For our customers running a car with no way to capture speed, this Haltech speed input module is be the perfect piece to your puzzle.

An example would be if you are running a NA/NB Miata with our ZF5 or ZF6 transmission and a Haltech ECU, you'll need this to see vehicle speed.

Note that this unit cannot be used to provide a speed signal for auto blip downshifts or traction control.
