Does the spark angle looks like it would be the cause?

 

aggressive overrun settings.

 

Any other thoughts?
AbeFM Doesn't seem to think that would be the culprit.

 

no actually, when i saw the drop i was thinking fuel not spark angle. looks like the cas lost it's signal...

 

Thats closer to what we we're thinking,
This started since I reinstalled the MS after having removed my turbo and ECU for the OEM setup to get my car ref'd, after getting pulled over.
Except for this time I went full standalone, but ever since, the car has been doing that weird bucking thing, and I haven't really been able to get my LC-1 to be working either. would you think there'd be any problems with having the cas installed while not in use? it ran great before going back to oem.

 

Need more info on your setup. Seriously. I could ask 32 questions so we could try to start diagnosing this, or you could just post the info on your setup. Looks like you got mad noise too. Turn off your acceleration enrichments, turn off overrun, turn off any rev-limiter, turn off EGO correction, post your msq, post any datalogs, all the details on your setup, year, motor, mods, MS version, when it worked, what you've changed, what mods are done to it, pics of your MS board, etc etc.
