The PCV makes changes in 1° increments, with "0" being the value given by the ECM. Thus, a "-10" retards the timing 10° at that point compared to the advance imposed by the ECM. So, if the ECM is dictating 20° of advance, placing "-10" at 500 RPM @ 0 TP would effect 10° of advance at that point. I'm only able to change down to 500 RPM, so maybe it's not worth doing.
Does sound like 500 would be beyond the point where any start timing drop will have benifit.

The puppy lasted until fall. Now in teardown mode for new build
Do you know how much the tuner retarded the timing and at what RPM? I thought about going -10° at 500rpm @ 0% TP in the PCV ignition table just to release some burden off the starter.
Does anyone have an opinion about the wisdom of this move if I'm not having any issues with the SE255 cams in an otherwise stock TC96. I also have the SE comp installed and have no more starter knock.
Iclick, sorry but this was the first time the tuner had tried that, he had heard of it but not done it....next time I talk to him I see if he can find it...
this was on the older SERT.. bought it in april 07
