Is there anywhere I can look to get a few pointers on cold start tuning, specifically after a cam swap in an LC9 5.3 with an E38 ECU? Cam is a Comp Stage 1 Thumpr cam 218/229 duration, .541/.530 lift, 111 lobe separation. VE table seems to be dialed in, and after playing with idle settings to calm down surge in drive, I have lost my ability to cold start without peddling. According to the logs I have from before the idle adjustments my throttle blade would be around 28% open when cranking and now it goes straight to 5-6% as soon as cranking starts. If I hold the peddle down till the throttle blade registers in the mid to upper 20's then it will fire up. I attached a copy of my latest tune file. This tune seems to start fine once the vehicle is to operating temp and has been tested down to around 115 degrees Fahrenheit coolant temp at which point it also started up without peddling. The temps I am having issues starting at are around and below freezing. Any help will be greatly appreciated!
