Victorgaragesmg Posted November 9, 2018 Report 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

Adamw Posted November 9, 2018 Report Posted November 9, 2018 You haven’t described what the problem is? Quote
Victorgaragesmg Posted November 10, 2018 Author Report Posted November 10, 2018 Ok here is the problem.. every time i hit 3500-4000 rpm the car start missfire Above that and below that range is fine.. Quote
Adamw Posted November 11, 2018 Report 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. Quote
Victorgaragesmg Posted November 11, 2018 Author Report 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.. Quote
