#1188, "RE: loud backfire/studdering under high loads w/MS spark" In response to In response to 2
Don't use the "Minimal..." setting, it will yield charge times which are too long at lower RPM's which heats really heats up the module and too short at high RPM's which will result in a misfire. My current dwell settings are 25/5.5/0.1, the cranking dwell is very high because I measured the stock cranking dwell and that was around 36ms! A shitload of dwell indeed, so I tried to match it in megatune but it won't let me go above 25ms. Although if your current cranking dwell numbers work just fine, stick with those.
Dwell control works a lot better with the new code releases. Anything after 025i6 is game.
I've been messing with my spark table a bit recently, I have replaced the original file with this new one so all of my old posts with my spark table should automatically update themselves, but I'll post it here too.
