I just purchased a used U7194 (v.9r03) that was supposed to be unlocked.
My vehicle is a 2008 Silverado 2500HD 4x4.
Under "show last tune written" there's a 91 octane tune, a calid, and a vin # from what appears to be a late model 'Vette.
I have plugged it into my truck and it does see my VIN but I haven't tried to download anything yet.
Does the presence of the other VIN mean the unit is locked to the previous vehicle?
Thanks.
Just got a U7194, have question

RE: Just got a U7194, have question
Most likely, yeah it's locked. Did you buy it used? or new? If its new, I would imagine the dealer you bought it from should exchange it for you. If it was used, could you get the guy to restore the factory tune back to his car? That would unlock it from his vehicle. If you can't get it unlocked, you has a very nice code reader.

yup, you got ripped man... that tool is still locked to the other car... you can't use it to tune or anything, only read trouble codes.
that guy needs to restore the original backup to his car in order to unlock the tool, otherwise you're sunk... cuz diablo can't/won't unlock it.

Well, I used Paypal and paid via credit card so it shouldn't be a problem.
I contacted the seller and I'm waiting for a response.

UPDATE: Seller stated that it was his tuners mistake, gave full refund, and said keep it.
At least there's still some honest people out there.
