ignition timing???
what is the highest recommended advance typically run, I have a problem with the afc, everytime i lean it out the timing advance gets further and further. is there something wrong with my equiptment, i was logging +43 degrees with an otc flight recorder.
I dont know what to do, apparently it is very hard to compensate for 650s with an afc. I will be getting a utec soon but for the meantime I need some suggestions. thanks

i think since you're running richer conditions, the ECU is trying to compensate ignition timing for your richer/leaner a/f conditions. i think when you get your UTEC you should be fine in terms of optimal performance, as you will be able to adjust your timing map. are you running rich?

I think it's more cause you have really big injectors and/or a larger then stock piping holding your maf sensor. The result is the ecu seeing less air at any given point, thinking there is less load and advancing the timing....... If ya start out with higher numbers in your partial throttle fueling it would help a little, but I dunno what it would do to your fuel trim. Getting control of your timing(like with a reflash) would be key.
