My mate that built it wrote a program to operate it. Taking the pulses from the gearbox sensor and converting it to motor speed to spin the speedo cable to the appropriate speed. This is fully calibrateable via smart phone.
I'm just on with fitting another MTX75 in the car at the minute then as soon as lockdown eaes the box of tricks will be fitted.
It's been fully tested on a test bed using a pulse generator.
That is absolutely brilliant! Would you make another set to sell, if so, what would this cost?

Thanks Mate, i have a MK1 Focus RS box at the moment, so I might go down this route too. Do you know what other models used the older style bell housing? Sorry, just to be clear, did you end up using the MK3 fiesta speedo and cable or MK1 focus speedo and cable?
