Digital dash, Technical bod question
Discussion
Im not a fan of renaults in any way, I do however like the concept of a digital dash display in my wedge.
So, Adam Q, RCX, Wedg1e, and all the other technical bods out there,
How easy would it be to interface the below from a renault into the aperture of the 350i wedge dash?
would they have a control module for each input or would it be a complete ECU for the control of inputs and outputs?
Your thoughts?
Im also looking at APPS for the insertion of a mini tablet type unit into where the stereo and switches are housed, something that would have outputs to control/ switch relays for lights, fans, hazards (with mech back up) and the other bits that are on there! havent found anything yet though!

From its configuration that looks like it's a LHD car or are they all mounted with the instruments in the middle?
I think it'll be a nightmare wiring that in and I imagine that you'll have to use their sensors and ECU which would be a difficult integration job. Can you get hold of a technical service manual to give you a better idea of what you'll need to do?

It would be a nightmare, as I believe they use CANBUS to communicate with the body computer, engine ecu and anything else they deem fit to communicate with it 
Would be a cool touch if you could get it to work tho
The alternative is a digi dash from a mk2 Astra gte or even a 24v Senator, as they are just normal car electrickery to get to work

24V beat me to it; CANBUS aside I'd expect it to get some of its data from the engine management system and that probably not in an easy-to-replicate format.
Even the simpler stuff like fuel level could rely on a sensor that produces a response totally unlike the rheostat in the TVR's tank... I know I had a 1986 Renault 25 and that used a resistor ladder to give the fuel computer sensible information.
Nothing's impossible of course but by the time you adapt what you have or build interfaces you may as well start from scratch and do the whole thing... probably all easy to do with PIC chips , Raspberry Pi or whatever.

OK apart from all the eletrickery problems the thing looks too long and I doubt if you could just saw the end off and it would still work!
If you're going to canbus all the sensors you'd probably need to get them all from the scenic too. But while you're at it why not do away with the wiring loom and have one big power bus going round the car instead.

the only mini problem I have is adapting the speedo drive to the gearbox.
What's the problem? Mechanical or electronic?
Has anyone tried Stack? http://www.stackltd.com/dash_displays.html
We used this on Formula Continental, which was not a sophisticated engine.

Some cheap all in one digital speedo's here maybe you could convert a mini one to work?

most gauge manufacturers do a transducer that has a speedo drive cable input and outputs digital signal, not sure if you can calibrate these to any speed per revolution though.
I'd be surprised if you couldn't. I had a digital gear indicator on my bike that sampled the speedo and tacho pulses and, once you'd told it which gear you were in at setup time, it knew the relationship between speedo and tacho so could work out what gear you were in at any speed/ rpm... so a simple pulses:speed calibration should be a doddle.hallsie said:
So, the first problem will be getting a pick up from the engine for the Tacho, any thoughts?
Hi mate...What about a "Road speed sensor"....Most modern cars use something like this which is linked to the Speedo...ABS...etc...http://www.google.co.uk/url?sa=i&rct=j&q=&...
Maybe something like a trigger wheel or pick up..Could be wheel mounted?..Crankshaft?...Prop?...This is where i get lost sorry....
Ziga
Some ideas...
