GTTuner Posted January 9, 2010 Share Posted January 9, 2010 I understand that. I have seen many ROMs that also have initial WGDC at 90% in low rpms. You must be refering to my map, LOL. Link to comment Share on other sites More sharing options...
black318i Posted January 23, 2010 Author Share Posted January 23, 2010 So I was logging for knock and noticed an insane amount of low RPM boost which was while in 5th gear. I didn't think this was possible. What could be wrong? Also how much of a MAF g/s gain should I be looking to get for say every .5 lbs of boost before it's considered inefficient?boost issue.csv Link to comment Share on other sites More sharing options...

I figure about 4 g/s for every 1/2 lb of boost. Full tune of 68HTA, KSTech 73 MAF, Racer X FMIC and ID1000s................by the DataLog Mafia!!!

You should keep your target boost lower at 2400 rpm and lower WGDC initial at 2400 rpm. High boost at 2400 rpm is completely possible in 5th gear. Log knock sum and WGDC next time.

black318i Posted January 25, 2010 Author Share Posted January 25, 2010 Target boost at 2400 is 14 psi. I left it there and lowered WGDC at 2000 and 2400 and all seems to be well now. Thanks again. Link to comment Share on other sites More sharing options...
