New Member but not new to LSx. However all my time has been strictly gen3 stuff...
Father Swapped a 2011 Colorado from 4 cylinder to LS1 and it runs and drives okish. But starting and idle is rough and fueling is lean. He recently passed away and I am attempting to fix these issues.
It's a LS1 with 58x reluctor wheel and cam sensor. Using E67 ecu.
Has headers, mild cam on 114 lsa, and Fitech 102mm intake and GM 12613411 injectors
I am looking for a starting point for starting and idle. I haven't been able to find any good reference for this.
Any info on where to start or reference file would be much appreciated.
Attaching current running tune. This is what I am starting with.
*EDIT* The truck does have a persistent P0341 - Camshaft Position Sensor A Circuit Range/Performance (Bank 1 or single sensor) error. It's has a gen 4 timing cover with sensor. Not sure if it has the original crank sensor. Did the gen 4 require a newer type crank sensor??? Attaching a log.
Thanks Guys.

Found major contributing factor, Used a bore scope to check timing gear. It's a 1x gear instead of 4x. Hopefully after swapping this, starting will be better and can work on getting fuel more in line.
