maftpro with no narrowband

i dont have a factory o2 bung in my new dp but i do have a wideband installed instead. so would this put my car in open loop at all times? and how do i go about tuning it without the narrowband? thanks

Enable PT Tracking on the MAFT and do the O2 sensor mod to turn out the CEL.

ptt is enabled automatically for me right because the stock o2 sensor being unplugged. that would also mean open loop too correct? not too sure on this though thanks!

No. Unplugging the O2 sensor will put your stock ECU in open loop mode all the time. It will not, however, affect the MAFT units settings.

Hey GRIM, do you know how to wire up a three wire O2 sensor to the stock plug? I am using a aftermarket downpipe that does not allow for the stock O2 sensor with the flange.

Here is the sensor I bought, http://www.amazon.com/gp/product/B000C8ZIKM

Sure. Wire the blue wire to your sensor input, and the two black wires to your heater + & -. The order of the heater wires doesn't matter.
