scroll down B13 from ECU

And you can find B13 by referring to the pinout diagram of the speedo cluster in the service manual on page 5097 to save you running a wire all the way from the ECU.

Ok, thanks guys, I've got it in.

Now dose anyone know what Hz per 10km/hr the speed signal is?

Thanks,
Paul.

No idea on that one, sorry. Are there fixed settings or can you specify an arbitrary value?

[08libertygt-b]

Its a brain teaser.

All it says is Setting range: 1P, 2P, 3P... to 250P
2P: 7 Hz per 10km/hr
4P: 14 Hz per 10km/hr
7 Hz for each 2P & so on.

So its fixed, but there's a lot of them...

No idea where you'd find that information... Trial and error always works though?

That's what I am fearing...
