One major development:
We first noticed the engine would start up fine after messing with the priming pulse width, but once started, it would lope and barely run at all - almost like a car dieseling from after burn once the key is switched off.
Then we noticed the "pulses" of engine life when
trying to idle matched up with the light from the timing gun. So, the pops of the cylinders actually firing were in sync with the gun lighting up...we realized the coils must not be firing regularly. This is weird because there are no sync errors coming from MegaTune.
Long story short, we now realize the V6 Toyota dizzy looks very similar to the 4age 20V one
except the spiral on the 1 tooth out put is reversed. So, the v6 dizzy looks to be rising edge, and the 4age one falling edge. With the v6 dizzy hooked up to the car and powered by a drill, the spark timing is actually consistent. But, when the drill is reversed, the spark out put looks like when the 20V dizzy is hooked up. If we could some how reverse the polarity on one of the sensors, I think this car would actually run right now. Since the ground is shared, this isn't an option.
With a scope hooked up, it appears that we might be having the trigger one and trigger 2 overlapping, b/c the V6 signal does this when we spin it backwards (much like how the 20V dizzy works normally).
Let me know if any of this is unclear.
