look in between the FINS there will be a Exx Number then i can help you find something that reads it. IO Terminal Works good on these and Bitbox depending what ecm it is exactly

That's a P12 US market tools can read and write such as efi live or hptuners . GM used that ecu for only 2 years or so. What do you need changed on the calibration?
