I was wondering if anyone could tell me which additional parameters I will be able to scan for once I update to the GM Enhanced OBD2 on my AutoXray? Does this increase the live data amd freeze frame parameters or does it just scan for additonal sensor inputs referenced for the CEL? According to AutoXray, this information needs to come from a GM tech manual and they don't have the info available to them??? Before I shell out for the upgrade, I was wondering if anyone could shed some light on this for me. The vehicle it will be primarily used with will be a '95/'96 (OBD2 switchover year) 4.3L Jimmy 4x4.
Thanks for any and all assistance, Andrew.
