Does anyone know how to install a air/fuel ratio gauge in a 2001 Tiburon. i need to know where to connect the sending unit wire(the purple one) in to the computer or O2 sensor. Thanks for all your help

The best thing would be to ring your local Hyundai dealer.

The pin-outs and wiring for the ECU changes nearly every year. I have an a/f meter which is wired to pin 17 of the ECU which is a blue/yellow wire. (UK spec tib)

Other guys on here with US tibs have used pin 11.

So goodness knows what your will be, anway ring the dealer as they have a catalogue of the pin out and wires colours for each model and year of car.

I hooked mine into the O2 sensor. I believe its the one on the left header and I have a total of 4 O2 sensors on my V6. I am going to be disconnecting it this weekend to get it prepped for my trade in so I will tell you EXACTLY where it is.

I had a guy that did a tonne of N2O setups hook it up, but don't quote me where its patched in.

Your best bet is to weld in a new bung and use a dedicated O2 sensor. Attaching an A/F gauge to an existing O2 sensor can cause a <i>slight</i> reduction in the voltage output in the O2 sensor, which could cause your ECU to see a slightly lower reading than what your O2 sensor is sending. Remember, the output of your O2 sensor is less than one volt, so reducing the reading by 2 or 3 hundredth's of a volt will make a significant difference.

If you check out autometer's (www.autometer.com) site, they recommend going to the factory harness, and not to the O2 sensort itself if you can't/don't want to connect to the ECU, since at some point you will have to replace the O2 sensor.

After rechecking, mine is indeed hooked up to the harness and not directly to the O2 sensor. My bad <img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>

ok. Reid, how do you hook it up to the harness. Where is the harness located and which wire to tap in? thanks
