Rpm Signal Level Converter

[boostn0199]

I have a turbo timer which says it needs a 5V digital singal from the tacho sinal to operate and if it doesnt have it needs a RPM Signal Level Converter . does anyone know if the r33 tacho signal is 5v digital already? or do i need the converter

What sort of timer is it? I know with my timer (Greddy FATT) that I have it connected to the Vehicle Speed Sensor signal from the ECU which is pin 53. Vehicle Speed Sensor signal is basically engine rpm's. I've attached a screenshot for you if it helps.

Good luck.
