Going get it resealed later today after the conformal coating has dried then put a couple of silica gel packets in with it.

Good plan for the conformal coat (as long as it works before you applied it!) - else it's a pain cleaning it off with thinners etc

Silica bags will 'go off' if exposed to atmosphere for more than 30 mins - so make sure they're baked at 40C for 24hrs before you put them in there (but only if the ECU is totally sealed, otherwise they'll just absorb moisture for 30 mins & that's it.
