Question: Does this mean I can put the unit back on Amp.Rem power instead of constant power?

Forgot to answer this. Yeah, it should be safe. Basically the optimizations should put the Zodiac in the same mode it would be in if your automaker had mounted the unit in the car, at least if I understand the documentation.

Initial tests seem to indicate that I must leave the receiver fully powered in order to get the fast-startup benefit. I'm still curious about finding out how much current it draws and whether I'm going to drain my battery with it.
