After looking at other calculated PIDs, I came up with this: -- MINE.WHP return pid"pcm.trqeng"*pid"pcm.rpm"/5252; Not sure if I need...

Alright, I think I just made one. Probably doesn't work, never done this before. Open kimono, I never left the old 7.5 scanner software even though...

Ive made some progress, but still running into idle issues. Latest tune attached and updated comments in this thread. See the oscillation at idle? Im...

Does the key information need to be extracted from the original ECM? Or the TIPM? Can it be done with EFILive or switch to Witech?

All in ecm programming. To make what the other modules see for “keys” match.

When you say a few extra things for security, other than the VIN, is it done on the ECM or is it additional programming on another module? Can you...

It would all come down to the additional modules in the truck. Hopefully in 06 there weren't many. I'd imagine you could maybe replace the modules...

As Al said, I've never seen a 2005 or newer file using the '7603 OS. Probably because(from memory) 2005 and up LS1B's had a different pedal and TAC...

Using the 19 cal but yes same thing. And yes theres stuff outside of efilive needed to use to full potential on cp3 truck

So let me get this straight real quick. You're using OS 52.20.03.00 that is associated with cp4 based calibration ID's on a cp3 truck? Any editing...

Correct

Are you running one of the two OS that efi live currently supports csp5 on the 5th gens?

Bit more to it then that unfortunately. Need few extra things to make security happy etc. If its 68rfe truck will need converter pi curve programmed...

I don't know if that will work. It is not something that EFILive has worked on, tested or explored. Regards Paul

Your Torque converter isn't affected. If you have a light duty, it locks/unlocks in 3rd. You are on the right track. Just prevent hunting by...

So the option is to use a 19-21 for a 22 Cummins flashed with the calibration and VIN of the 22. Will this work and is there anything else that needs...

Thank s Joe, let me know when you get a chance to look I'm thinking it may not register misfires in SD because it's looking at airflow ...

I haven't looked in your ctz, but the MAF DTC may be preventing the misfire detection.

The files I found with that OS are all 2004 vehicles. Do you need a specific engine/transmission combination? Al

Anyone know where I could find a file?

Dont bother with 56mph. do 63 for 5th and 75+ fpr 6th. I have a 369 and 5th locked at 56 lugs.

Thanks for the reply. I had to get a controller from a third party, programmed to my VIN.

Nope GM gas only

I've tried it many times with no luck. The OS is pre programmed into the controller. GM MDI and TDS web is the only way to do it on your own. I...
