I don't know if you are referring to me as the OP but I'm not abandoning the atmega platform, I just look for ways to cut down on "moving parts" I'm moving back to the dev board. I can't wait to get home on Sunday to play with this. My wideband setup that was on the race car had a 5v o2 output for tricking stock ECU's into thinking there was a narrowband sensor in line. Once I get the MAP and TPS sensors sorted, I think i'm gonna look at adding that to the board. The whole thing could possibly end up being an add on unit to the MPGuino, because as it looks this is going to take up some space that the MPGuino doesn't have.
