FrankenFerrari - V12 Ferrari 308

[ssmith]

The urgency to replace the ECU is gone because I got it running again, a bit of a hack but running is running

The ecu I have has 10 spark outputs, #1 is fried.  With many newer ECU it would be a non-issue as i could just pick a different output but ecu automatically assigns 1-6.  Tonight though I had all 12 cylinders running again.  The software lets me select 12 cylinder coil on plug as if there are 12 outputs because early HW did have 12...mine actually does have 12 too but the softer can't access 11&12 correctly.   But that wouldn't help anyway, output 1 is dead....but it also supports 2-stroke and allowed me to select 12 cylinder 2-stroke so now I can waste spark off any 6 driver I want. The spark is fixed

Does your ECU support both passive and active coils? If you were using the passive coil driver and you fried one output, maybe you can switch to the active coil driver and use external ignitors (VW 4D0905351 per 4-cyl). The drivers are so different that I would expect one might be fried and the other might work, I think the active driver would look like a 5V square wave if you wanted to bench test it (don't set it to active with the coils still plugged in!!!)

Does your ECU support both passive and active coils?

No, it a 0-5 25mA output that is now a 3.5-5V output.

The 2-stroke setup works and starts the engine but the ecu loses its mind after about 10 minutes and timing goes funny

I found a place that says they can probably repair it and I might try but that is plan B. Plan A is this thing https://shitboxparts.com/ running probably modified (bigger tables for sure) rus code, I agreed to be a beta tester for them and help with user manual.
