Fitting AEM wide band sensors with stock ECU

[sparky]

I've just fitted AEM dual channel wide band oxygen sensors including the controller / interface. I have an AEM ECU to fit later, but for now I'm still running stock ECU using the narrow band outputs from the AEM interface unit.

Every thing is working fine, except the ECU thinks the sensor heaters are not connected, and reporting this as an error code. Of course the heaters in my new UEGO sensors are working just fine, except now they're being driven from the AEM interface unit. Hence there is no connecton to stock ECU heater lines.

I'm looking for suggestions on the best way to "fool" stock ECU that heaters are fine, so the error code is not reported. I put my multi-meter across the stock sensors heaters and they are about 13 ohm resistance, so I'm tempted to simply fit a resistor in circuit where the heaters originally connected.

OR , you could simply plug the OEM sensors back in and hang them under the car somewhere.

Keep in mind that if you use resistors you need to (A) use resistors with enough wattage and (B) place them where the heat produced will not harm anything.

that's one good option...
