Technical Uno turbo mk2 CATYLYTIC CONVERTOR

[Fiat uno turbo original]

Does anyone know if I can put a catylitic convertor on my uno without a lambder sensor?

You can, but why ?

Because last year when I done the mot the man said that the immissions where too high because it dosnt have a catylitic convertor so I am thinking of putting one . I asked ths question because a friend of mine said that you cant put a catylitic convertor because the lambder sensor had to connect to the ecu . but if you say it can I will try . thanks.

This sound odd. An ECU with a connector to a Lambda sensor that isn´t mounted ?
What Version and engine do you have?
After all it´s not hard to swap a modern ECU with loom into your UNO.

I have the 1990 uno turbo ie mk2 1.4

Well, then someone must have removed the catalytic converter.
I advice you to get a metal based one in order to keep the
gas-flow resistance low. Ceramic ones have a much higher resistance.

I have the very first uno turbo ie mk2 I know the last one had a cat I will put one . Thanks

Well I don´t know about your car.
Here ( in Germany) all models have a catalytic converter starting in the 80´s .
And that always goes with an corresponding ECU as that needs data from the lamda sensor to mix a proper fuel mixture. An ECU without a lamda sensor will go into an emergency mode and set the fuel mixture to an average level. This will surely not be done on a regular base by an automobile producer.

ohhh I see ok I will get an ecu from a different car get a lambder sensor and a cat . I will do as you tell me . THANKS

from what car should I get an ecu ?

 

[johorridoh]

From your model , what else.
Alternatively you can try a free programmable ECU like a megasquirt
