I am new in the ECU tuning. Does the wideband O2 sensor can only fit tuned ECU like Hondata? Is it working in the stock ECU?

 

A wideband generally will not work with an ECU from factory. Most factory ECUs are programmed to read the voltages from a specific narrowband O2 sensor. If you use an aftermarket EMS, you're most likely going to have to input the correct voltages to reflect AFR. If you buy a wideband that can simulate a narrowband, then it'll be fine to plug it right in.

 

Thanks bros.

Any brand of sensors have you mentioned simulate narrowband function?

 

PLX. It will still throw a heater code though. For a stock ecu the best thing to do is add a bung and run two sensors... your stock one and the wideband of your choice.
