Blackbear Performance Review

[Geotrash]

If you have a bidirectional scanner and use the mfr's codes by VIN (not generic OBD) is there a fuel composition or alcohol content value, or a reset function?

I do (hp tuners and a tech 2) and I’ll plug them in and find out. Not sure if a tech 2 will work with this rig.

So it’s been interesting. I’ve been doing a good bit of “general” maintenance (will post in the 3500 thread I have) but VIN lookup at the parts store has the question about flex fuel or non-flex fuel engine. I believe my truck to be non-flex as it was a fleet vehicle and came with a sticker “GASOLINE ONLY”.

I do not have a factory sticker indicating anything else.

That's pretty conclusive that it's not a FF system.
