Can the 96-97 Coil & Module work on a 94-95 LT1?

EDIT: Apparently the problem is going from 94-95 to 96-97, but not vice-versa. Whatever changed in the 96-97 ICM apparently doesn't piss off the 94-95 PCM. But a 94-95 ICM will piss off a 96-97 PCM.

No; unless you are also using a 96-97 PCM. I know the '96 Y-body ICM and 94-95 Y-body ICM are different. Info: https://www.corvetteforum.com/forums...schematic.html

Admittedly, most of these only use the '96 coil, but not the '96 ignition driver module.

Sure it can be used, just change connectors and you are good to go.

I would like to convert a 96 LT1 to the 94-95 PCM. Seems like it's possible with the original 96 ICM and some wiring work.

Just swap knock sensor modules, plug PCM to car and you are good to go. Did it couple of times.

No need at all to touch the coil or ignition module. Swapping a '96 LT1 to the 94-5 8051 PCM is nearly
a plug and play affair. I've done more than I can count over the years, mostly in the days long before
TunerCat '96 LT1 support.

If you're planning to use the Tach output from the PCM, you will need to address the number of pulses.

The knock sensors changed from 95 to 96, as did the number used depending upon the donor vehicle
(F, B, D or Ybody).

Is this an engine swap, or a stock '96 application where you just want to use a '95 PCM? Knowing the
exact platform will help narrow down the answer.

Hi Scott,
The engine is from a 1996 F-Body Camaro auto trans that will be converted to manual trans. The application is an off-road only Jeep . . . Oregon Sand Dunes playground. https://traveloregon.com/things-to-d...creation-area/

Very easy to swap 96 coil/icm into 94/95 harness, just need parts/connectors and a few minutes of wiring work. Don't forget the coil wire is different for 96.
