I know why I don't use Launch..I don't have time for all that BS...Autel or Leo resets the stuff in like 1 minute...J
I hear you Jason but Leonardo diagnostic system at $20 000+ vs Launch X-431 at $3300 (which I think is expensive) to reset service light and gather some basic information? What would you recommend in the DIY price bracket for us on this site?
