Ok Im building up my Mk3 Fiesta with a 2.0 Zetec, It should only be a week or two from being ready to go but I'm getting a bit worried about if its going to work or not. Ive tried searching but I can't seem to find a conclusive answer.

The car has an RS1800 loom from front to back, and I have a DESK ecu from a Mondeo. Will this setup work or will i have issues with the ECU being internal EDIS and the loom having a connection for an external EDIS module?

 

BUMP

 

I think you need the loom to match the ECU - do a search as it's been covered.

As an aside, you may want to consider going OMEX or equivalent as you will need aftermarket management if you modify it a lot

 

a mate of mine had the same issue and im sure you need to change the loom..search for martinxr on fiestaturbo.com

 

Trying to find some of the posts on fiestaturbo now but I have to wait til an Admin makes me a member.

Have been doing a bit more digging myself and it looks like I can either modify the loom or run a 130 Spec ECU from an RS1800. Performance differences are meant to be minimal.

Oh and had a look at OMEX but its just not affordable at the time being. maybe next year. Thanks though

 

If you want to run a desk ecu then you need a internal edis loom from a fiesta si.

Although rs1800 management will run it fine.
