#10562, "Tuning with Knock and Timing"
Jun-12-04 11:29 AM by Hult250R



          

Ok I think I might have the tuning figured out, but If I rev the car up in neutral to like say 6k I get knock
also If I go from a stop and make a 1-4th gear pull I get really high knock counts in 1st and 2nd (like 35) but none in 3rd and 4th... Is that normal? Help guys! Im lost....

Just went out and logged a run:
3500 15 knock 17* TIMA .83 o2v
4500 14 knock 12* TIMA .83 o2v
5000 13 knock 13* TIMA .83 o2v
5500 13 knock 14* TIMA .83 o2v
6000 13 knock 20* TIMA .83 o2v
6500 11 knock 11* TIMA .82 o2v

Im at 19 psi on 93 octane
small 16G turbo
no AFPR
My Lo throttle settings are pretty much -20% across
my Hi throttles are at -24 across the rpm range
any suggestions??

where should the TIMA be at? Ive heard it should stay at 19-22*

Also, when i make a pull the car kinda feels like im fluttereing the gas, its not a perfectly smooth acceleration.
