Well every other site I've been to says Q16 on the upper right with the 3 wires off of it control ignition. So now I'm confused.

Ok I will go look at his thread....

I just dug into my harness. Any particular reason my brown and white/green ignition wires are reversed at the stock ECU boomslang connection? According to Brains DIY post on how to build your own MS, the brown and white/green wires are in opposite spots than what my car has.

Anyone?

Are you actually tracing these back to the pins on the DB37 or just going by the colors of the wires? I might have reversed the colors of the wires but the pins should still correspond to the correct pin numbers on the DB37.

Essentially too much dwell fried the two NPN transistors in Joe's inverted spark out mod, and I just have to replace them and change the dwell back to 2.5ms? If so this will have to be logged in my epic fail book.

Nope. The car just fired up. I reflashed the MS and put my msq back on. And before firing it up I tested every coil with each spark plug at all 4 COP connections with my brother cranking the car. And they all sparked. It STINKS like fuel though... and it's running a bit rough. Time to go do an oil change and take the car for a drive.

I also set the dwell back to 2.5ms before starting it up.

Who knows what went wrong but it runs now so I'm not complainging. Must have been jostled a bit when I moved the unit and damaged something in the stofware.

Holy wow, I never changed the dwell from my base map. 5.5 cranking, 4.4 running

Like I said, i've had weird things happen when unplugging, moving and replugging in the megasquirt that were only fixed by re-burning the firmware and MSQ. I haven't had this happen in a very long time, but it happened a few times when I was first installing and troubleshooting my MS.

Glad to hear it wasn't hardware related.
