That EMU Black does look nice Dave. It’s an impressive bit of kit all round and the ultimate solution for any obsessive Morgan owning petrol head with an ECU. I’d love to have one but I know that I would just spend way too much of my life playing in the garage.

However, a Morgan with a Ford Visteon ECU’s is not so bad. A billion Mondeo’s on our roads is a testament to this well-engineered module, designed for longevity. It certainly lasted the life of those Mondeo’s but how long will it keep our Morgan’s running? Used for all the 4 cylinder cars with the Duratec engine and a 6 cylinder version for the early Roadster.

Even 20 years ago when this ECU was introduced it was using regular surface mount tech. If you need proof of its reliability just search the Ford forums. The only occasional issue worth mentioning was the susceptibility of the coil drivers to fail should one persist driving a car with a faulty coil pack. But even then, as luck would have it, a fried 5503GM driver was about the only component on the entire board that could be easily be replaced and they’re still just about obtainable today.

And the really good news is now that the donars have finished with them there is an abundance of second hand units around for next to nothing. So for an old dinosaur like me who just doesn’t think any car should have any electronics there is a fallback position, future proofing. I have to confess to having a small pile of these, the cheapest I’ve paid for one was the 4 quid starting bid... woohoo
