Hey guys I am looking for 1 or 2 1999 and up VWs that come stock with BOSCH wideband sensors. Since those cars came stock with Wideband sensors, the ecu has all the required complexity required to correctly control the sensors.

So here is my offer, all I need is to wire up a few things to your car for a hour or 2, only 2 wires required. I gaurantee that it will not mess up anything in your car. In return if the thing works, i will give you a completed wideband reader with the datalogging software for your Windows XP laptop. What I need to do is to tap into two wires on the wideband sensor it self, and I will not be doing anything to the ecu. If by any chance I damage the sensor I will give you a new one that I have on hand.

This is also open to any honda guys that own hondas that come stock with the NTK wideband sensor also. I am much more knowledgeable with the bosch LSU wideband sensor but most things should be the same with the NTK.

If everything works like I think it should then you will get a completed reader, if things do not workout like I think they should then I guess I will pay you 20 bucks for your time. You can watch me when I do everything to make sure I am not doing anything shady, but there is not much to watch since I will just be splicing into 2 wires on the sensor. I am an electrical engineer so I know what I am doing when it comes to electronics and stuff.

I am not selling anything, so this is not a commerical post, mods please do not lock this.

I am using a bosch wideband o2 sensor on my setup.

What "reader" are you using?

I am not after people who have an aftermarket wideband reader, I need people who's cars come stock with wideband sensors.

Okay here is the total story. I am building my own wideband reader I have 3 designs.

Design 1: similar to Techedge/innovate/etc products, I have already done this design but there are a million widebands out there, so I went to design #2.

Design 2: Wideband reader+Electronic Boost controller+iginition retard under boost control+Fuel Mapping(AFC)+Turbo Timer+EGT reader, all in one tight package. I have already designed each one of these before, but now I am in the process of integrating everything together.

Design 3: a special cheapass reader for cars that have ECUs already capable of interfacing with widebands. Although the ECU uses wideband sensors, it does not display them to the driver so the driver does not see his true AFR, so it is useless for tuning. I have a simple way to get the AFR from the sensor as long as the sensor is properly controlled by the ECU.

So basically I need help with design #3, in help I need a 1999 and UP VW since they came with BOSCH wideband LSUs.
