uno turbo 1.3L digital tacho (instrument panel)

I buyed from ebay a uno turbo digital tacho (instrument panel). I noticed in my old device i had a tube coming from turbo to the panel, but this digital panel have no place to stash the turbo tube inside. my question is, how can i make/adapt the turbo tube to work on the digital instrument panel. i think this digital panel receives electric impulse from turbo, not like the old one which use a tube for readint the turbo presure. Thank you in advance for your answers.

I read somewhere before that you have to wire it up to a special pin on the ECU.

Re: uno turbo 1.3L digital tacho (instrument panel)

surely there would be an additional sensor? like a map sensor measuring the vacuum pull and relaying that as a signal to the digi dash?

Re: uno turbo 1.3L digital tacho (instrument panel)

the digital dash has no vacumm input, just block it off, all you need to do is connect a earth wire to a the black wire on the back of the instrument panel and it all should work apart from the digital boost,

for the digital boost to work a wire from the instrument panel needs to connect to a wire off the ecu, dont ask me which as i dont know, i myself have a digital dash and am trying to find out how to wire the digital boost

Re: uno turbo 1.3L digital tacho (instrument panel)

In Haynes it's a wire that is marked: "Turbocharger operation waring light"

Is this the wire that is going to the digi dash , it's not connected to anything, in the manual.

It's pin nr 22 on the ecu.

Re: uno turbo 1.3L digital tacho (instrument panel)

I don;t have the manual. Could you just make a picture of the ecu and of the pins there, and point the pin it should be connected to the turbo instrument panel ?

Thanks !

Re: uno turbo 1.3L digital tacho (instrument panel)

apparently its pin 22, but which wire it goes to on the digital dash is another thing,

I've attached a picture of the ecu for you, if you do get the digital boost to work will you please post up details for others so we all know how to do it.

Re: uno turbo 1.3L digital tacho (instrument panel)

as i promiced, only mod you need to do to make the tacho / instrument panel work, is to connect a -12V ground / masse to the black wire in the back of the tacho ( there are 3 wires, black,red and white). then is powered on and work everything except the turbo presure. i hope i'll figure that out too.

Re: uno turbo 1.3L digital tacho (instrument panel)

Yes the digi dash needs a wire taking from the magnetti marelli ignition ECU as it has a MAP sensor to adjust ignition timing built in, Its not the turbo warning light pin tho, The haynes manual only covers Analogue dashes, you will need an original fiat manual to find the wire to the dash input but off the top of my head I cant remember which pin it is.
Good luck mate.
