PW and DutyCycle Spike causing stall

Post by m0ntecarloss »

We have the engine running pretty good on Megasquirt now but at the end of our tuning run the engine stalled on us repeatedly at idle after running for a few seconds.

I managed to catch one on the log and everything looks normal except right before it stalls the PW jumps to 32.....

Any idea what might cause this?

This is MS2 with v3 board. Runnin on a small block chevy...

Can I have a look at the MSQ file. This pulse seems very random! Unrelated to AE for certain. You have me curious!

Here it is. Sorry it took me a while to get it : )

I really probably should have put this post in a different section, I'm not so sure its a tuning issue....
