Its the same .msq I ran before (trey 5-10-10). I can't see the log at work, but the hiccup is at the end of the log, where it dies.

Thanks for taking the time to deal with my problems and ignorance.

like i said before, i think your coils are taking shit. i bought my ls2 coils from this guy

If my coils are dying I'll just take the summer off, chill, then buy the DIY coils when someone makes a kit to wire them up with a mounting plate. I'm too dumb to figure out which resister goes where with all the other electronics that I don't understand and don't care to experiment with considering the cost of an engine or at the least $300 in coils when I screw it all up.

You could stand to run some more dwell. Try 3.0ms instead of 2.0ms of running dwell that you have now.

You could also try a DSM ignitor with your stock coil pack. Should be PNP and a pretty healthy upgrade over the Miata ignitor. The Miata 1.6 coils are ok; it's the stock ignitor that's weak-sauce.

Ummmmmm, so I'm a total idiot. It seems that the COP mounting plate was loose and vibrating in the front. I tried about 3-times to recreate the hiccup and can't seem to do it and I'll try more today.

I really feel like an idiot. Thanks for the help everyone.

Haha, glad you found out what it was.

I was experiencing blow out recently on the track. Turns out my OEM coil pack was loose. Those parts don't like vibration.

Ok, I went from head to toe through the wire harness and every wire looks "good enough." I went from the cops, to the igniter, to the fire-wall, to the computer. I drove the car today and its still blowing out and I've noticed the tach dropping out when shifting at redline almost every time. I will try the new to me CAS and 4-new to me Toyota coils. Any thoughts before I start my quest?

I'm really looking forward to DIY coming up with a how-to on wiring their coils.

Are you still on an MS1? The MS2 can significantly help debugging shit like that.

Mspnp 9093...so yes, MS1.

Ok, I have a new-to-me CAS, coils, and plugs and this thing is still dropping spark and backfiring at the "highest RPM". I've chased the wires from the CAS and the cops all the way back to the computer and they all look good with good connections. I have a track weekend starting in 24-hours, wtf else can I try?

If the tach on your dash is dropping down, but not on the MS its a problem with the coils

I'm definitely losing spark/power/bang-fire. The event also kills the log.

do you have stock coils/ignitor to test?

I lack an ingniter...unless I can use one from a 1.8.

What are the chances that something is screwed up in the computer?

Any chance I could modify dwell settings? I don't have access to a pesonal computer ATM.

what is it at now? optimal would be 2.5ms running on a MS-I.

I just have a feeling one or more of your cops is bad.

I replaced all 4 of them last night, again. I have a box of 16-Toyota coils, lol.

I wonder if te dielectric grease could have warmed up and dropped down to cause a short to the head like my window switch? I thunk it's going to be a long night.
