So after more testing on a separate laptop, I was able to get the smaller gauge USB cables to work and data logging in version 7.5 does not hang. It does however have USB 2.0 ports.

If I make the jump to using V8, the origional laptop combined with the larger usb cable works.

I just have to figure out making custom PIDs in V8. (if its possible using the Analog inputs yet).

On a side note, I saw where you should not use a car inverter to power the laptop while connected to the OBD2 port (knew about it already). Is there any problem with powering the laptop with its normal power supply plugged into an AC wall Outlet while on a dyno?

Also, prior to the 2nd laptop test...... both were revised to the latest Beta software that has the more stable USB driver for the V2.
