I went through Moates directions to test the ALDU1 as seen here http://support.moates.net/datalogging-with-an-aldu1/
It passed with a message saying cable found and operating. But when I connect it to my obd1 port and click 'Acquire Data (connect/disconnect)' it says connecting at the bottom of the tunerpro screen and stays that way never making the connection.

I've tried setting it up to different com ports and tried messing around with settings and switching from open to 10k on the ALDU1 switch but nothing makes it work. I also have good working drivers for it, the same drivers run my Ostrich 2.0 just fine.

The car is a 1990 Corvette with 1227730 ECM
