After that we will be testing on actual engine/vehicle.

Thanks for posting Graham! !

I've spoken to both MS and Torqhead. I have given Matt at MS the contact info for Torqhead. He said they were going to reach out to them. I'll see MS again at PRI this winter and press again. MS has the engine end down pretty well and Torqhead has the CCM data stream figured out. Really wish they would get together and sell their info to the one that wants to take an LT-5 ECM into the market!

Jerry,

Thanks, I knew I was asking early.. I am sure you will do your best to meet the needs of owners

I have one of the megasquirt LT5 ECUs. I would love to be able to update it for full functionality.

I like that TorqHead uses an OEM PCM, that gives us OBD2 functions/data

Ignition module testing has now verified input and output signals to stock ecu with stock harness, picture attached.

Next to verify full range of ignition advance and retard per the limits in the 1995 calibration, using this because it is the maximum stock values.

Graham, is that big header connector readily available from somewhere? I am in need of one for a project

With all this discussion of the DIS module, if it were me, I still had Barney and its DIS still worked, I'd get the plenum off, remove the DIS module, clean any dirt/debris of it, spray the connector with contact cleaner, clean the mounting surfaces on the module and the plenum, then apply fresh dielectric grease per the service manual.

The grease is important because its how the module sheds heat to the plenum.

Hopefully the replacement DIS module project undertaken by Jerry and Graham is successful.

Hib,

Are u suggesting dielectric grease for mounting of ICM?
Its white heat sink grease. Just wanted to make sure that was clear.
