Now based on the latest stepper motor technology, it can be switched for input pulses per mile/km and features an LCD odometer with resettable trip function

and this is the sender for it

M16 x 80mm lon


i take it its just like fitting a digi dash,but is that the right size for a F13 gearbox?

p.s i have no idea

Sounds like it just runs off an electronic pulse signal.

That sender is nothing like what fits in a GM box tho.

As above, thats a bit newer electronical one, you want the old crappy magnetic mechanical one! Lol

Yeh just need the mechanical driven one i think, ive never really looked much behind my dash but im guessing as its a pretty simple car it would be the mechanical driven one if your really interested in using and eletrical one i think the new astras use electrical type speedos??? I dunno?! Lol

[Adam]

Some corsas, tigras etc use electronic speedos.

Basically they just run off a speed transducer same as what a digidash uses.

Easy peasy. Dan runs one, he just mounted the sender unit via a custom bracket he made to the gearbox, and the magnet attached to the inner CV.

Although that magnet looks heyowge!

do they pass mot tho?
