K ive started with the calibration for the B18 revhard. I m running a plx and have it wired in per instructions minus the resistor. the car runs great with the closed loop checked off 14.5:1 on the narrow band. As soon as i check the box to go to wideband the car starts going all over the place and eventually stalls. I know im missing something but what is it?

It sounds like you are inputting the wideband signal into the O2 input. Check your installation against the instructions at http://www.hondata.com/techplxwiring.html
