If not, you might also consider switching from NORMAL to ENHANCED in the settings (comms section) and also slowing the rate of transfer (there is also an available option for this) which according to the programmers has been know to improve communication in some instances.

You may have something there. Although I have not had my engine running, I do remember that there was one module that I could not connect to in the configuration that I was in. I tend to think that I did not have the ignition on which is why I wanted to check. They cold also try to do it as you suggest with the engine running. I'm sure there is a voltage cutoff at some point.
