Good afternoon guys and gals, I have a b20v setup with a chipped obd1 ecu. I'm wondering how would I go about wiring up a air/fuel ratio guage? Do I need a wideband? Or can I just tap into my o2 sensor? Any help is appreciated!!!!

 

If you want a AFR gauge it will come with everything needed, very simple install, put the Wide band sensor where the stock O2 sensor goes and wire up the power and neg. Use a fuse tap to get power from the fuse box or use a plug like the cruise control or dimmer to tap power from. Use the thermostat to ground the gauge.

If you need to wire it up to the ECU to display on your laptop when you data log you must tap into D10 ELD in the ECU harness and use that to display the AFR. There is still more to setting it up the ECU and I'm only familiar with Hondata, I'm not sure what program you are using in the chipped ECU.

okay sounds simple enough with the wideband lol and its just a phearable chipped obd1 ECU.

 

Do you have any mods to the motor or is it basically stock? If it's stock, LEAVE IT ALONE. That A/F ratio gauge isn't going to do anything but powered on and show some lights and numbers.
