My current tune is a modified version of what enjoyrth posted on this forum a while back. Running 450cc dsm injectors. stock z31 blow through MAF. I run a lc-1. Latency @ 690, K value @ 350. I adjusted min tpulse width where 10's were to 9's, also lowered the fuel load scale a bit.
Car starts fine, idles 700rpm when warm at around 15:1 afr, drives light load around 13.5 to 14.5 , cruises under light load usually from high 13's to mid 14's afr. My problem is under boost (15psi) its way too rich in low to mid 10:1 range. I believe because of this, my egt's are too high on boost (900-1000 degrees), that they'd come down a little if closer to 12.5:1 while under boost.
So any insight to what changes will help my tune get more lean under load/boost would be very much appreciated. Yeah i'm a newb at this, its a damn good challenge though!
Attatched is my current tune bin and also a log..
Thanks!
