G'day guys, after buying a car with the tuner I tried the 10psi tune, pretty sure I did it right but now I cant start the car.... Everything works ie: select tune, hold program lights flash but p2,p3 together then F,p1 together back and forth then it goes F,p1,p2,p3 as the manual says ive tried all tunes on there with the same response....disconnected battery with no luck aswell any help would be great or its going to be towed tomorrow!!!!!
