Shift lightAfter having drive the car on the track and even sometimes on the road, I was looking for a shiftlight, like the turbo ones have as standard. After browsing for a bit, I found one with a little more options than standard. Allthough they market it for motorbikes, it works very well on a Speedster.
This is the Datatool RevLight. Main functions are:
I was having a go at the electronics of the Speedster today anyway. So with the dashboard allready out, I could start mounting the RevLight. It needs four connetions:
For the RPM pulse, I could tap into the connector running up to the stack unit. You need the white wire with the black stripe. I stripped a bit of the insulation away, and soldered a wire parallel to it.
After that I taped the wires back together, so we had a neat cable once again.
Now for the last wire. As I have installed a couple of buttons on the stalks
earlier (see the move horn project) I used one of those to control the RevLight.
When putting the dash back together I mounted the RevLight on top of the Stack hood. Did that with double sided tape, so got some ductape over it at the moment of taking the picture to alleviate the pressure on the double sided tape to let it set. The nice thing is that the RevLight has a flexible housing. So it will follow the form of the Stack hood.
When everything is installed you need to calibrate the RevLight. First
hold the engine at idle and push the button. Next run the engine at
4000RPM and push the button.
Ofcourse you can trick the unit into different rev ranges by callibrating at a different RPM then the 4000 stated in the manual.
When driving the car you have 3 modes of operation:
When driving at night the unit really works well. The autodimming is really VERY good. Light is low enough not to be distracting, yet it is very clear when you need to shift up.
