The only way to flash it in is the Pcm recovery function using the file you want to go in it. Modules 7 and 8 are not written by TC so I don't know if they match what your using or not. Do you have a J2534 cable? I have an OEM log in you have helped me plenty times in the past.

I don't have a J2534 cable for GM. I was thinking about buying a Mongoose, do you think it will work good with OEM flashing system, or do I need another one?
Thanks

I use a mongoose GM cable 90% of the time and has worked great. I have a MDI units but it's large and bulky compared to the mongoose. The MDI2 was just released I ordered it 2 weeks ago it ran $700 but have to be a GM dealer I was able to run it through the Fleet account. Like I said using the PcM recovery function will flash it.

I will try the PCM Recovery later today. Thanks a lot

You can get a chinese clone of GM unit for 200$. They are good quality and you will only need a subscription.

I had these files

**LRT** · 03-19-2016

I have a lot of 2007 and 2008 files. If you post the cal that you read out of the E38, I will look for one with the same 7 and 8 segments.

Well I updated my roadrunner software and the code patch was available. Funny since I was only 1 or 2 versions behind.
Truck is running now

Thanks folks, appreciate all the help

Let's see if somebody has a calibration compatible with this ECM. This is the ECM the truck came with and was flashed somewhere else. It was running on 4 cylinder only (3,5, 2 and 8 running, the other 4 have no pulse). I checked wiring from injector to ECM and it's OK.
So I tried another ECM, disabled vats and it ran fine.
I want to flash the original ECM with a stock CAL before dumping it, I suspect the flash is bad but I don't have a compatible one to test.

Best Regards.

Great info!! Thanks a lot
So, my ecm has a 2008 OS. it came from a 2007 truck, completely stock so it was updated by the dealer.
It is 12622161, 6.0L truck
I just got word from TC, they say that the OS PATCH option is greyed because there is no patch available for that OS

Hope I can find a compatible .cal for this ECM or else I'll need to use HPT
