Thread: C950 22S issues

    The narrow band sensor that comes with the C950 can only run closed loop to a 14.7:1 air/fuel ratio. If you want it to run richer you have two choices:
    1) Operate it open loop with the narrowband sensor which is fine.
    2) Purchase the wideband kit and run closed loop to any air/fuel ratio you want.

    You can force it to run rich by raising the fuel map numbers so it can't take away everything. If I let the O2 run the idle it will not run. I do however, have the O2 working well under normal driving conditions. As in it's doing it's job. I have however had to raise the upper end to 180 under full throttle it goes instead of stumbling or starving. This however gives a large red portion of the map in the upper right corner. Seems to work OK though.
