My first P38 suffered that fate also. Water was over the bonnet. It took about 5mins for the water to get high enough in the cab to send the becm crazy, what I think did more damage was the relays in the engine bay being flooded. I got mine running again but it was not happy.
With the BECM overheating, you could always extend the small hose that goes to the vent between your legs down to the BECM box.
I used 3M gaffa tape ($25 a roll), and it worked perfectly. I rained in the proceeding few days and there was a lot of water in the rear doors, and it didn't leak a bit. I honestly feel like this solution would hold.
you could also install a boat sump pump, it won't stop the inevitable, but it may buy you a bit of extra time

A sealed tupperware box would give you a few minutes breathing space for the BeCM, and you would need to do same under the passenger seat for the EAS, TC and EAT ECU's. Then there is the SRS ECU at the rear of the cubby box.
From experience I can tell you that water certainly gets in through the drain holes in the doors, so taping them up is a wise move. It also gets in through the bungs in the spare wheel well. I am pretty sure it can get in through the transmission selector and the duck's bums on the a/c drain. Someone told me that there is a hole low on the firewall that lets water in too.
My thoughts are that the real solution lies in a manual kill switch mounted high on the dash which cuts power from the battery completely. Electrical stuff that gets wet can be dried out with metho and sunlight if it is not fused. Electrical stuff that still has power applied when it gets wet is less likely to be recoverable.
I'd love to see a TAFE project to relocate the low sitting ECU's to a box in the rear roof area. This would possibly be accompanied by a switch to kill power in the door and seat electrics, and the speakers.
The electrical sounds of my old P38 drowning in 2008 still haunt me to this day ;)
these things dont seem to let water in like other rovers, ive had min bout 8 inches up the windscreen, but didnt get bogged or stop moving, and had no water inside the cab. i would have thought it would have come in through the vents at the bottom of the windscreen but i might have just been lucky. a big emergency stop button on the dash, like used on earthmoving machinery, would probably be the safest option. if theres no power going through anything when it gets wet then it will be fine after it gets dried out.
