I was just wondering - is this right :
with a cold engine the ecu advances ignition timing and keeps the injectors on longer (riching up the mixture) this is the old equivalent of a choke.
the reason I ask is that LPG needs an advanced ignition timing as it burns slower - which would explain why the car runs better when cold.
or is this just a load of old cack?
secondly - is there a way to fool the cars ecu into thinking that the ignition has been advanced? eg. the engine is always cold?
