I converted mine to the yugo system http://www.yugoparts.com/ign3.htm
I am now rebuilding Bosch Ignition Control Modules. I use the original Bosch aluminum box, remove the old printed circuit board and replaced it with a new solid state GM HEI ICM. This will fix ICM's that have burned out or ones that experience thermal failure and won't start when the engine is hot. The rebuilt units use half the amperage and produce a stronger spark than the original. Just ship me your failed unit that has an intact box and electrical connector. I'll usually have a couple units already built, so turnaround time should be fairly quick.
The $75 price includes the rebuilt unit, the box cleaned and painted with silver epoxy paint, seams silicone sealed against moisture, and return shipping. Let me know if you want the option of my returning your original box, instead of a core. If you want a specific name brand HEI module, let me know and the price can be adjusted.
Message me or send me an email with orders or questions, jnolta*integrity.com.
Cool !
$75 in your paypal account.
I bought this X 21 years ago, it has had many suspensions, paint jobs, & interiors since.
Reviewing my decades of notes, the one thing it has reliably done is fail to hot start.
Think if it is a thermal failure of the ignition module !
Thanks for offering the service of bringing these into a more contemporary design.
I will stay in touch ( & ship back the core in a timely fashion ! )
Can't wait to see if this solves the mystery..

OK, back again.
Had a full week of rain.
Put your module in last night.
Beautiful workmanship inside !
Runs great at revs, but cuts out below 1100 rpm.
Huh.
Dies whenever I pull off freeway, & most times at a stop sign.
Also cuts out when leaving a stop if the revs drop below 1100.
Challenging.
Swapped to original ( that I had in a labeled box to send you ! ) & problem goes away.
Back to the new one & the stalling returns.
I wonder why ?
Good ground.
Could the wires to the reluctor be reversed ? Would that make a difference ?
I'll try to put it on an oscilloscope in the next day or so.
I'd like to get it working before I mail you back my core.
Any suggestions ?
How's your hot start issue ?
Have you done the brown wire mod yet ?
Cheers !
