Durametric Experts - Can I read codes with engine out of car?

[nuvolari]

So I have my new Durametric and yet I'm still several months away from having the engine back in the car but I would love to read overrevs and cam deviation and other error codes or problems right now and so my question is if this is possible? I know I would have to install the ECU, reconnect battery and then turn the ignition on and probably other things too. Is this possible without damaging the ECU or any other electronics? Or is this even worthwhile? Are there any other things that might be relevant and good to know before I reinstall the engine? Or should I just wait until it's back together and running again?

Car is 2000 986S, 6 speed manual.
Durametric is Professional version.

Thanks.
