Help please

Post by locust7 »

I am building a kit car which has a Ford 2.0ltr DOHC engine in it, I have built the MJLJ and it is speaking to the pc as described before. I would like to know if anyone has used the original fitted crank wheel, which is just in front of the flywheel, as I have not stripped the engine down I dont know how many teeth it has and where the sensor is in relation to it.

Can anyone help please?

My email is bb_wales@hotmail.com

Thanks

Bob

I have no clue my friend, I asked for you in a place that builds 2.0 DOHC, dont know if I will get a response. I suggest you look for "focus forums" on google, join forums and ask a question. Ford Focus had a 2.0L, and they know about old 2.0L engines. So you'll get your answer plus you'll adversite for Megajolt. Good luck, and post the answer when you get it.

If it is a 2.0 Zetec it should work correctly. The required 36-1 pattern is part of the flywheel. AFAIK you just need to connect to the existing sensor.

I assume you mean the front-engined, rear-drive 2.0 twink from a Sierra, rather than a Zetec?
If so, note first which way the engine turns when running. Then slowly turn the engine forwards by hand until you get No.1 TDC. Now look where the missing tooth is, in relation to the VR sensor - it should have already passed the sensor (90 degrees ago) in the direction of the engine's rotation.
If this is correct (it should be), plug the sensor in and you're ready to go. If not use a couple of levers against the pulley to remove the trigger wheel, turn the engine to TDC, then back 90 degrees, line up the missing tooth with the sensor and lever the trigger back on.

If the engine came out of a ford car with either EDIS ignition or EEC-IV (which has the EDIS in-built) it will have 36-1 holes in the back of the flywheel and the VR pickup will bolt through the engine flange that bolts up to the bellhousing.
this sensor is usually down one side of the engine near the bottom.

The Holes are square(ish) and make up a pattern that equates to 36-1 teeth of a trigger wheel.
you have the ideal setup here because you will have perfect VR sensor positioning and will not have to worry about centering and attaching a custom trigger wheel.

Very few UK Fords came out with a trigger wheel on a pulley on the front of the motor where the whole setup is able to get coverd in road grime. most had the flywheel machined as above and kept the triggering mechanism nicely hidden away in the bellhousing behind the flywheel

Ford invented EDIS and the more modern integrated ECU variants and are unlikely to have changed the spec.

aftermarket ECUs often use wheels of more teeth these don't tend to use an ICM like an EDIS module.

if you connect up the EDIS and coils and connect up the power and sensor and the car starts everything is OK
it does not need to be connected to the Megajolt. it will run quite happliy at a rock solid 10 DBTDC (ideal if you plan to run a turbo)
if you have the wrong number of teeth the car won't run.

I belive all FORD motors spin the same way. Its GM odd fire v6s you need to watch out for
