Bobby:
Your not the first gti-r but you are the first with that maf/inj combo
Sounds like what Nate said, my K and latency are out to lunch. Have you got a rom burner yet? There's a really good thread on how to set them up on a different forum, but I can't find it right now. Erm. In a nutshell:
-set your feedback to 00
-set your TTPmin to 0 and your TTPmax to 255
-set your entire fuel map to 1 (do not drive the car hard like this!)
-run the engine to ~3k and adjust the k value until the afr is around 14.7:1
-let the engine idle and adjust the latency until it idles around 14.7:1
-drive the car, staying off throttle and 4k rpm max, adjust k for 14.7:1
-replace tables and feedback with their original values (make sure to turn on feedback and include the feedback in the fuel maps)
-adjust tables so under boos performance is where you want it. For yours, this will mean adjusting the last two columns of the fuel map only.
-Post results to forum
With just a rom burner this is a long process (an emulator makes adjusting the k-value around quick), but you can do it in a weekend and you only have to do it once.
