While out driving to pickapart today, was playing with the trip computer to see my instant usage, etc
I changed over to LPG and the Trip computer is telling me HOW MUCH LPG IM USING???
Everything cept for the REMAINING K's is working on LPG.
How is this possible? The LPG has a "Feedback" LPG Computer connected to it in the engine bay and is wired into the engine bay. The LPG was installed only in '99 So is this possible?? I mean when its on LPG, you cant here the injectors so its not like its pumping both in. Has anyone else had this? Had me and john_xr6 stumped

in earlier cars, the ECU still operates the injectors when in LPG mode.. theyre just disconnected. so what the t/c reads is what fuel the ECU is thinking its putting into the engine. all 3 falcons ive seen on aftermarket LPG have operated this way.
It's not actually working mad_Ea_spac. Like galapogos said, the ECU stilil reckons it's feeding fuel to the motor so it's still doing all it's little calculations. The DTE, Inst. Ave. Consumption and Ave. Consumption all work off the injector pulse wire on the ECU.
