Well I'm running a NA engine here so it must not be as noticeable. When I get some time I'll tinker with these settings again like you are suggesting and see if I can notice a change. Very interesting though.

well i have no real noticable problems running spark.
i guess the only thing would be low throttle, low rpm cruising, a little misfire. but not totally sure. it could be the acc settings fing with me or something.

otherwise it rocks hardcore! i think i have like 30* advance at 18psi.

That's just wrong...your gonna blow yourself up.

Are you sure you are using 93?

Yeah anything above 28 at WOT on my NA engine and it pings. I am using lowest grade pump gas as well though.

I also messed with the settings like you suggested and noticed no change fyi.

yeah it's 93, and no pinging here, i check the plugs after every time driving it and there's never been any sign of detno. i do also have low compression though

Well, News to report.

It seems that my ignition is breaking up at 7K again....everthing was working well until a few weeks ago. Under highboost, it wouldn't pull past 7K rpms....it just stopped. I pulled the plugs and found that I had gap errosion. all plugs had .045 - .050 gap on them. I put a new set of plugs it and it ran fine for a day. boostedsl2 came to visit and we took the car out for a joy ride and the igniton probelm came back...pulled the plugs and all looked well.

Started playing with the dwell and spark duration and it got worse.
I put it back to what I had it running at when it was running good and did a pull...but when it hit the probem area, I switched it to the limp mode by turnign off the 5v bypass signal and it pulled right on threw like a champ...so the ignition system has plenty of power.

So I'm down to a few possibilities:
1) Another bad ICM
2)possible problems with the MS code.
3)...I don't know of a 3rd yet
4) Need to try a NON-saturn ICM.

that's weird once again sam. have you been able to datalog it? maybe there's something that is pulling the timing?

I think it is that time to test a non-saturn ICM. There are several odd things involving starting and high RPM torque that seem like it could be my ICM too. Playing with the dwell and spark timings just doesn't seem to do much. I'd be willing to try this myself too but what hardware to use? I also have access to a digital oscilloscope so I could take a look at the waveforms from and to the module. But I'm not to sure what it should look like to begin with? If anyone would find that useful let me know and I can post.

last time i was driving my car, i didn't notice any problems at all, it was running well enough to hand that GTO's butt to him at the track
