I purchased 2 credits to do a single vehicle lisence on a vette. Updated my application key. It says I have 2 GM credits, but when I try to lisence the vehicle it only gives me options to do an entire year lisence or unlimited. No single vehicle. Please help if I dont get it figured out soon I'm going to have try and tune the car with LS1-edit. BOO!!!!!
Post a screen shot. What version of HPT are you running and what year is the car?
If the PCM does not have a valid serial #, single vehicle license is not allowed.
The car is a 2001.
The info log said the pcm serial #yyyyyyyyyyy
Im guessing this is what you are talking about.
Do I have to license the entire year to be able to tune it or get a new PCM?
you will have to license the year if you want to tune that PCM.
What would cause the PCM to not have a valid serial number?
Usually due to it being previously flashed & corrupted by the person or program used.
chances are that if you go to your local dealer and have them reflash the pcm with the newest software (based on your vin) you will be able to re read the file and license it
