking at picking up a 1992 Jetta MK2, 5-speed manual. Has anyone installed an aftermarket ECU? My end goal was to put a small(ish) turbo on the engine, and from my research, I have found that the Digifant 2 system cannot handle boost. I'm aware that this is not the easiest thing to do...

    I want to know if any of you have bought the ECU upgrade for the 1.4t from unitronic and what are your thoughts about it? Also, do you know if the APR ECU upgrade is compatible with the mk7? I got confused while searching for the answer. Maybe other options that I didn’t mention that would be good?

    So about 2 months ago I bought this car (2006 GTI 85k miles) for my son and he wanted to get his cigarette lighter working and he put a 25amp fuse in F24 (data bus) in engine bay fuse box (not saying this was the issue). Then realized it was the wrong fuse box! Sometime after this the car would...

    Hi guys. So I have fully "rebuilt" my AC system. 2007 Jetta 5 TDI DSG. New pipes, new lines, new solenoid for the AC compressor, compressor inside was spotless, not a speck of dirt. Problem came when I wanted to regas it. The guy pressurised the system to about 2.8 bar as I can see it on...
