5 volt tach signal from subaru engine

[prvpilot1]

I am trying to hook my subaru engine up to the dynon flightdek 180. The tach signal from the ecu is 5 v. I found a ATSD(adjustable tach signal divider) that converts the 5v signal to a 12 volt signal. I know the manual says that it requres 10 volts for tach. Will this converter work to hook the subaru up to the dynon?

Hard to say. It needs to output a voltage pulse which both goes above 10V, and goes down to ground.

it outputs a 0 to 12 volt signal from the 5 volt signal from the subaru ecu. Sounds like that will work.
