Misfire at 3000 RPM after upgrading to G4

Recommended Posts

Hi,

 

I just upgraded my ECU from g3 - g4, and everything works fine, except that I get crazy misfire at 3000 RPM. Below, or above that, everything works fine. 

It's a 13b single turbo engine. I have attached the old map, the new map, as well as some logs. 

If anyone can help me identify the problem I would be very thankful!

 

Best regards,

Sebastian

It looks like trigger error to me, there are spikes in RPM and dwell gets pretty erratic around that area.

So does it have a custom 36-1 wheel fitted on the crank?

A couple of settings I suggest changing as yours arent normal:

Change trig 1 filtering to level 1.

Change trig 1 arming threshold to match this example:

Thanks! I'll try that. Yes it's a custom 36-1 wheel. Not sure why the settings are as they are but they're the same as they were in the G3 map that worked OK.
