Re: A/F ratio and ignition timing
So on the 14b anything over 18psi is no good basically. So I need to raise the boost a tiny bit and get the AF in the low 11s or so and then slowly increase timing until it knocks. And thats all the power the motor will push on this turbo.
Here is my spark map right now. I added a little timing around 6k and have yet to test for knock. I rarely see that part of the map anyways. It seems that you run real low timing around 4k or so. I always thought you should start around 20 or so at 3k, drop to 15 around 5k and increase a little more toward redline. Check out my map and let me know what you guys think. I hit about 16psi @ 3500rpms.
