Not sure quite where to put this question as it covers a number of Fiats.
Most fuel injected Fiats have a charcoal cannister along with a series of solenoids/ pipes between the fuel tank and the inlet side of the engine. This is to recycle petrol vapour and stop it from getting into the atomosphere.
Basically what I want to know is this. Will the ECU from a Punto 75 SX (mk1, 1996) run with the solenoids disconnected from the evaporative emission system? The reason I'm asking is that I am hoping to transplant an MPI Punto engine into my 1986 mk1 Uno. Being a 1986 carburetor model it doesn't have much in the way of emission control and by law is not legally required to either. As it doesn't have any emission stuff fitted it will be a pain in the butt to have to transplant all the Punto emission stuff into the Uno when it doesn't need it.
Also, some of the early injected mk2 Unos (of which I will be fitting an i.e. fuel tank into my car to take the Punto fuel pump) just vent to atmosphere anyway, so I might not even have all the take offs for the emission pipes.
But will the ECU throw a wobby if the solenoids are disconnected? Or will it run happily without them?
Hopefully someone will know!
