secondary injector module/ecu

Then how are the ECM's interchangeable as per Marc?

Because the OEM ECMs have enough inputs and outputs..

So the PROM then Defines the ECM's inputs and outputs.

if you mapped it out the Power key, knock and EGR use pins that are unused on the 1990..

Functionality was there in the ECMs, just not used

So one would think that would be even easier on the megasquirt ecu. Which begs the question, what is different on their ecu between cutoff. I sent them an email.

I believe these are for sale any time, you just may have to wait until they get a couple orders before they build. I know when mine was built they had 2 or 3 orders. I ordered mine in March of 2016. Took about 2 months to get, with some communication issues along the way.

I hope to get it up and running this summer.

Torqhead out of Canada has the CCM data stream figured out for L-98, but they don't have the engine control for LT-5 secondary injector control done (low demand). I've been trying to get MS to talk to Torqhead so that "they" can solve the CCM issues. Have not had any success so far.

In what aspect? To the best of my knowledge, the only things they hadn't worked out were the trip computer/mpg stuff.

That would be awesome.
