But until the OEM ECMs depeleted from even being fixed, I will choose that OEM route.

That said, who do I contact at DIY auto tune asking about the GM fuel data?

This was the last email I had, my previous email to him was asking why there was never a final release of this ECU:


Unresolved issues with the dash serial bus communication. We were able to run the engine itself very well. Now that we've successfully cracked communication on a Ford dash, it's likely we will take another stab at it.

FYI, these people already do comms w the CCM using a 411 PCM. Unfortunately, just for LT1/LT4.
This solution would be somewhat involved for LT-5, but it would be ideal from the standpoint of providing a plentiful supply of PCMs while eliminating the need for the ICM.

Yup. And they are never going to make a product for the LT5 and they would have no reason to provide their proprietary knowledge to DIYautotune. Sucks.

I wasn’t suggesting that TH could share their proprietary info w MS. Apparently, they’re swamped w interest on the LT1/4 conversion. Discussed w Paul at TH an LT5 conversion. Doable. In fact easier than the LT1/4 because we don’t need a crank sensor component. He could use our existing crank signal, and apparently could convert it to 24x for the PCM. And also use the cam signal to sync up.
Its involved in terms of needing to re-pin the harness for the LT1/4 connectors, and then convert the LT5 cal to the 411.
The 411 can accomodate MAP, but we would need additional fuel and spark tables plus ability to control secondaries, all of which doesn’t exist for other LT or LS motors.
Th solution that =Jeff= has implemented would be outstanding if it could ever be replicated.

Couple things to clarify. DIYAutotune isn't Megasquirt. They are an authorized manufacturer/distributor. I find it hard to believe that doing 16 injectors with our DIS is easier than simply adding a crank sensor to an LT1...

What solution has =Jeff= implemented?
