AFPR is NOT a must with 650s. Tune way rich then back out from there. Put everything at +10 and work your way down. Keep track of your knock count and timing. Not your o2 readings. RRE has base lines to use I believe. They did when I started tuning anyway.

What about tuning Lo throttle and Hi Throttle?
How do I tune each of them?

With the knock and timing, Is the knock high when its lean or rich?
Also what about the timing??
What about looking at fuel trims, some sites have said to monito that too, What on the logger am I looking at for the fuel trim? I have the MMCD program
