yeah, thanks for trying man.

more video

I went a month overlooking it:? I just hope it still runs great in the morning

wow man thats awesome. Was that a raw egg in the little bowl? Can you say "Rocky"

well I feel stupid. I just set the plugs to .024 and beat the hell out of the car for about 30 min at 16lbs with out one stumble. I could of swore I tried .025 with no luck. But I've rewired so much stuff, cap, rotor, test lights everywhere..... I had them set at .028 when I took them out of the car. Now.. its run great in the past, and then went all to hell the next day. So time will tell. so far problem fixed.

11.5 with methanol

that was my big question. I started thinking it was fuel because it went lean. But I don't think its fuel or coil.

MSD 6a my gap is .028 I have run .025 in the past I can try putting it back down to .025. Again I have run the same setup with no trouble for months. At one point I turned the accel enrichment off. I'm going to try putting the gap at .025. plugs are NGK bpr7es-11

I think its been a month now that I've had this problem. It all started after a night of tuning at 20 lbs of boost and getting the revs above 6k rpm. All went perfect, until the next morning while dropping it into 4th to take an exit. I felt a stumble. Also that morning my turbo (holset) started smoking. Rebuilt the turbo that week no more smoke but the stumble is still there. Let me define the stumble. It feels like I'm hitting a rev limit. and seems to only happen above 14lbs of boost. But sometimes it does not happen at all. If I lower the boost to say 12lbs, the car will rev to 65k rpm. During the stumble the tack stays in place does not jump around, fuel psi builds and holds steady does not drop off, wide bands goes LEAN during stumble, but the injector pulse width and duty cycle hold steady. Sometimes it will pull through, so rpm holds at say 48k rpm, fuel builds to say 50lbs and holds. But then boom the car takes off as though nothing was wrong. I've changed the cap and rotor with Nissan parts. check the plug wire ohm's, new plugs. put a test light on fuel pump before and after the relay. test light on coil, neither losses power. Nothing has changed from that tuning night a month ago. I've ohm'd the injector wires, signal wire from dizzy, TPS wire, put noise filters on all 12+ going to megasquirt. And I've rewired the CLT and IAT sensors with shielded wire. I'm left thinking its my turbo? I rebuilt it but did not have it balanced. I've done that before on my other holset but I've checked EVERYTHING and thats what I'm left with?

this is me back in the MX days

Oh yes.... the good old motorcycle training days. As an old stunt rider myself I had to go through this as well, ha ha ha, I can still Larry's face when I cracked that whip for the first time........

I only use "1 2 3"

what I thought was funny is most of the topics are the same that you see now.

That's a good idea.

ok I think ms1 does not show that big number like ms2 does. But I no my timing matches. Just reading some posts and started wondering.

I've been going over my settings and my trigger angle is 0, and the trigger angle addition is +45. Is this right? 83 turbo dizzy MSD 6A I've been reading older posts and it seems like my trigger angle should be about 60??

woo hoo! you did it!

thats "1 quick Z":icon14:

nice!

good to no guys thanks. I think I'll leave it where it is.

my methanol bottle is inside my car. The cap is vented to let air in as the methanol comes out. Is this safe? Should I move the bottle under the hood with a low level light mounted inside the car?
