So once I got my 2056cc built the tach could no longer keep up and just flailed around worthlessly... Especially when running an autocross. So I finally got around to trying the 2200uF trick and now it's over damped... Sigh. Maybe I'll try a different variant of capacitor and see what happens.
Anybody else have a recommended type of capacitor for the application: http://en.wikipedia.org/wiki/Types_of_capacitor |

I'm not sure if this helps (free advice, take for what it is worth). I jumped a resistor to get the tach to accept the signal from an EDIS module. It also worked with a the tach out line from an SDS ECU. I haven't measured it but, I suspect both of the fedds I used were 5V.
