Using a free ignition output for TACH signal to my old instrument cluster (which usually is fed from the coil)


- 5x 680 ohm resistors

- 1x 220uH coil (from rescue kit, black in shrink sleeve, looks like a barrel and has both connection pins at one end :-)


Not sure yet.

For the moment being I am considering postponing this until I upgrade firmware to 1.1 branch and can use VEMStune + 7" touch screen as instrument cluster replacement.
