Wideband Sensor

[Vtec6000]

Can I replace the stock 02 sensor with a wideband like the AEM UEGO and use the AEM anolog output to give a signal to the ECU?

No you cannot as AEM wb puts out a 0-5v analog. The ecu expects a 0-1v voltage from a narrowband sensor.

PLX WBs output 0-5v and 0-1v analog, that WILL work.

Thanks will. Could I use a resistor to step the voltage down? If I go with a chiped ecu will it still need a signal from the narrow band even after been tuned using the wideband?

A resistor will not scale the voltage. With a chipped ecu/hondata or any other good EMS for that matter you can run the car in OPEN loop then you dont need ANY O2 sensors.

Cheers Will What do you think of the AEM UEGO as a permanent connected wideband?

Looks good, not as good as the PLX unless you Run a Gems, Omex or AEM ECU.

PLX = 0-1v & 0-5v
AEM= 0-5v & Serieal output

if using uego and want to keep oem sensor just get another hole put into manifold for uego sensor
