Hey everyone, got a weird situation. I tried to read my mom's Cadillac to see if I can turn off the Auto-Stop feature at red lights. However, hp tuners didn't automatically figure out her ECM, and I have to choose it from a list:

How would I go about determining which ecm to choose?
Only xt5 on the supported vehicle list is 2017-2018 3.6L.
12726508/12689093 by application, an E01 (whatever that is). Pretty sure that's one that is encrypted and has to be sent in to be unlocked before you can do anything with it.
edit: Same ECM as the weird 2.7L full size trucks, not sure that one has even been cracked yet. Don't think it has.

Has been cracked, but no mention of anything but the 2.7L. You could always contact them directly or open a ticket.
Good idea, I'll create a ticket with those same screen clips and maybe they'll let me know once it's available for the 2.0
Thanks again for the insight and advice
To determine the correct ECM for your mom's Cadillac, you can check the vehicle's service manual or look for a label on the ECM itself, which is usually located in the engine bay. Additionally, you could try reaching out to the dealership or a professional mechanic with the car's VIN number for more specific information.
The real question is it worth $499.99 + credits to turn off the autostop feature?
