Quick Wideband Sensor Question Would the sensor replace the stock one, or would it be an additional sensor? If it replaces it, I guess it would replace the one on the exhaust manifold and still be connected to the stock Ecu???

 

good question, i wondered this myself.........

 

another question regarding this... question is applicable only if the sensor replaces the stock one.

Would the Ecu be dumping fuel more accuratly if it was connected to a Wideband Sensor?

 

i think you need to determine if the wbo2 sensor uses the same voltage as the oem one, then it MIGHT be possible to use the wbo2 one and splice the stock wires into that.......but i'm not for sure on that

personally, i say add another bung on for the wb, it might make it simpler in the long run

 

It replaces...unless you want to weld a bung on and have 3 O2 sensors. You could do that if you really wanted.

Wideband and UEGO units use a 0-5v output to accurately gauge the range of sensor output. Narrowband use a 0-1v output. If you hook the 5v up to your ECU it's going to take a ****. Most good WB/UEGO's will have both outputs. And keep in mind that, unlike your stock narrowband sensor, WBO2 requires a controller. So you can't just go buy a sensor, solder to a connector and expect it to operate properly.

 

like andrew said it depends on where u get it... some have two outputs to replace the stock sensor... and some just have the 0-5v output for their wideband controller/display unit. Just do you homework on the unit before you buy.

 

Make a third bung and put it in there. Most of the people that do use the wideband do that because most of the tuners that have tried to hook it up and replace the stock o2 say that it doesnt work. Plus alot of the widebands o2 sensors need to be taken out after everytime you tune. The sensor lasts longer that way.

 

It should work fine, even with stock ECU, so long as you use the 1v input to the ECU. If you give the ECU a 5v it's not going to undertand what the hell is going on.
