i have traced a problem with my tickford lpg set up (vialle) on my au2 futura wagon to an intermittent signal problem to the stepper motor .
Can any one provide a wiring diagram of how the gas system is wired into the main loom?
I have replaced the stepper motor with new ,rebuilt the converter ,checked for continuity on the connections in the engine bay.
currently running without the stepper motor and a blanking plate in place ,runs fine like this just a bit rich.
Does the gas have a separate ecu?
any advice appreciated
cheers
