How hard is it to change to 3bar fuel pressure? Is it as simple as changing the fuel map? If so, I'd like to do that temporarily. Let me know, thanks!

Have to change the k value. Search on here for a 3 bar .bin

Ok, so I had a random thought cross my mind a bit ago... My car has been running SUPER rich still... and I was thinking... is there any way to confirm this tune IS tuned for 370s? If it's not, then that could explain my gas guzzling problem perhaps... let me know, I would love to save my gas mileage and O2 sensor quickly, lol

Yep, it is tuned for 370 injectors at 4bar with the gtir maf. The easiest way to change it to 3bar is just swap the bin for the stock U13 bin- that runs 370 injectors at 3 bar and the gtir maf from the factory. If your still rich at that point stop fiddling with the ECU and fix the car.

Stock U13 attached (with speed limiter removed, RL set to 7700, timing map tweaked for 9.5:1).

Awesome, thanks a lot Calum. That was just a thought that crossed my mind and I thought I'd throw it out there. There is still the possibility that the O2 is wired incorrectly, but I'm quite sure it is not. So, next step is to check this tune... double check wiring... check all of my injector o-rings (AGAIN), and just try anything I can to get it not running so rich! lol

Thanks again guys

Actually this is a really good idea (running stock U13 bin with FP set to 3bar). Because it's a factory bin you know it works.

Yeah, I'm at work right now... but I'm getting ready to go on my lunch break to go flash it and hope it helps. I'll let you know later. Thanks :)

Finally got it straightened out. Thanks Calum. It ended up not being the tune, but it was the fact that the O2 sensor was wired up incorrectly. Appreciate all the help. Love the way the SR20 reacts to boost! :biggthump

Everything has been running good. I just bought an N60 now though, and need a bin to match everything from before, but with an N60.

bump. Need an N60 tune to match everything else.

i think this may work...i did NOT use these yet though but am doing the same set up....

Calum, any way you can confirm this is a correctly tuned bin since they are untested?

Thanks
