any trouble codes when it stalls?

It takes about 10 seconds of decel but its not exact. The only thing I see that might be it is flag 1 bit 1. Mod Select BPW or A/F. Hell, that could be for something else, I don't think I have ever touched it. The stall is normally right after 800 RPM as well. Your battery voltage isn't too good either.

i thought that's the alpha-n switch... i flipped it once on mine but it didn't make a difference...

I was eyeing up that bit as well. Last night I burned a chip with the lb/hr and gph values filled in. This was a blind shot in the dark but it seems better. However I only had the ride into work to test this out. I'll do some more testing this evening.

I'd still like to have the assembly code if that's available.

So it hasn't stalled out in two days and 4 trips. However, I do get an anomoly where odd things occur every couple thousand samples (2 examples below). I've been running without the center console so I have some concern that the ECM gets warm and flakes out. I'm going to replace the console this evening and see how things go.

It doesn't appear to be a heat problem. Drove around a fair bit with the console on and no problems. I'll probably look over the assembly code this winter and see if I can't figure out why those values might cause this. Thanks guys.
