This one is puzzling me. I have MS ultra that I haven’t installed yet from my MS3 kit. Should be installing that shortly.

But the MS lite should be the more basic software. I’ve just always had the check engine menu available. Hmm. Gonna research a bit

Something else is just discovered.

MS 3 documentation appears to contain [Check Engine Light] info while the MS 2 does not.
