I am looking at making a crossflow engine distributorless.
Any ideas on a simple ignition only ecu, and what sensors I might need.
Running on 40's

Thanks

If you wanted to go the megajolt route, I have an MJLJ brand new purchased from triggerwheels and used only to check that it works and a weber throttle pot kit that I am willing to part with due to a change in plans.

Megajolt and trigger wheel on the front pulley.

what about the ford EDIS system, they were often fitted to the valencia engine (ford Ka ) which looks like the Kent cross flow

You'll also need one of these http://www.locostbuilders.co.uk/viewthread.php?tid=105792

iank, not a problem with that, I have a lathe.

I have done some more research now,. Am I right in thinking with the Megajolt you still need the EDIS as well?

What with the special plug leads, wiring loom, sensors etc, it isnt a cheap job is it???

Well I am still researching this, and have come to the conclusion that Megajolt with the seperate EDIS unit is likely to be difficult to trace a fault ie which box has failed!

I am all for reliability, and that is 2 boxes and more connectors, and then unreliability!

Does anyone know of another ignition only system where everything is all in the one box?

The beauty of the MegaJolt is that it uses an OEM quality ignition module, carefully designed and rigorously tested by the manufacturer and well proven in millions of cars around the world.

The EDIS not only takes care of the coil switching and dwell control, it also integrates the time/angle conversion which means that the engine will continue to run even if the Megajolt box dies (albeit at the fixed ignition advance).

If you think the Megajolt is going to be too expensive, then you probably need to re-align your expectations. Any commercial system is going to cost significantly more than the MJ (e.g. Omex 200 £345, DTA S40 £420, Weber Alpha Bronze £575).

megajolt and edis is very cheap concidering what it is if you buy all the bits on ebay like edis and vr sensor

next step down i think is the electonic dizzy kits that remove the points and replace it with hall effect pickup but you are still stuck with your dizzy ignition curve

our pinto started with points which were about had it so bought an electronic kit which did exactly what it was supposed to flawlesly but have since upgraded to mjlj and its so much better to start and drive around its like a whole new car

The engine will be modified quite alot, so want to get the best out of it. With a disy, the advance curve is always a compromise.

If you are in rush look elsewhere, if you are not my mate builds them. I ran one for years on my racecar, he is working on one for my crossflow at the moment, but due to his work, he gets little spare time to do his hobbies. Fully mapped via laptop, all in one unit, required only trigger wheel and sensor and coil pack. If you want to get the best out of one, air temps and intake airflows can be fitted.

Anyway, PM me if you want more info.

I have come across the Canems unit. Anyone got any experience of this one?
