what is the best unit to use on obd2 automatic transmission 6th gen accord 4 cyl in order to tune it right? has anyone done it...? And I dont mean those "custom" burned chips from JET or any other little "power control modules" from other manufacturers that claim mad hp increases with just a "turn of a ***". I'm talking something I can tune and retune on the dyno and would give me...hopefully some control of shifting in my auto, and maybe allow me to switch between 2 maps(for street and race).I was looking into aem programmable stand alone, but they dont make one for an automatic. Anyone out there using greddy e-manage? I was thinking that might work. But really I need ANYTHING that would WORK on my automatic CORRECTLY...Is that too much to ask for...? or are we still living in stone age?

 

what about an apexi unit? vafc or safc?
