Not subaru related but need help

Hi my lass got a 98 Clio 1.2 8v but me mate who is a auto elec says there a short in a wire to the ecu. In theory the ecu fooked. So could a buy a ecu and just plug it in or will it have to be tuned to the car

may need the ignition key too if its a transponder key, ive just got one from scrapyard before and taped the useless key to the underside of the dash

Al try that but my local scrap yard prob won't have key lol cheers

If their is a short in a wire that is leading to the ECU isn't that also going to feck the new ECU also if you change it.

Not got a clue. That's a good point that tho al ask me pal

I would be very surpised if it has spiked the ECU. whats the exact fault ?

Not had it plugged in it kept blowing a 30amp fuses so me auto elec mate traced the wire and it leads to the ecu

Sounds strange, a 30amp fuse protecting the ecu, should be around a 60amp for ecu. It COULD BE an ecu fault but i would be doing a continuity/resistance test along the wire and make sure it's deffo not just a broken wire or short to live/earth.

As a say me pal looked and said every thing points towards the ecu. Damn lol

My dads had this problem it's a design fault there is a metal casing to the rear of they engine bay located on the bulk head my dads had snapped of and was cutting through the wires on the harness I removed the casing and mended the wiring dint happen again the casing covers two or three multi plugs if I rember correctly was a few year back now

Aye a no what casing u mean how dose that come off cant see how it comes off

I took angle grinder two it mate cos it was just hanging on the wires but solved problem

Ok mate cheers

No bother mate me dads kept going in to limp mode wouldn't go over 2000 revs and would blow fuse for horn and wipes and other stuff but after my little fixes was fine

I thought that only effect the 'newer' style engines, rather than the older type ?
