WBO2 back in action!
Connecting the wideband to the Megajolt won't really get you anywhere, besides maybe being able to incorporate some sort of failsafe (i.e. IF full throttle AND mixture > 14:1 THEN spark cut). I'm not sure whether the Megajolt supports any math/programming in that fashion though... If you wanted to datalog, it would be nice to have some key inputs like RPM, MAP, and AFR for general logging and tuning purposes. That would be the main reason to hook up the 0-5V wideband output to the Megajolt, IMO.
