Now that I almost have the Tecnam autopilot installation problems solved, I am starting to address the engine sensor problems. I have an oil pressure gauge which reads 50 psi with the engine off and 52 psi with the engine running. The CHT probs are not installed. The battery backup is reading 17 volts on a 12 volt system and doesn't display on the engine screen (only on the calibration screen). The fuel pressure sets off the high pressure alarm whenever I pull back the throttle to idle. I can't find any documentation on how to calibrate the sensors. Looking at the EFIS parts all of the probs are for the 3400/3500/4500 and sometimes the 2500 but don't mention the 5000 series.
