Hello all,

My name is Adam , thank you for taking the time to read me first post i'm hoping someone might be able to help me....

I have hit a information blind spot and was hoping some one might be able to help with filling in the gaps for me.

for the past few months i have been in contact with various companies regarding the rear ABS sensors for my scorpio 4x4 as they are like hens teeth! i have disided to purchase 3rd party and have custom types made , but they require a hugh about of information i was unable to get to them straight away, i set my self a task of finding as much as i possibly could, but findin such information regarding fords abs sensors are almost impossible even ford techies dont seem to know as all i got was laughed at down the phone!

i think i found out that the sierra xr4x4,cosworth and other abs models use the same treves abs module and ecu which in turn use the same sensors as the granada but ever so slightly longer (well this is what i gather)

the things they require are the following.
target speed in rpm
what is target made from
target air gap
target tooth count and Diametric pitch

but i have no idea how to calculate the Diametric pitch ?

thanks for reading

regards

Adz
