Some assorted Pictures  -part 2

To get a decently calibrated speedometer, I bought a simple Bike-computer (Sigma Sport Terra) and fitted like this. Works great, now with lighting added. Also works as a trip computer, will show average speed and max speed for example.

This is the WIKA boost gauge, liquid damped and with a small "blue" LED at the bottom to light it up.
The red dot is the LED that lights up when the Saab APC system detects knock.
