WTB: Wideband

[turbotalon1g]

I'll be a bit more helpful, but assuming you have a wideband already and you are just buying a new sensor you can find out what kind of sensor you have and possibly find a cheap one at a parts store.

Example? Most modern WB's use a Bosch LSU 4.1 sensor (IIRC) these are commonly used on VWs and can be had a parts stores for a lot less than most vendors.

So, we would need to know your brand of WB that you have, assuming you have one.

Although now it sounds like you need a WB that you can tie into some engine management.
