Shooting lean >4k rpm

[X64v]

X64v, setup were you using for spark control?

 

Using my pertronics ignitor in my '73 dizzy, with the vacuum and mechanical advance welded tight. Wired up through megasquirt as if it were points (backwards from a hall/optical). I do have an '82 n/a zx dizzy (mother had an '82, got hit in the front end 10 or 12 years ago so I've been pirating parts from it at will), so I can try wiring that in through the vr circut as well. I've been hesitant, though, because I was under the impression that vr dizzies were even more susceptible to noise/interference than a hall/optical/points set up.

I put about 5 gallons in the tank, and hit the gas, and sure enough, all the way up to 6k. Looks like I need to put some effort into plumbing in a surge tank. Up to now I'd just been putting in a gallon here and a gallon there. I suspect I mounted my fuel cell backwards too, I put the pickup facing towards the front of the car, but in retrospect, it would have made much more sense to put it facing the back, that way the acceleration would send the fuel into instead of away from the hoses.
