Guys,regarding the speedo drive.
Is there anyway of getting a signal from the abs/speed sensor wired into the clocks?
I’m a mechanic and I’m going to go with this 6 speed conversion for both of our a2’s,but I need to know if it’s possible.
Thanks and keep up the good work
Another way would be to use an electronic interface. I assume the gearbox has a reluctor ring (or actually a gear’s teeth) and the sensor is the reluctance type, or else the gearbox has magnets and the sensor is a Hall type. If one knew the number of teeth or magnets on the gearbox speedo “drive” and the same for the ABS reluctor rings, then it should be possible to do it with the required level of accuracy. The most flexible way would be with an Arduino linked to suitable interface circuits on input and output. Another way would be with a linear frequency-to-voltage converter circuit driving a voltage-to-frequency converter to give the right multiply or divide factor.
A fair bit of trial and error would be needed, and if I had the time I’d offer to help.
There is the advantage that no new gearbox has to be bought or fitted before a custom electronics converter box is proven.
