It costs a couple bucks (EFIlive + RoadRunner PCM), but wow did they come up with a nice idea ... for those who have used EFILive (or other tuning programs), for now it already does the AutoVE-tune (to correct fuel amount to get the desired AFR) by itself in realtime ... just drive the car, and it will correct the internal table(s) so that the fuel amount is just where it needs to be ... regularly, it takes a couple of hours to get the VE table tuned in decently (drive a while, re-flash the PCM, drive again, re-flash, etc.) ...

And no, you still need to have a general idea of what you are doing
