Twenty Thousand Degrees Advanced

**ericburgundy** · 07-19-2014

I think Robertlsaar is on to something.
It makes sense that the ecu would try to retard the timing, but then mis-interperet the negative data.
It also makes sense that super-retarded timing wound backfire the intake.
Would a ADX make difference here?
Could you guys suggest/link one for my $OE bin?

lets see the adx you're using it can probably just be fixed

also i really dont see why the calibration shouldn't be set up to clamp timing to 0 degrees minimum anyway. since when has a car engine actually wanted spark after top dead center?

lowish RPM, WOT with a quick throttle transition to get there(triggering burst knock protection or torque management in the process)?

i could see it going ATDC from that.

how do i upload my ADX to this thread?

If you click "go advanced" you'll be able to attach it as a file. Or send it to me and I can attach it.

well, i was right: 16 bit, but no sign.

try this out. it will likely fix the advance being reported incorrectly, but it won't help with how the engine is running.
