Hello Mark here, what I would Like to do is this: make a Clone of my existing E92 ECM using a spare ECM. I have tried to Replace and Reprogram a used ECM with SPS with a MDI and the VIN from the Used ECM will not change.
Can I use hp tuner to clear the VIN of the doner ECM and then use SPS to Replace and Reprogram my stock calibrations? I think I can make a clone if I buy a New ECM, not sure if I can do this with a used ECM .
2015 GMC Yukon XL L83
E92 ECM serv# 12656993
No you cannot.
OK got that , can I purchase a new ECM then use SPS to Replace and Reprogram my stock calibrations with my vin. this would then be my clone. I'm not an expert with SPS and it allows me to go pretty far before it creates errors. So any used ECM is a brick unless I have some means to clear flash rom area and reload the gm bootloader
Unfortunately I've never used sps so I'm no expert either.
You could do that, however you will probably need to reprogram it in your car. GM recently imposed some restrictions when it comes to bench flashing ECMs.Quote:
