Transistor swap for conventional ignition

lazytv · Post by **lazytv** » Mon Jun 20, 2016 6:26 pm

The transistor ignition with resistor and ignition control module is a pain in the ass and the older the car gets the more prone to failing.

Anybody bypassed that for the conventional ignition system?

Honestly the only thing that would be an permanent fix/update would either be a Motronic 1.3 conversion or a PNP Megasquirt. Both require replacing the entire engine harness. 1.3 is basic, MS requires learning about the system and tuning, which is more of a commitment unless you know someone or willing to pay someone for the install and tuning. There is no way to adapt what you have,(that I know of) since the igniter module is integral to the system you have.

Or you could always go backwards and use the ECU, harness and dizzy from a car like your 3.0, paired with a Crane or Pertronix conversion to get rid of points/condenser.

Thanks for the input. Right now I'm ready to push the e12 off a pier. Starts up every other week. Frustrating as f*ck.

I have always wanted to learn more about MS and its tuning process. Do you have any good information sources besides the MS FAQ? Or an example applied to an older BMW?

Search youtube. There are symposiums and workshops for megasquirt. If you take the time to really learn it and understand it, you'll be in great demand in the vintage car community, because very few commit to learning it, they just pay someone else to do it. (hint)

I have some experience with re-flashing and removing immobilizers on VW ECU's. I didn't have a real reason to try to mess with any BMW ECU stuff until i got the E12. Thanks for the advice though, will definitely look into deeper into MS.

In fact, i already have the water damaged E34 ecu needed haha, just need to get save up to get the rest of the kit.
