Making use of used modules?

[kelly]

I have a ton of junkyard modules and do some SPS programming on the side. I'm rather green at all of this but would like to get around the limit for swapping modules into other cars. As a tune shop sometimes we will get cars with just butchered or locked tunes and it would be nice to get a new module in with a fresh SPS flash.

Could someone just point me to a good thread to read about getting around this? I don't mind putting in the work. I'm just a bit over my head in it right now.

Another thing I would love to be able to do is just get a stock file from the SPS library directly. But maybe that is for a different post. It would just be super handy to go back to stock first. With a lot of the later cars it's hard to find a matching stock file in a online repository.

Most of what you need can be done through techline

Sorry I'm not sure what you mean. I cannot obtain a stock file via flashing through techline because I cannot get past the global A/security code requirement to program the PCM.

I think the code to program an older module to global A calibration is 6455 or 6544. I can't remember off hand.
I've programmed a 2010 Corvette E38 ECM to a 2010 Camaro which is global-A via techline.

Is that what your trying to do?

So the code to be able to flash ALL Global A's to something else is the same or did you have to find that for each ECM?
