timing ?
under what condition should the ECM provide the most advance? And about what should the total advance be at WOT? I read sompthing about 36deg. but did not know if this was total timing under load or what.
Thanks any help would be appriciated.

Part throttle cruise conditions have the most ignition advance to give the best fuel economy.
WOT timing varies based on the engine mods. Most figures I see are in the 36 degree range at WOT.
The part throttle cruise timing is somewhere around 10 degrees more that the WOT.
My TPIS Stage V Prom only has 28 degrees of timing in Power Enrichment Mode, WOT according to Diacom.
