I have been battling this lean tip in issue from the start of tuning.. I have a Ls3 to LSa conversion running 6 lbs of boost. Stock cam and such. The car only has a lean tip in in open loop while cold and open.loop hot start. I have tried adjusting just about every setting via transients timing tables it will spike to around 1.03-108 lambda which will produce spark knock. This is only in first gear take off. The car is a manual.
Once the car is in c.l. operating temperature the lean tip in issue goes away. However in c.l. mode at 95 degrees, motor still cold, it has the lean tip still until operating temp has been reached.. any suggestions would be appreciated.
