(T) Questions about the digital dashboard

Hi everybody ! I have the '89 1.6 DOHC Tipo, with the digital dashboard... I wanted to ask a couple of questions about it, in order to solve some things I have with the panel signalization... My first question would be about the two "econometer" lights... as you know... there is the GREEN one (identifying ECONOMY) and the RED one (identifying POWER) ... so... I noticed that the GREEN light is ON all the time the car is working... and it never goes RED even when I rev the car to a high RPM limit... It just doesn't switch to POWER signal at all... (I have checked the bulb, it's working fine) ... It always stays GREEN, showing the ECONOMY mode... So, I wanted to ask you for the advice, how could I solve this thing... and also, if someone could tell me... What is the correct purpose of this mode ? ... Does it just informs you about the fuel consumption level, depending of the style you drive your car... or there is something else ? ...

... And the second question about the panel would be... I think the fuel level gauge just isn't working... I bought the car with the LPG (autogas) system installed, so I use it much more than the petrol drive, because of the fuel prices here... but I saw this problem since I put the fuel several times by now... and the fuel level gauge just showed nothing... It constantly shows like there is no fuel... with the little red slash blinking on the upper left... so... I suppose this might be about the little buoy, or the swimmer (sorry, I don't know how exactly to say it in english) that measures the fuel level in the tank... I'd like to hear some suggestions please... thanks !

The solution for your firist question is bord computer which you must put on comp or the lamp in orange colour is out, which is most ussuall on this car and for the second, solution is to put a new buoy in petrol reservoar, course J have once a same problem.

ive a code reader diag thing for one of these never used it, got no instructions, but can take it to a meet if any one knows what to do with it
