We're not trying to be funny, we're just two guys that have combined between us something like, what is it, 45, 48 years in GM dealerships?

The last bad ECM I saw in a GM looked like this...

HP Tuners only reads/writes 6 of the 8 segments, GM SPS writes all of them.
What are the full VINs of the calibrations you're trying to flash into it/them?
But hang on, how can it be a TMAP if there is only a single sensor output pin? These do not do any kind of weird multiplexing, they output analog voltage.
Odd that you wouldn't mention this...
Just get a proper LSA 3-pin non-T sensor.

If the replacement TCM is new-new and has never had any kind of flash before, HPT won't detect it. If it's a reman and still has some old file in it, or has a generic placeholder calibration, then...
This is what they look like with injectors or O2s bank-swapped

0hz if the MAF is removed, 1hz if it is just failed temporarily for tuning VE. P0101/P0102/P0103 set to MIL on First Error. Engine > Airflow > Dynamic: Dynamic Airflow: High RPM Disable = something...
If you only need to program one or a few ECMs it's easier/cheaper to just buy them used and pre-programmed to a VIN you supply.
First, find a file in the repository with the stuff you need. Take...
My oil pressure gauge has a needle that will sweep the full range and everything like a real gauge but in use it only has two positions, zero or 40psi.
At least I think I understand the reasoning behind exceeding the max on that one, it changes the shape leading up to/after the peak and the dwell time at 194F, even if the value the ECM uses never...
Every cell that got populated in the trims error chart is lean in that log, MAF Fail is = 100hz, P0101-103 are set to No MIL instead of First Error...
So the file needs to be set up by someone...
Prove you are human: How many forward gears does a 4L60E transmission have?
This happens in other tables as well, depending on year/platform.

In da picture...
So if 0->1 is "44" (whatever that means, for now), then at 43/199.4F it will be still off, at 45/203.0F it will be on, and the actual switchpoint will be somewhere...
Seems like it would also be pretty easy to test yourself, by logging all the related stuff.
You can't write the truck's stock file back to it if the only file you have is one that was made after the old trans was gone. You'd need to have read it out while the old trans was still in it.

These look... similar. But different enough to maybe make a difference. The EGR valves look identical but are different part numbers, I don't know what is different between...
If O2s or injectors are swapped bank-to-bank it creates a feedback loop. As long as everything is good, everything is good. But if either side starts to go away from zero then it just keeps going...

The file you've already read out of it is everything that will ever come out, that is 'your file'.
