K Series ignition with Weber DCOEs

[Mikey UC]

I started a project a while ago replacing my Ford Crossflow with a Rover k series but still using the weber carburettors.

The old crossflow used a webcon 3d mapped ignition which I was told could be remapped for the k series.

After quite a lot of bovver the engine was installed, the carbs connected and the engine fired up and idled (although a bit lumpy) on the old crossflow map.

 

I then contacted Northampton motorsport to arrange for the ignition to be remapped and found out that my unit was one of the early units that cannot be remapped.

 

So – I was about to splash out on a new Omex unit, it will be about £450 but will have the advantage of using the rover crank sensor and not having to tow the car to Northampton to be remapped.

 

But just before I did I was just wondering if anyone had any other suggestions for a Rover ignition system running with weber carbs.

Many thanks

I can't help you with this but if your looking to buy an omex ecu maybe we can ask for anti y bulk buy through Raceline ?? Cos I would like one too

Would it not be possible to run the standard Rover ignition and ecu, with a Rover engine loom?

 

I'm another Xflow to K Series convert, but I spliced the Rover engine loom into my original harness, and installed a Jenveys/Emerald setup.

 

I can't see why you couldn't run a Rover ignition setup, which I believe can be mapped/tweaked to optimise the ignition advance?

EU2 ECUs cannot be remapped, EU3 can.

Thanks Oily! There you are, either way (EU2/3) defo worth considering for ease of install, using Rover parts to look 'factory' and available anywhere, and you'll have an easy optional upgrade later to (tried and trusted) Jenveys/Emerald combo

I hadn’t even thought of using a standard rover ignition, only problem I can think of is wiring it up to the Weber throttle position sensor, and then calibrating it

The engine I have is an EU2, so I am currently using the Weber coil pack, but I guess the EU3 engines have their own coil packs.

There is a K series ecu pack on ebay for £70 but I’m not sure if its EU2 or EU3

Emerald every time!

plus 1

EU2 K series with single coil and dizzy + Webers + EU2 loom (with redundant injector, stepper motor wiring removed) + emerald + RR session for ignition map, cam timing and jetting.

I'm sure you'll be able to rig up the Rover tps to the Weber butterfly spindle using an adaptor from Trigger Wheels, or even Webcon themselves ?

 

If you don't want the expense of an Emerald right now, I'd run the Rover ecu, but definitely have your carbs set up on a rolling road

 

Give us an update when you get sorted!

This takes me back - this was what I had planned to do with my in 1994 when I first built it! Ended up taking the easier route of a Zetec. Good luck!!

Thanks for the advice gents.

Would love to go for the Emerald but it’s a bit out of my price range.

Think I’ll stick with the Omex, as I know it will work with the webers and my existing wasted spark coil pack.

Hoping the thing will be on the road this summer.

 

Will keep you posted
