New to this forum, but I recently purchased a 2000 S4 with a slew of mods and a pair of blown turbos, and during the coming winter I will be installing K04's, fmic, stage 3 clutch with lwfw, maybe fueling, and full preventative maintenance.

Anyhow, I currently have a Innovate XD-16 gauge with a LC-1 a/f sensor and have been looking around their site at other options. I am really interested in their OT-1 ODB-II CAN interface.

Like VAG-COM (which I got with the car) it can display current info and log it, but they claim to be able to show and log much more data at once. It also can daisy chain with the other Innovate gauges and sensors so I can log from them, or display them on my gauges.

I read that it really only uses the common protocol and not necessarily the Audi specific, so it may not be able to read all the data available on the ODB2, so I am curious if anyone has tried it out?

Last question, since the car has a full dual exhaust, with just one a/f sensor could there be a chance of one bank running lean when the other bank is running fine? I could get a second LC-1 sensor and hook both up to my one gauge using this software they have developed. It would allow me to switch between the two, show the average of the two, or whichever is richest or most lean.

Thanks for the help.
