I have heard that some autometer gauges operate on a 0 to +1v range but I also heard that some o2 sensors operate on 0 to -1v. Could my gauge be lying to me? It says lean but smells really rich and gas mileage sucks.

Ecu is chipped and programmed with uberdata. Anyone got any tips how to get stoich by changing uberdata settings?

 

You didn't connect the leads backwards, did you?

 

Get a wideband. Don't believe anything the narrowband light show tells you. It is impossible to tune a car without a wideband.

 

The gauge has a positive and negative and signal wire, im sure those are right. In the helms manual i connected to the wire on the o2 sensor that said signal wire I think my connections are right, just wonderin if voltages might be different than other cars.

I know i need a wideband but where do I find one and how do they hook up? Is a wideband just a replacement for the stock one?

 

Wideband kits are completely separate from the OEM O2 sensor system. They have their own sensor, harness and controller and will get power from the ECU wires that they are spliced into.
