Tuning with 02 voltage on 2G. What voltage anyways?

you have to advance the timing in the higher rpm due to the fact that the piston speed is higher, whereas the flame propagation is approx. the same.

essentially, you have to light the fire sooner because the piston will hit tdc sooner.

I'm not really sure what I did to get it to work out that way, I just made my settings early on and went and tried it out. It's not that hard to get it right with the little turbo on my car. If I can repeat those results with the 50trim I'll be lucky..

My wife helped me tune the car, maybe she will lend her tuning services out for a fee of $50 (that I will keep of course.. )
