Hello
I am going to be fitting my Dash 2 (standalone, no DL) to my Nissan powered BMW and have most things figured out with the exception of the tachometer. The Nissan ECU outputs an open collector signal whereas (as I understand) the Dash 2 needs a 5 or 12v square wave input - would anyone be able to suggest the best way of converting?
Many thanks
Theo
Open collector tacho output
Pull Up Resistor
Assuming that there isn't anything else to the tachometer output. All you need is a pull up resistor to either 5V or 12V. The value depends on the tachometer output capability and the input current requirements of the dash 2. Unfortunately I don't know either of these.
