anyone using one?i need to know how many teeth on the chopper wheel and any probs with temp/fuel gauges on the dash/what senders are used etc 
i gave the guy a ring, he said the 36tooth wheel on the zetec woudl work but i asume you could set it to anything?
the only problem ive herd about with them is the fuel sender but there are work arounds for it. give them a ring on the mobile number tmrw

cheers peeps,how do you calibrate the speedo?
ive made a mounting point on the nose of the diff and spose i can use the 4 prop bolts as choppers?
Speedo calirated as standard to circumference of wheel, but if you mount the magnet on the prop you need to take into account the diff ratio...
I am going to mount my magnet on one of the inboard rear CV joints which allows you to attach a bracket to one of the bolts used to hold the diff
on.

mr monkey,does that mean you measure the wheel etc and set some switches etc?
Speedo setting done by typing in the circumference of the wheel in the settings menu.
