Tach for use with Megasquirt output

Recommended Posts

Ok,  So being a Newb to the 240Z scene and building mine up to be an autocross and track toy I am now looking at what to do about the tach.

 

So if money was no object what would you replace your factory tach with that still fits in the factory location and easily interfaces with the tach output from a MS3-pro which is a 12 volt square wave?

 

I have this thing pretty close to running now and am tying up the loose ends.

I use a later model Maxima tach and speedo with my Megasquirt. It is driven by the tach out circuit on the MS3X board. The speedo is also providing an input as well to give me speed info that allows boost by gear. You can also run the Autometer 5 inch tachs, but I didnt want to spend the $500 for the matched set. Any later model tach will work with Megasquirt. With the correct tach adapter, the stock tach will work with Megasquirt. If you are using only one coil, then it doesnt matter, MS doesnt have to run the tach.
