i just bought a 350z for some track fun with my friends.. started looking into how they tune these cars ... with the uprev software for these cars you can data log everything we can plus get a/f ratio from the 02s... how is this done? what is the catch? i know with sct you can get bank 1 and bank 2 readings but we still need a wideband.. how do you guys think this works? does it seem like a good way to get a email tune? any help would be appreciated
