Electronic speedo.

Postby Adoom » Wed Sep 26, 2012 6:50 pm

So THE STARVIA has the factory starlet mechanical speedo. It is currently cable driven from the CA18 Nissan gearbox.
It reads 20% fast. The numbers only go up to 160kph, a bit useless if I want to know how fast I am going on the track...
I am replacing the mechanical drive thingy with an electronic sender, it's a straight swap.
I can wire this sender into the Link G4 so it knows how fast I am going, and it can log it too.
But this means the old speedo will no longer work...
If I plug a laptop into the link I can have a readout of the speed etc etc. But it's not ideal for normal driving or for WOFs.

The link can drive an electronic speedo with a pwm signal.

The question is, what electronic speedo can I use that is really cheap or free?
Ideally the doner speedo would not be part of a cluster, or be easy enough to dismantle and hack into the starlet cluster.

Looks far too flash :P Might go to Pick a Part and see if I can find something I can use.

On the subject. So I pulled out the mechanical drive thingy. It has a 24mm gear.
The electronic sender has a 28mm gear. but it just went straight in.
What gives? How can it engage? Am I being thick? :? :?

I've attached a multimeter(using the beep setting) to the wires and turned the gearbox output shaft, the multimeter beeps about 3 times for each revolution, so the gears are engaged.

i did a similar thing on a mates car which had a mechanical speedo but went to a electronic sender unit.

i just grabbed the guts of an electronic speedo that had the same sweep as the factory layout and made it fit into the factory dash. worked and looks stock as a rock.

This is the plan. I shall visit Pick a Part and pull some dashboards apart.
