I'd guess you're looking for the crank sensor.

is it the crank sensor does it control the rev counter?

I think the rev counter is driven by the ecu, the crank sensor tells the ecu where the engine's at. I can't see there being the traditional Hall sensor if there's no dizzy.

The crankshaft sensor lives by the flywheel. At the top to the rear I think. Might have to take the air box out to get to it

ok cheers guys so the crank sensor might be messing around as the rev counter goes all over the place
ive taken out the clocks and soldered every joint so its not them
ill try cleaning the crank sensor next as the car doesnt start properly too

I think you've tried all the obvious areas Dave, I'll have a fish around and see if I can spot anything from when I was researching it.

All the diagrams I can see are exceptionally vague as to its location

I can tell you it's part 1920W9, costs £23.26, and that it sits in the engine somewhere around the flywheel's circumference. It appears to have its 3-pin connector mounted on a small bracket a short distance away from the sensor itself

I'd go and have a nose, but I don't own a tubby any more. Also it's too cold
