hi,im replacing the cvh with a 2.0 zetec and running it on twin 40s webber.
i dont know what i do with the wiring though,im not the best when it comes to this field!!
what do i need to do or buy to get the engine to have a spark????i have a low budget though!
cheers for any help

 

Just run all the original zetec ecu+loom..

 

will it not read a fault on the ecu without all the connectors and fuel injection rail connected?

 

The only thing that wouldn't be connected would be the injectors and MAF.. technically the ECU will be running on a base map (due to the MAF being unplugged), but it'd be more than adequate for simple spark control.

Any early 92-93 ECU & loom from any zetec-engineered car would be ideal..

 

cheers for that,so i just replace the loom complete in the car and do away with the old one?

 

Well no, you're gonna have to make them work together.. The zetec loom won't need much more than power from your original loom.. and the tacho output.. and fuel pump perhaps..

 

right,ill probably be back on here for advice pretty soon wen i cant get it to run!!

 

your better off using mk5 CVH stuff as it runs carb and coil pack,no ECU stuff to mess with

 

how do i do that then,does it all plug straight onto a zetec engine?still good to use the 40s?

 

if you get an esc modual from an early fiesta (mk3 1.1 for example as long as its got a coil pack not a dissy) ) this will use the standard crank trigger from the zetec and a vacume line plumed into the inlet for the advance and they are realy easy to wire up

 

i'm pretty sure you can run the ignition system of a like 89-92 hcs fiesta/escort, they have the vac pipe on the edis

 

the 1.3 stuff dont rev properly ive been told

 

would it just be easier to get an 1.8 zetec from the mk5 xr3i and run it on that loom with the twin 40s?

 

if u can find it!but it is easier just to use the mk5 carb stuff,neater to

 

how do you mean the mk5 carb stuff?is the zr3i mk5 not on a carb?ive never had one i only ever kept myself to the mfi xr3i?is it just a stamdard mk5 escort 1.8 or is it a smaller engine?

 

they done a 1.4CVH mk5 escort with a carb,well,single point injection, but it runs a coil pack,the looms really basic and easy to wire in

 

oh right,so i just dont connect the single point injection....well therell be nowhere to connect it anyway,it wont run badly or nothing without all plugs connected then?cheers for all your help!!

 

the banger boys use it and they run and rev sweet,hence why i know the 1.3 stuff dont rev right!

 

its not edis it esc to compleatly different systems

 

It's ESC-I, the predecessor to ESC-II on the escort rs turbo!
