Hello guys I am thinking about buying hptuners but have a question before I buy. I have a 1988 jeep with a 01 5.3 that has a ecm I bought from a guy that I don't know what it came out of. Question is What vin do I use? How do I set this up?
I will be buying the pro version, I figure I might as well get the upgraded version while I'm buying. Thanks for any input Robert
