Ex-Finesse Posted August 25, 2005 Share Posted August 25, 2005 i thought id just plug mine straight in without swaping wires and it ran fine which was strange <{POST_SNAPBACK}>It's because yours is an early mk5. Wiring is different, exactly how I don't know. Fuel pump wire is something to do with wire 1, as I tried this first and it didn't work. Personally, I'd try an ecu from a manual 2L mondeo. Everyone else has had a 2L ecu working fine apart from you 2 guys, and you both have auto ecus. Link to comment Share on other sites More sharing options...

foxdie Posted August 25, 2005 Author Share Posted August 25, 2005 cant see why i should need a 2.0 ECU. every thing is 1.8 apart from the bare block Link to comment Share on other sites More sharing options...
Ex-Finesse Posted August 25, 2005 Share Posted August 25, 2005 cant see why i should need a 2.0 ECU. every thing is 1.8 apart from the bare block <{POST_SNAPBACK}>But the cylinder capacity is 2.0L..... so you need the right fueling for 2.0L of air. The fact everything else (apart from fuel rail / injectors last I knew) is 1.8 is irrelevant Link to comment Share on other sites More sharing options...
ryanrs Posted August 25, 2005 Share Posted August 25, 2005 Keeping the 1.8 ecu on a 2.0 engine would give the same effect as puttin a 1.6 ecu on a 1.8 lump.. great if you want to restrict the ammount of standard power it can give. it would in effect be the opposite of superchipping!

ANDYC Posted August 26, 2005 Share Posted August 26, 2005 cant see why i should need a 2.0 ECU. every thing is 1.8 apart from the bare block <{POST_SNAPBACK}>not sure if ralph drove his with the 1.6 stuff on but i drove mine on 1.8 stuff and it felt good but then i fitted 2.0ltr stuff and it was loads better specially a top end Link to comment Share on other sites More sharing options...

foxdie Posted August 26, 2005 Author Share Posted August 26, 2005 Im using the ib5/1.8 flywheel. The crank sensor was the orginal 2.0/mtx75/automatic sensor. Link to comment Share on other sites More sharing options...

Stu Posted August 27, 2005 Share Posted August 27, 2005 changed the crank sensors over. No change <{POST_SNAPBACK}> Did you also change the crank sensor mount? Link to comment Share on other sites More sharing options...
sorted_mk6 Posted August 28, 2005 Share Posted August 28, 2005 right, just a quick suggestion, dunno if this has already been mentioned, aint got time to read.......... mine had same prob wen i fitted the xr lump.try.........the crank sensor, unplug it, cut both wires n reconnect them the wrong way round, did this to mine and never had a prob since. i had to pay £50 to get that done! might not work but worth a try Link to comment Share on other sites More sharing options...
vampire Posted August 29, 2005 Share Posted August 29, 2005 my car was turning over but not starting, and after replacing: whole loom.all plugs and leads.new starter motor, new ecu. it turned out to be the ford inbuilt alarm, if your clock is flashing when you put hte key in and turn, then its activeand you need to lock the car passenger side.

No change <{POST_SNAPBACK}> Did you also change the crank sensor mount?<{POST_SNAPBACK}> i changed over the sensor but not the mount. Must admitt, i wasn't happy with the wayt the sensor sat in the 2.0 mount. but it went in fine. Its at the garage now, so lets see what they say.

Let me get it up and running, then i'll worry about fueling Link to comment Share on other sites More sharing options...
