where is it mounted, if its where the original mk2 ecu was fitted you might find that the 2 water run off holes at the edges of the panel are full of crud hence not letting water run out.
Remove the ECU from the car, open the box up and leave it somewhere to dry out. Once it's dry carefully clean the circuit boards with a toothbrush and some isopropyl alcohol . Hopefully nothing went pop while it was running wet
