New install of the fast XFI. All power and gound connections are good and the ECU shows to be powered on. Made an adapter to allow connection to the cal port connector on the fast harness. Red wire from fast harness to pin 3 of the comm cable, white to 5, black to 2. I have double checked this cable, also made another cable. I've tried two different computers, one that required a USB adapter and another that has the DB9 comm port right on the laptop. Regardless of what comm port I select in the fast software or in the device manager of the laptop I cannot connect. If the fast is powered up and I try to connect I get incompatable device error. If the fast is off I get ECU not found. I'm using the 1.340 version of fast software and was loaded from different sources on each laptop. On the compter with the USB ports and driver it works fine connecting to my MSD box, as does the old laptop with the DB9 comm port. The fast ECU was recently tested.
