I need to borrow (or potentially buy) an RTek, PowerFC (with adapter), or anything with logging capability that can be used with the stock harness and sensors.

Also interested in an FCD to eliminate the possibility of fuel cut.

I'm troubleshooting an s4 tII, possibly on the dyno tomorrow, and it would be nice to have something I can play with / log, rather than probe ECU pins one at a time.
