could anyone look at that tune, this is a low compression LS7 (9.2:1) with big cam and YSI blower and 80 lbs injectors running MAF only with enhanced 2bar SD OS.
almost no noticeable bucking between 1000 and 2000rpm, stable idle but can get easily unstable with AC on. RAF matches pretty much what the idle config gives me, just added 1.5 g/s to it between 600 and 1200 rpm. Nice drivability at part throttle but it is easy to upset idle with AC on where it occassionally underswings/overswings and sometimes dies.
AC press has been increased by 25% but did not show much effect.
was playing with most idle parameters around but it sort of always happens to get upsetting idle quality with AC on. I may have overlooked something.
BTW, WOT not dialled in yet
log starts at frame 1600.........stable, then after a quick blib it starts ti beciome unstable, also wenn coming to an abrupt halt. Almost never when clutching in very late at traffic light.
