Duretec help
107eford - 29/11/18 at 08:11 PM

A friend of mine has a st150 fiesta duratec
Is it the same as a norm Mondeo 20l
I'm a zetec man so haven't a clue
Also does it run 31-1 crank trigger
With 90° trigger angle.
Many thanks Chris.

Yes and no.
Fiesta ST has a better flowing head
Block is the same except Mondeo has a dual mass flywheel Fiesta has a solid one
Trigger wheel is 32-1 tooth or 31+ a gap with 90 degree angle
Duratec don’t have timing marks and have interferance fit cam and crank pulleys
They use a pin to lock the crank at TDC and a bar to lock the cams

Essentially the same expect the head has been mildly ported in the factory and is known as a high port head. Not sure about differences in fueling and throttle body setup, though the fiesta single throttle body is quite restrictive. Bin the induction, fit itb’s and cams and it’ll give you 200bhp all day.

Thanks that's great
He's got megasquirt 1v3
Its been modded to run hall sensor
Not vr can the crank sensor be changed
For hall using the same trigger wheel.

So not the same as zetec 36-1
I don't no where I got 32-1

your right 36 teeth with one missing 36-1
Standard stuff 360 degrees, 10 degrees per tooth
Missing tooth is 90 degrees before TDC
Ecu does the rest

Thanks that's very helpful just need to no if we can change the vr sensor for a hall one as the ms is only wired and setup for hall.

Hall sensor is a strange one for ignition sensing usually used for speedo where slow speed sensing is important.
If your Hall sensor is magnetic then should work, temp range is lower than BR but you won’t get lower than -40 and you shouldn’t get higher than 150 or your car is on fire

just rewire the plug on your ms and adjust the pots to run the hall sensor my ms was set up to run a hall sensor and i changed it to run a vr
its all in the ms set up and wiring info

Cheers Chris just trying to get my head round it haven't messed with a ms for year built a few years ago and my early ms1 is still going strong in my car
If it hadn't been messed with it would be fine there's a few bits missing from the board where it's been modded so not sure if it's that straight forward it's for a mate just trying to sort it
I have got edis but need to find out how to get a pip and saw output if that's easier.
