I have a lq4/4L80e with ls3 heads and ZL1 supercharger GT 11 cam 215/231 .631/.644 118 CL.
Was having lean start issues changed Bias to 1 and left filter stock settings.
Having cold start and hot start issues engine dies, will run fine on cold start once engine warms up.
Tried starting today and logged the start up, cannot keep it running ambient air is 48 degrees.
Have been working on VE table still work in progress.
Any suggestions on tune would be appreciated.
Going to attempt to post tune and log files,
Think I might have found the problem. Lsa supercharger boost bypass valve is controlled by the pcm on the ZL1 thru a actuator.
Seeing that gen 3 pcm can't do that( not wired into pcm and even if it was the pcm does not have the ability to control actuator) had to change routing of vacuum lines to bypass the boost bypass valve actuator in order for it work properly. Which is something I knew, just always got side track and forgot about it.
Still would like suggestions on my tune, any help is always appreciated.
Thanks
