So I wired up an Subaru vtps to my Miata ...it works alright but I'm not sure if I wired it right to megasquirt , does anyone know how to do it . /9 far I wired it up to the stock loom and re wires it like dig auto tune said I have diypnp by the way ...I did tps to 4l and vref to 1n

 

If you get a reasonable range between the open and closed ADC under Tools -> Calibrate TPS, then it is wired properly.
