Hi, I would like to know how can I use FSUIPC to toggle APU switch on/off (using the same button) on FSX. I can't find the suitable offset to indicate whether APU is on or off. I tried using offset 0B58 (if i can remember on top of my head). When APU is off, the offset value = 0. But when you turn it on, the offset value = some high number and quickly count down to 0 (based on log reading). Is it suppose to do that? Eric
