ok cool, the last car was a 90 dodge daytona. When the 02 went bad it stalled completly. If these cars dont do it thats good. I wasnt sure if removing it and running it with it out would cause issues till i add the tune.

Thanks for the help

If you get a CEL with the Wideband its because your ECU is still reading the 02 sensor you have your Wideband in.

After I put my Wideband in , I got a CEL contacted my tuner (1turbofocus) Tom on here from Focus Power and he sent me a fix to disable the CEL and no more Cel for me . :)
So you didnt drill a new hole in the pipe you just replaced the correct one?

See thats what i was wondering, if i put in the wideband with the car stock and remove one of the stock o2 sensors to put in the wideband sensor if it would cause the ECU to keep the car from starting. If it just throws a CEL for a few days i can live with that.

My last car had an o2 sensor go bad and the engine died while i was driving it and wouldnt start tiill it was replaced thats why i was wondering. I had to have it towed to the shop and stuff it sucked.

It with throw a cel right?

I thought it would be cool to see the numbers before and after the tune if it will run. Maybe stock, then with the CAI, then with the tune.

What is the order they have to be installed?

if you have a scanner you can watch the voltages bounce up and down. the stock ones pretty much have a Rich, Stoich , lean. but as for knowing the exact A/F no.

BowerR64 Does the LCD read anything from any of the o2 sensors?

If its changed to the wideband sensor would it do anything?

Thought it might be good to have more then one reading

I remember there was some readings the dash display posted that we didnt know what they were for.

Sorry if this is a dumb post like all my others.
It's not a dumb question. It would be nice if it was that easy.

AFAIK, there is no LCD readout in the scrollable odometer display that corresponds to any kind of A/F reading or voltage that could be used to compare with a separate gauge. The "odometer" diagnostic function gives data that pertains mainly to instrument cluster readings/sensors.

It is missing the key ingredient which is the wideband sensor in the exhaust flow - an O2 sensor won't do - which generates the voltage read by any gauge.
