Well i finished wiring up my plx wideband to my ecu so i could use the sensor for my o2 since i broke mine on a rock and after i got it done when i head out to work i get 15 min into the drive and cel comes on pull over check it out...code 21 Vtec spool..what the heck so i go on to work and on the way home it does the same 15 mins then cel ...except this time i get code 1 and 21 primary o2 and Vtec spool...so this continues a day or two and finally today it came on as soon as i started the car. i am using the narrowband wire (grey) from the plx unit going to pin 6 (Primary o2) obd2a on my obd conversion harness..anyone have any ideas?

Disable the O2 heater within Hondata. Make sure you have Vtec Revs set within Hondata as well.

that is the reference i used when installing and o2 heater is disabled and im not sure what you mean by vtec revs are set but im pretty sure that should be set..i have vtec revs set at 5000rpm if thats what you are asking and the box is checked. also that diagram shows the white wire being connected to the o2 input am i mistaken or is that the wideband signal wire.
