how can i hook up a heated 02 sensor to a non-obd ecu. the closest i can put my O2 sensor is on the downpipe close to the turbo. my sensor is not giving correct reading because it's not hot enought. only when i drive my car hard and the O2 gets hot enought to give right reading. can i just hook a heated O2 sensor to an ignition relay or does the ecu control amount of heat of the O2 sensor in OBD1.

 

sorry to say but no you cant, im trying to do the same thing.
- are you using a obd0 ecu ?
