That would be much appreciated, it's always nice to get as many OS's mapped out before we release a controller. Nothing worse than people booking cars in for a tune only to find on the day it's an OS we haven't seen before.
A 2012 Equinox is probably using the E39 ECM and T76 TCM (v8 should auto detect that anyway).
I haven't been able to figure what determines when a front wheel drive vehicle uses the T43 or T76, but if it's a 6 speed auto it'll be one of those.
Cheers,
Ross
