Is it possible to use SPS to change the software in the Truck modules from the original to a newer version, such as when I do my LBZ swap to bring all the modules up to the 2006 calibration to match the IPC (I have a 2006 IPC already), ECM & TCM? Near as I can tell, all the hardware, except the IPC, ECM, TCM & GPCM is the same from 03-07 classic (the PDM, for example, lists the same four bootloaders for every VIN I've looked at from 03-07). If the BCM is the only place the VIN is stored is and is what would prevent that, would replacing my BCM with one from a similar 2006 and using that VIN for my ECM, TCM and all modules allow me to bring the modules up to the 06 software?
Is there any way to get a VCI to add RPO UJ6 (Tire Pressure monitor) to the BCM or whatever to allow the system to be turned on? The stupid thing is all the data is there, but it just won't turn on.
