Thanks guys for all the shared information. Will be very helpful!

Any of you knows aproximately the lenght of the Lokar/Bouchillon cable? As I have to import it, so due to import taxes it would arrive here very $$$ so I'm thinking in doing it myself with some motorcycle throtle cable or something like that. Reading your information looks like it´s not rocket science.

Also, any electrical conversion every tried? I already have the position of TPS on my EFI (0V closed - 5V WOT).. so would be very easy to implement If I have the correct device to turn the valve (stepper, etc..)...
