Heres a pic of the transducer. Depending on what car you have, you might be able to use the Corsas own speed sender to sample the pulses from. I used the original Corsa one in mine and the speedo is accurate. I got clocked by a speed camera at 38 and the speedo read 38 too:lol:

I am also wanting to fit a digi dash to my corsa. Can you please send to me aswell a pic of the transducer......
I have heard that that you must use the speedo from the astra as if the original speedo from the corsa is used then the digi dash wont read the correct speed........is this true?

Also were about on the gear box do i find the speedo?
Cheers;)

I've mailed a pic of a transducer to the address in your profile. Its too big to host in my garage and I don't know how to resize it.
If your car has an electronic fed speedo, you may be able to get away without the transducer. Mines electronic, and I use the Corsa one for my speedo.

ttt

cheers, where do i get the transducer from? or should it be with it? what does it look like?

Nothing "needs" to be modified at all, you can fit the complete digi dash as it is, although because it is rectangular it will leave gaps in the curved Corsa dash space. See above, all you need are the two loom plugs and the transducer.

what needs to be modified on the dash? also is just the digi dash and the sensors all i need?

Not too difficult, the finished result will depend on how much work you put into it, although you can fit it in a couple of hours.
<<< Thats mine.

is it a big job?????

yeah will have a look at it if i see u down there, when u normaly go down?

dont need ecu, but do have to modify the dash surrounds to get um fit. aint finished mine yet but if you want a look u might see me down fes in red sri with vectra sri wheels on

right nice 1,may have to purchase it. how does it need to be modified to fit the corsa dash?

You need the dash (obviously), both the black and white plugs from the rear of the dash. Try to get a good length of loom attached to the plugs. You'll also need the speed sensor (transducer) from the top of the gearbox, again, get as much wiring as you can attached to it.
Fitting is relatively straightforward, depending how you want the finished item to look.

never heard of the ecu thing before, fairly straight forward, i think!

been offered a digi dash for £30 out of a astra gte with all sensors for fluid tanks etc. do i need the ecu? been told i do but arnt sure? also how easy are they to convert?
