im looking to get a range of what you guy's leading and trailing ignition timing is at. could you post some numbers for IGL ant IGT and major mods, so i an compare it to mine?

 

Have you noticed that the actual timing at idle does not match the maps.

You have to use the DATALOGIT and change your three idle speeds to 0 inorder to enter timing that the PFC will really use.

17 with 3 split is mine.

 

I have noticed that actually and wondered why that was the case. Datalogit will be one of my next purchases

 

Because the PFC has a self learning idle, at closed throttle it changes timing and fuel to achieve a smooth idle. If you zero out the idle values, then at idle the PFC will do whatever timing you tell it to do.

 

I was wondering the same thing. What do people run for an idle split? Best split for emissions? Best to stick with the stock 15 degree split in this case?
