About to throw in the towel nailing down idle
***I don't want to read all this...just take me to the procedure!***
I am getting VERY frustrated trying to eliminate hanging idle, surgind idle, idle that stays at 1200 until I come to a stop then will eventually meander down to ~900, idle that dips when I push the clutch in then surges up to 1500, idle that won't come down below 900.:banghead:
I have been trying to develop some sort of methodology for E40 idle tuning and I have been anything but successful. Everything I do seems to result in a worse idle. I'm getting ready to remove the rev limiter, put her in neutral and put a brick on the gas pedal.
I guess I am just looking for any advice/guidance for tuning idle parameters on LS2's. I've tried numerous things around the minimum RAF and idle adaptive spark and like I said, everything I try makes things worse. Gen 3 idle tuning was SO much easier and more consistent!
Since I can't upload a damn tune while at work reference my tune here: http://www.hptuners.com/forum/showpo...8&postcount=40
Summation of needed changes
Alright; so what did we end up with as to the cure to big cam idling problems?
Please speak in laymans terms if possible and provide insight as to the theory along the way... ;)
Thanks!
