But i have fitted a lpg system with max regulator, super-max (yellow) injectors and the other system parts are compatible with them (thicker parts etc). Because without them there will be some performance problems, this system can cope with up to 40-45 kW per cylinder. |

I have the 2.0l engine in c4 picasso, thinking of either a Bigas or Stag Premium system at moment... |

Most of the cheap ones are using selonoid valve type ınjectors, they aren't suitable with some car brands who have smaller gasoline injection times (around 2-3 ms), citroen are also using this type of system on gasoline. So it is important the lpg system you will buy have injectors like keihn or brc injectors, If you but lpg system with selonoid valve type injector there can be some problems at AFR when idling or some performance problems at road. |

That looks cheap - I wonder how easy it is to retro-fit. | ||

I take it back as this was posted over at C6owners: rogerandoutman wrote ... Be very careful with an emulator, I fitted one to my Avantime with an lpg conversion. All they do is cut power to dashboard and fuel computer, so the fuel guage resets. Mine decided to cut in on the autoroute in France, I lost all dashboard functions, indicators, brake lights ect. Just managed to pull off safely. Had to remove the unit and resplice the loom. Later on just fitted an interrupter switch, which I just used to cut supply for 30secs, this allowed to fuel guage to reset to the actual petrol amount in the tank. When I contacted the Italian manufacturers, they just suggested to try a different model emulator, even though I had purchased their recommended part. However as outlined above, an 'interrupter switch' sounds like a simple plan. |

Anyone still interested: After my LPG conversion: When my gasoline tank is in the last quarter or less the fuel indicator does no reset and I get the low fuel gasoline warning. When I refill the tank only for a couple of liters it resets. When I refilled the tank to 3/4 or more indicator the fuel level resets every time I turn the ignition on. So no need for special modules and whatnot. Just fill up the tank and the car will recheck the fuel level every time you restart the car. |

Hi! when the fuel tank is lower than 3/4, solution is to refill tank only with couple of litres (even 1 litre?) It seems like, fuel tank has to be more than 3/4 all the time, not to experience this problem anymore? Stankoman wrote ...

Thanks... rgds, Sascha |
