I have landi renzo injectors, so far 170 000km without problems(turbo engine). With original landi renzo piggyback, they fall around 80 000km.
---- Well couldnt stay away, Med (thats what landi is using) injectors can last for ages when mounted correctly. The membrane will wear and tear when the oilofin can build up inside. seen injectors fail in 30.000 km and seen them last for 300.000 km with the landi system. It all depends on how its fitted. A second note is that med injectors are pretty linear, Just like keihin, hannah and aeb injectors. Matrix could work to. In general piston injectors tend to not respond linear to pressure changes. Thios is due to port opening becomes harder compared to membrane or needle injectors. Hanna and keihin are needle types. The others membrane. So after some thinking those more expensive injectors are easier to setup then the cheap valtek injectors and their clones. Valtek isn't bad at all but they wouldn't last 200.000 km and a pressure modified map would like linear response. The lpg pressure sensor has a second really nice option. empty tank switchback, High pressure warning switchback and fuel line break switchback. Would work if the shut-off valves are controlled by a second vems port in true bi fuel setup. (so you can switch while driving.) Its also that I wouldn't like to see al the shut-off valves opened when driving on petrol. Gives some issues with the reducer compensates pressure under high boost but cant loose it after you stop the car. Could lead to lpg leaking in the intake. I didt quite a bot of lpg modifications and really agree letting vems control lpg is the best option, if the bifuel rom is done properly. Specially concerning the safety. With bifuel there is a risk that a lpg leak occurs while driving on petrol. Closed shut-off valves would prevent strange accidents. Just don't underestimate the lpg pressure and temperature sensors as a safety feature. I once fooled a temp sensor by clients request. He fitted stronger hoses after his vapour hoses bursted due to a pressure spike. It resulted in a broken membrane and liquid lpg found a way in the vapour system. The results were interesting but did do some damage and costed quite a bit due to the fire truck that investigated the lpg leak. Dinand Broekhuis |
