Victorgaragesmg Posted November 9, 2018 Report Share Posted November 9, 2018 Help me get a good run map for this engine I need the trigger arm voltage and basically good start map with boost and 3bar GM map sensor. 600cc injector. I am piggybacking the stock ecu to keep run the auto tranny and DBW Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 11, 2018 Report Share Posted November 11, 2018 I dont see much wrong. Below is your BREBET4 log with the wasted spark log overlaid on top (pink traces). In the wasted spark run you are commanding about 6deg more advance and about 10% less fuel so thats going to make it run noticeably different. I dont see any obvious signs of trigger error but you would need to get an oscilloscope on it to confirm arming threshold. Sometimes with piggyback installs the trigger filtering in the OEM ecu can mess with the trigger voltage at high RPM so it would be worth getting a scope on it if you dont find anything else.

Victorgaragesmg Posted November 11, 2018 Author Report Share Posted November 11, 2018 Its only on the 3500-4000 under boost that is missfire.. 4500-6500 fine if I keep pushing the pedal.. It is slightly different from the tune table because i cant tune perfectly when i get missfire right ? This is still confusing for me.. please help me..
