As you may remember i posted up about possibly ditching the omex 600ecu and going back to p8, so ive spent the day removing it all and inspecting it, and i was horified at the engine loom!!! crips, solders, loose ends

but the things that struck me was no knock sensor or speedsensor, and only one earth on the fuel rail!! can some one fill me in on if all ecu systems need a knock sensor, where is it ment to fit, on a escort cosworth and same with the speed sensor, in the omex handbook it show them.

cheers

Sounds like you have a 500 series ecu.
Knock sensor isnt used on them.

A knock sensor isnt mandatory on ecu's !

Neither is a vehicle speed sensor. Unless you mean engine position sensors?

seems strange as there shown in the handbook for it i'm just trying to get to the bottom of my problems!! i have plugs coming out in different colours! some lean some rich but at complete random!! with massive backfires accasionly.

another thing i noticed is the lamba sensor heater live was taken of the injector lives and aparently they have a big loading!! that could be a problem!! making the injectors have different power.

Sounds like your loom is a complete mess!! A new one from Omex was only about £220 last time I had one.

do cossies have knock sensors?i cant remember my old saph loom, i have got a plastic sensor thing going around the speedo cable as it enters the casing, i think that may be a speed sensor.

I don't run a Knock Sensor on my 600 either. Not a great amount of people do.

Sounds like its been installed and mapped shite more than anything.
