I have been trying to dial in this new motor and cam for a few days now and need a little help.
LS7 440 CI
Cam TR251 551/559 114 LSA
I started off tuning SD mode Wideband only and now have the LTFT turned back on. Fuel seems to be doing really well but I am still having some weird issues.
I have been having cold start issues but I am pretty sure it was way rich. I modified the OL EQ table to all ones but have not been able to test yet.
I can not figure out this bucking issue between 800-1400 RPM's. Played with VE and timing and it is a little better but still bucks like crazy if you get the right spot.
At times out of the blue when I come to a stop it just dies and have not figured out why. I think it has something to do with IAT because it seems to do it more when the IAT is over 100.
I am attaching the current tune and log files so any help would be appreciated.
Thanks,
Kane

Anyone? Maybe it would be easier to just focus on one problrm at a time.
What is the best what to diagnose cold start. What are the basic tables to start with OL EQ ratio what else?
