6.7L ECM & TCM Reading

[Duramax 6.6L]

So 2010 rams are not included in the reading?

No not yet, I believe I saw that the 2010 and 2011 had some sort of encryption.

I am waiting for the 2011 and I have a 2012 on order.

The encryption apparently applies to some 2009's as well.
At this stage don't bother trying to read the 2010+, it's a different ECM to the original 6.7L one.

So will the 2010-12 be next?

[GMPX]

A bit of a wild guess, but the 2010-2012 will not be looked at until 2012. I am away for all of November so nothing will happen with R&D during that time, up to that point (and probably beyond) we'll be working on the pre 2010 6.7L.

When did this changeover occur or how does one tell if they have a readable or non readable ECM ?

Build date of 3/09 or later I believe I'm sure some one will chime in.

Is that the truck build date or the engine build date ?

Thanks

Truck build date or any ECM that was flashed by the dealer after that data with the boot loader security.

If it was flashed by the dealer, normally there's a sticker on the upper radiator support showing the ECM flash.

[someguy]

Once its flashed by the dealer, can someone reflash it to a previous version (with EFI Live) ?

Thanks !

Any updates on the release of the early 6.7 stuff?
