OEM Wideband Sensors

I was wondering if it would be okay to use the stock wideband in my 2002 Toyota celica, to communicate to the AEM-FI/C-6 Piggyback system. Or would I have to purchase a performance oriented wideband, Like an AEM wideband sensor? Thanks again.

I'm not familiar with the AEM piggyback but wideband sensors are measured through current consumption by the sensor controller, which is built into the oem ecu in your case. So if the piggyback doesnt already get that information from the ecu and requires say a 0-5V signal as an input then an aftermarket sensor is likely required. Probably worth a call to AEM to find out what your optionns are.

Hey look they do have an option. check out the manual. I think your part # is 30-1911
