closed loop operation

[ike84]

I found this on a bike forum page. Looks like the dme is looking for a range and not a fixed point, which may make this a lot simpler!

If this is the case, I be should be able to feed .45V back to the dme and effectively disable the feedback of closed loop operations! Then I can control the air fuel mixture in both open and closed loop operations with a signal amplifier on the MAF sensor.

Here's my real question though - why has no one else already done this?

Yes they are saying the same thing I described.
Bottom line is the DME/ECU is attempting to create an average of 14.7-1 AFR
or Stoichiometric.
