Is it possible to create a display in the cluster screen for the stock wideband sensor reading? I'd sacrifice the "average speed" tab.
Anyone try something like this before?

I guess that it is possible.
You can't simply add some menuitem, but you can "abuse" the radio (music info) part of your cluster.
So you must block the radio canbus cmds, and send your own. This has done by many people before, do some googling and you'll find some examples.
You can even buy complete units which will do this for you (show sensor data on your cluster display).

Thanks for the info. I did some searching and all I could turn up were a few companies selling "magic boxes" that get plugged in to the factory cluster harness an the cluster $$$.
Is this setup the only way to accomplish my goal? I was hoping there would be a way to reprogram the cluster software to watch a different input (O2 volts) and display the numbers.
Is a hardware interface necessary?

Yes, you'll have to build a box for it..
However, with the rise of cheap, programmable SOC kits (arduino, raspberry pi etc.) it would actually be a pretty straightforwards DIY project if you know your way around CAN.

Cool. A friend of mine is an engineer and does arduino all the time. I'm going to ask him if he'll help with this idea. If it works, I'll post back the project
Thanks for the info!

im using local mfa-box which connects via 3LB wires to the cluster and displays some info on top section like a boost; coolant; speed; IAT etc also it has a vag-com GUI and can read any engine info by groups like an original vag-com, its not hard to check group 31 for current lambda i believe you can find something like this in US   |

The circuit diagram?
Building something like this with Arduino would be cool; I'm curious now too!

fis control didnt stop his busines, polarfis is another alternative but they all are expensive. start here: http://secuduino.blogspot.de/ |
