Natural Gas instead of petrol

[Marek Niemand]

Hi
No way it will work. 
The ECU is programmed to make injectors deliver just right amount of fuel at
right time for every possible load/speed point.
In principle lenght and timing of an electical pulse to injectors spill
valve controlls this.
That in its turn is dependant on hydraulic behavior of the injectors and
fuel system.
So, besides the mechanical conversions including special tank,valves, pipes
and so on, you would have to remapp the entire ECU.
It is much easier to convert carburated engine.
