Wot Sensor Is This

[jaimo]

Is it cam posistion sensor

[tractor]

i think it is a vr type sensor but i am being told that it should be a hall sensor

oh and by the way it is my camshaft sensor off of my st170 engine if it is a vr sensor then my my ecu and wiring loom have got to go back to be put right if this is the case then i am not a happy bunny not i repeat not a happy bunny

rage boiling inside !!!!!

[jaimo]

The crankshaft sensor on st i believe to be hall

[jaimo]

I do believe that sensor to be a vr as dont hall effect have three wires and vr 2 if i remember correctly

[Longboarder]

Im pretty sure its a VR sensor. Only two wires and its strongly magnetic. One of the good things about Omex ECUs is they allow the user to move a simple jumper on the motherboard to select VR or Hall effect. I would be surprised if whatever ECU you are using doesn't allow you to do the same. VVTPro expects a VR sensor.If your ECU is happy to batchfire the injectors and uses wasted spark then it doesn't need cam position input.

the ecu is setup for sequential firing so it needs a cam signal plus i already have the mtech vvt controler which uses cam sensor yes the ecu can control the vvt but it just on or off at a certain rev

[tractor]

the crank sensor is definatly a vr and i think cam is to but the guy who has supplied my ecu is saying it is unusual for a vr cam sensor to be fitted on a zetec st170 personally i have yet to come across a ford engine fitted with a hall sensor

Oh no

[tractor]

Don't worry andi he has told me how to change the ecu to a vr sensor

[theduck]

Ms3x has more than one VR conditioner anyway doesn't it? So should be an easy change.

[Longboarder]

Good that ECU can be easily changed to read VR sensor. I'm interested to see if the cam change controlled by the VVTPro brings any changes to the sequential firing of the injectors. Possibly yet another complication.

My ST injectors are batch fired by omex so it don't read the cam, just the crank but my VVTPro which I am finishing the install of tomorrow will read the cam(and crank and TPS). Fiddly making up the wiring loom. Those Molex connectors are diddy.

Yes possible complications ahead but the ecu can control the vvt but just on or off at wot revs you set it to

[theduck]

You have an ms3x don't you? If so that can do continuously variable VVT control

[tractor]

yes i have the ms3x on reading through the blurb there is nothing i can find apart from on off vvt
