Trouble Data Logging TPRT and APU1

Figured I would try some data logging via the instructions that were included with my APU1 and no luck.

I downloaded the 6e datastream definition from TunerPro, converted the ads file to an adx file using TPRT, plug in the aldl cable, hit the connect button, and I get a flash image on the dashboard but no results. Says DA Connected with no errors, at 0.1 Hz. Try to reconnect over and over and same result over and over.

Tried changing the position of the switches, outboard away from USB, inboard towards USB. When I switched the inboard towards the USB the engine started running funny though, idle went up, got rougher than normal, and when I bumped the throttle it took a while for rpms to drop.

I was attempting to simultaneous emulate and datalog.

I did a search but did not come up with this specific problem, as I am using the ALDL cable provided by Craig, and everyone else issues where with home built cables.
