I have an All test Brainmaster 2 Model 3250 scanner and was curious about one thing it only goes up to 85 and my car is an 86 will it still be accurate? I was running it on 82-85 Oldsmobile, then I switched it to Full function 82-85 and I got different readings for each. It seems to be a really good scanner and is capable of a lot, so I am hoping I can use it. If not anyone want to buy it lol?
