Looking for help reading and or programming gm ebcm on a 2009 Colorado I thought it was can? But seems to only respond to class 2 commands I got the seed, and os info. Anyone save the utility and sps event from one of these? I want to change the rear wheel reluctor from 40 to 55.

it is class2. This is why it has an E67 and not an E38.
