What is the diffrence between the two tuners.
yes the 1 can be tuned by a sct tuner then flashed to your ECU [thumb]. The 2 allows for user adjustability within the preloaded file plus code reading for diagnostics plus data logging features! I'm looking into one of these also, or possibly the pro racer package. but thats another story .elliottcarlose said:but can the car be tuned the same with the 1 by tuners I mean can you buy tunes from the dealer and load them on the 1 to tune cars also
