I finally finished my build on my g37 and I'm trying to base map it with uprev and I can get it to start and idle just fine but as soon and I touch the gas pedal it turns so rich it pegs the sensor out at 10:1. But I can get it to maintain a steady 12.5:1 as long as the rpms are steady. Iv adjusted everything and I can't get it tuned in. Dose anyone have a tune they can send me just something a little closer than the POS base rom uprev sends you. A base tune off of a boosted performance kit I'm sure would be super close. My setup Is exactly like the boosted performance kit except my MAF housing is the stock 2.5in housing and my turbo is mounted in the rear. Same size turbo, fuel injectors,and fuel pump.
Any help would be appreciated my ecu part number is jk79b but a jk79c will also work for some reason because that's what uprev sent me for my N/A tune.
