Waterproofing Megasquirt?
As winter approaches, I'm getting ready to officially start installing my turbo build parts. I want to start with installing MegaSquirt; I know the OEM ECU is fairly protected by an elevated brace + carpeting and soundproofing, but the MegaSquirt mounts a little differently. I'm concerned about water getting to it; I've already had one A/C hose clog that resulted in water spilling into the passenger footwell.
I'm from Montreal and we get a fair amount of rain as well. Am I being paranoid about wanting to waterproof the MS? If not, what have some of you done to ensure your $1000 ECU stays dry and safe ;p ?

You can use a Singular (or homemade) bracket to mount your MS in the OEM style, slightly elevated from the sheetmetal and protected by the cover and carpet.

IIRC, in a 1.6 the ECU is under the passenger-side carpet, I could see it getting damp there in the event of a leak.
To waterproof a non-pro megasquirt you basically need to encase it in a waterproof container and then seal the hole where the wires come in somehow. Theoretically you could do with a gasketed box and a bunch of hot glue around the wires, but it's really not practical. If you really care, you'll have to buy an the pro and put the waterproof connector onto the factory harness.
You're being paranoid. If you were building a Locost/Exocet/Catfish/etc style of kit car, then this might be a real concern when driving the car in the rain. A race car that has compromised waterproofing and needs to be reliable in the rain might also be a concern.
