Nice one Robin!

Electrical faults can be such a pain in the arse sometimes.

Obviously OK for dry use and garaged cars, but all-weather cars are going to have problems I think.

Not all Honda conversions will have such problems.

So what is your solution then? Do you keep the MFRU, or do you use standard relays in a better enclosure?

As ever, I wasn't slagging off the Honda, just noting that the Sinc's conversion using the Hondata ECU doesn't strike me as particularly weather proof. Is the Jude variant fully ruggedised and weather proof?

Cheers

The conversions are standardised now, the Honda ECU is converted to a K100 via a daughterboard, then programmed with the map that has been developed for the Kit.

As far as I know, it is not waterproofed at all, but mine has given no problems over the three years.

I just got back from Robins who helped me sort my under tray problem. Unfortunately its back to MMC to get the heat shielding looked at....again!

Neways, cheers very much indeeed!

Hi Robin,

I realise you weren't slagging the Honda and I hope I didn;t sound too much like Scuffers jumping to its defense there.

Yes the standard MFRU is retained and the ECUs certainly seem to be waterproof enough. I

agree that the Sinclaires relay solution is not ideal but I would imagine it is done like this as it makes the wiring much cheaper. But maybe I shouldn't be saying things like that. We don't want this to turn into a SELCOCK type thread do we.

I am always just interested in the facts - I have no axe to grind either way.

That makes sense - I'll bet the ECU itself is sealed against the elements - the only other issue is the cabling - it's typical to have connectors/wires running down so that water runs away from the connector. When they face upwards (K-series S2, for example) then if you don't place a cover over the connector, water pools and eventually runs into the connections killing your ECU. Neil's ECU wiring emerges out the side towards the rear - problem is that S1 boots are often goldfish ponds and water evaporates and condenses and ends up everywhere

Once it's running again it might make sense to try and seal off the wiring a bit with some spray like WD40 or better yet a cover.

Cheers
Robin
