Vin writing issue

Hello, trying to change the vin in a ECM from a 2012 chevy malibu to the VIN of a 2007 chevu cobalt that im going to try to install the used module in. I know i need to program the used module with sps2 and i have that, but when i bring it up in sps2 it sees the VIN from the 12 malibu, not the 07 cobalt. There used to be a VIN override in sps2 where you could change the vin, but not anymore. When i try to use hpt to chaneg the vin, it says OS/VIN not compatible, but i know for a fact these ecu's are compatible. Any help is great, thanks, sorry if its confusing

Customer vehicle = 2007 cobalt - needs ecu
Donor vehicle ecu = 2012 chevy malibu

Need to write the VIN of the cobalt int he malibu for program with sps2

Since its an '07 cobalt your best bet is to get TIS2000 its the old offline GM software that flashes cars from '96-08. You're correct the ecu is compatible but the software on it isn't.

in sps2 on the vehicle selection tab, don't click connect to vehicle as that will pull the vin from the ecm. instead manually put in the vin on the next line down and then make sure you select replace and reprogram

You can use HP Tuners VCM editor to change the VIN in GM ECM. First, under the Edit tab, press Change VIN Wizard. Next, enter your current VIN and press Commit. Click on the Write Vehicle icon. Under the drop-down menu, choose Write VIN/Tunerlock/VAT. Lastly, click Write. This may take a while, but after that, you?re all set.

Did that work for him? I do not see a reply

Is this option in an older version? The only options I see are Write Entire, Write Calibration or Don't Write.

It must be in an older version, I've been using hpt since version 4.10.7 and have never seen these options.

i have the same issue, mine doesn't have the vin/tunerlock/vat , what do i do?

You need to use another piece of software like DPS which is not something you can get. It's something that's Factory only and it's internal software so I know we're not supposed to mention it, but you're going to hear about it anyway. Or there are other ways of doing it... I could probably do it for you over like a remote TeamViewer session or something like that. If you want me to. Shoot me a private message and we can set something up. I work on GMS all the time and I can do all sorts of crazy stuff but I can 100% change that VIN to match. That would be really surprised if I couldn't. But yeah and I'll give you my contact info and you know we can work something out. I would just publicly say how to do it. I have no problem with that but it's kind of frowned upon because of the methods of doing it. So yeah.... Just hit me up. ��
