For all the N/A'd LE5 owners
Alright, my summer course ended and I've had a week to fool around with all the various hypotheses I've had and worked out some pretty sweet timings for the exhaust and intake timings.
I've attached a log of my recent testing efforts as well as the most recent tune.
Mainly what i've been trying to do is maximize between MAF airflow and VE airflow. The results from the scanning logs is pretty good. It definitely pulls harder all the way out to 7k rpm.
Im still washing out the KR though but im trying to sort out real knock from phantom knock since my car can get kinda moody with that (it'll still show some kr even with tdc spark timing). Results may vary on that front
PE is leveled out for consistency with a small increase in richness at the topend as a tiny safeguard to reduce kr, though that'll get set to lean out later on once im happy with the cam timings
wrickm, i think you've gone the same direction I've gone. Your log looks pretty similar to what i've got going on though yours has got this weird jump/hump just before the top of the revs that bumps up the maf and ve. My maf values are a bit lower since Im still using stock parts but the ve airflow seems to be about the same
Pulling the timing on the intake back to 0* is where im at now for revs past 6800. What im still testing is how far I can go with exhaust advance to increase some overlap before it starts decreasing performance
