Title: Waterproofing or moving ECU
Post by: blacknight on July 10, 2006, 23:51:29

Is it posible to waterproof or move the ecu to a higher position to stop the ingress of water.

I need to do this asap so any methods or ideas will be much appreciated.

In fact any ideas for waterproofing a V8 Range Rover, or even making a home made snorkel(photo's or a diagram please) would be of a great help.

The vehicle is a Range Rover 3.9 V8 1992

Thanks

Most if not all the connection for the ECU are made via the driver's footwell so I think you can move the ECU and related relays as one lump to wherever the cable will reach.

easy job, remove the ecu and relays from udner the seat. Pull back the footwell /tunnel carpet to access the ecu loom, unclip the loom and pull back the cable. Mount the ecu under the dash at high level and hold in place with cable ties. I mounted my latest one to the right of the steering column inplace of the small cubby box. Ive also mounted it in the centre of the dash above the radio in the past but putting it to the right of the steering wheel theres more room and it easier to get at.

You need to look at Hang Over you do :wink:  :wink:

Machine Mart do a nice line in convoluted plastic tubing off the shelf which will give you a snorkle for about £20.00 (coupled with a 45 degree downspout elbow for over the roof)

(Hang Over's Snorkle is a Rebel series 3 one upside down!!)

Once you have moved the ECU and sorted the air side....silicon the dizzy cap on and fill yer boots (literally if it stops!!)

Thanks for the replies.

It's given me quite a few things to think about, especialy the snorkel.

A good set of leads,  Clean the dizzy cap and coil before fitting with a VERY light smear of vaseline  

Smear of grease around the joining face of the dizzy

See avatar.

A snorkel will be my next purchase though as I do not have shares in the company that makes the air filters

Thanks for all the replies.

ECU has now been moved to the top of the dash.

Easy job to do. Took out drivers seat to gain better access to the ECU. Unscrewed the ECU and pulled back the carpet to reveal the ECU cable. Then unplugged and unclipped the cable which was the re-routed under the dash and out throught the little panel in the top of the dash. Stuck ECU to top of dash with double sided sticky tape.

Sprayed plug leads and dizzy cap with motorcycle chain wax but have not yet found enough water to test these waterproofing measures yet.

try a hose on the engine electrics. Hopefully you won't need to test how much water you can fill the inside of the car with before the ECU starts playing up!

The lunch box suggestions isn't a bad idea. We do that in our racer.

I think that Scorpion Racing do an ECU extension lead.
