I don't have the other vehicle or ecm/tcm to check for a couple weeks.
REALLY awesome work
I have another ecm to check if you like.
ECM E92 Security Seed: D8B1D54006
This is a 2018 but still had the t43 and only had the 2 byte seed for the tcm.

Here is my 5byte tool "In-Tech" here is the last key for the seed you posted...

Does it matter that your tool called it an E98 instead of an E92? I'll be back at the dealership on Monday and will try it on my buds truck.
Thanks

D8B1D54006 Can you try again? Notice the third digit is a B and not an 8
Thank You

Thanks,
That matches what I "sniffed" while I was working on my buds truck who is a service tech at the dealership. I was really interested to try a different key to see if it was valid too.
Good job, I can't even fathom the amount of work it took to accomplish this feat

Yeah it would be a handy tool to have, what is it worth?

I don’t have a big use for it now but as cars get older I’ll definitely
be looking for this in a few years. If you need further help with other ecu’s I can definitely sniff some programming sessions for
More seed key examples. Hadn’t been bothering. Now I have a reason, lol.
