right i no theres alot out there about wiring up the zetec i have a 1.8 silvertop EEC-IV ecu out of an 1998 escort gti i have most of the loom and im thinking of stripping the loom down to the bear essentials i have key and transponer i have the pin out diagram for it but wondering if any1 no's whats needed and wots not!.im not using the injection as bike carbs will b fitted. was going megajolt or emrald ecu do use the original too? any help would b appreciated.

Hi,

On my build I used Megajolt to save the problem of making/modifying the original loom. Megajolt is used by itself and has caused me no problems and I am very pleased with the install.

+1 for mega jolt they sell as a zetec pack with all the bits you need and a basic map for around £200

thanks guys so what your telling me is have no need for the loom or ecu and the megajolt will replace it all?

Hi,

Yes that is correct.

Bob

im so relieved cos looking at that ecu pin out digram and loom my head was scrambled thanks again guys! i always get the answer on hear i posted it on haynes forum first few days ago but no1 replied! can always count on the locostbuilders for answers!!!!!

Not sure if I will be correct, but you are using a 98 reg engine. Will the car not need to have a CAT fitted, will it be OK without if say you get a Q plate.

I understood it to be a pre 95 reg engine was OK without cat po9st needed one. So if running Megajolt with carbs will it be OK?

Edit to say noticed not saying a 98 engine, just a 98 ECU.

98 should be eec-v and has 104 pins.

And if there going begging for not much dosh let me know

I'm pretty sure a cat wouldn't effect it but I may stand corrected! I'm thinking Of fitting one just incase anyway, The escort gti was P reg 98 and the ecu is 60pin and has eec-iv written on it, the only reson I went for the 98 was that it was a gem of a find on 8000 miles off a mate of mine.

If your putting the engine in a car that will be IVA'd then it will need a cat and in my opinion will need injection to meet the test.

Some say you could get the engin through on carbs but I doubt it.

Ultra low miles that, not even run in.

I have tested a zetec on carbs with an eec-v but only as a complete loom. Never did try and see what the min amount of sensors are.

I am guessing

crank
Tps
Ect

Like most 3d ignition ecu's

Cam phase
Lambda
Maff

Will be needed for injection aswell.

o right i do have two sets of throttle bodies wich i was going to use before i changed my mind as i thought it would b more complicated to set up i even have an st170 manifold wich i was going to use for them, im not to sure now! im not to fussed about fitting either but am worried about wiring it all up and was keen when i heard all i need is the megajolt kit to get the carbs working on the zetec! am i right in saying that if i use the tb's do i still need the loom an ecu cos im not feeling to confidant in setting that up myself! i have even thought of changing engine to cvh just for iva but having the zetec in and fitted and engine mounts made, i feel as if im going backwards if i do! aswell as having to cut out the engine mounts wich im very pleased with!
