What ECM we talking about here?  I just bought a device that allows you to clone GM ECUs I have been busy with many other things so I only goofed with it for a few minutes but I did successfully read an ECU and then write to it.  It clones and that's not to say that it allows you to change the VIN of the ECU but you can dump the eeprom and flash to file and then program the eeprom and flash with those files.  So if you can modify the eeprom contents and the ECU doesn't reject the modifications then you could change the ECU VIN if it is one of the compatible ECUs.  The device I am speaking about is called io-prog.  Hope this helps.

It is an E92 so according to the list they show it would be compatible, just doesn't say specifically it would change the vin. Let me know if you get a chance to play with it some more and if it is possible to do that.

I USE OTHER PROGRAM FOR ECM VIN CHANGE....

I think HP might work but they specifically spell out that the VIN change would not be compatible if the operating system is not for that VIN and in my case it is not. 2019 OS is different than 2020. Unless I am reading it wrong, I would be concerned about spending the money and not knowing for sure.

Hello,

Doing some research and found this site, I am totally new at this and have a quick question. I am currently working on a 2020 Camaro but have an engine and transmission from a 2019 SS, there is a difference in the Transmission and TCM.  Question is it possible to flash the TCM as a 2019 then change the VIN to the current 2020 or does it even matter? Will the BCM and PCM even look at that VIN? 

Reason for the change is the 2020 uses a 10L80 MI12 and the 2019 uses a 10L80 MF6 transmission, SPS will not allow me to program the MF6 for 2020 so was thinking of programing it as a 2019 and changing the VIN. 

Also will this software make that change possible? I would be using VXDIAG interface.

Hi Dano,

I have 2020 Camaro SS and running into similar issue "Shift to park" issue. Do you think i can buy a used off Ebay and reprogram to my Vin? Or does it need it to be entirely new from HP Tuner?

IOPROG not support 10speed TCM, program sps the original car vin, save calibration file, convert to dps format and write to donor TCM, vin not change on this procedure, to change vin,, send utility file to troy and he will do the vin change file for dps
