Latest spec LPG installs use a seperate set of injectors, and their own ECU and a "bypass" to fool the factory ECU into thinking it is still working. Older systems just used something like a carburetor to do the same thing, and just tricked the ECU with the readings it was getting, rather than bypassing it. The C900 turbo, and all FPT 9000 models are too advanced for the "Cheap" LPG conversions that tend to be setup for carb and early injection systems. Later models need modern setups. It just need a more careful setup of fuel to air and monitoring with LPG. You can even get vehicles that can run 100% of the time, even at startup on LPG, because the system pumps it as a liquid into the engine instead of petrol. Once started it returns to pumping it as gas, and the engine runs as a normal LPG run. -- Carl Robson Car PC Build starts again. Homepage:
