So I guess here are updates, not that anyone has a clue any more but maybe someone will chime in with something I've missed.
I had two sets of toyota COPS. I put all the original cops back in the car and another GOOD CAS and it worked. briefly. I drove it around town, boosted it (1.4bar), did burnouts and beat on it. Took it to the track, drove 5 laps and it started to reset and break up again.
The original cops are loose and can lose connection by popping out which is why I swapped them out. Soon as I put a new (second set) coil in it would make the problem worse.
It would work for half a lap with the original ones in and then start resetting and stumbling again.
I was having alternator charging issues, the over driven 140A alternator creates a lot of drag and slips if the belt isn't super tight. I've been tightening it to help my problem.
I've also never installed the 10k MFD Capacitor in my system. However I'm not entirely convinced this is my problem, because a week worth of beating on the car (after it was built and tuned) and I didn't have a single problem while tuning or at the track without this Cap. The wiring is all brand new mil-spec.
All my sensor wiring runs through a bulkhead quick disconnect, idk if that is creating any kind of problem, but it is an automotive grade connector and shouldn't cause that kind of problem.
Ideas? I did decide to ditch the Megasquirt (Found out it was an MS1) and I bought an EMS4. I want to make sure that I can fix this problem so that my new ecu turns out to be a worth while purchase, and not an expensive toy in the middle of a headache problem.
Thanks for your help if you read this whole thing
