Calling any car electronics guru,s on here?

As others have said, yes it's possible.

You need to know what the ecu is expecting in terms of pulses/rev so you can match a sensor. Some cars have the sensor in the gearbox so it's multiple pulses/rev of the wheel. Some take signals from the ABS system.

Not sure of the details on the universal system - it might be able to simulate different pulse signals, however if it doesn't then there are speedo correction boxes that'll convert it to something the ecu will understand.

Possibly the best mod I made to my landy was power steering. I understand why you want to do it.

im still trying to work out these bits and the wires where they all go?

the black box has 7 wires

voltage knob 2

and is that other plastic bit one of thoses cable clamp on blocks like on pc monitors or car radios to stop signal interference?

Puzzling why you have a pot. Pots generate a variable voltage, I'd have thought (assumed) the ecu wants pulses.

But then you've got only 2 wires on the pot so it's a variable resistance. Most puzzling.

is it you clamp the black block at the top of the picture to or round speedo cable, then bolt on the black box with 7 wires and this monitors movement inside the speedo cable?

and the knob is just to set power of steering so only needed to set once and forget about it.
