18 ZL1 heads and cam build idle help
I just finished up my build and I'm trying to get the car to idle and run rich enough so I can drive it to my tuner. I have added a total of 50% more fueling through 10% increments until my wideband was showing close to lambda (swings from .9 to 1.12) through the VVE tables and bumped up the idle to 850rpm and it seems to idle much better. When I get on the throttle and let off it will hunt for idle and sometimes come back or even shutoff. I honestly dont have much knowledge with the Gen 5 torque based tuning so I wanted to see if someone could give me some suggestions to get this thing dialed in enough to drive 30min away to my tuner. I was already in contact with him but wont be back until wednesday so he cant help me out. I have attached a log and my tune below. The build is a M6 stock bottom end LT4 w/ ported and milled heads, 226/242 .635 .635 cam, ported blower, 2" headers w/offroad conn pipes and a monster lt1-s triple disc. Any help is appreciated
