I have installed the EFIS D100 and the EMS 120 in my RV7A. When powered up, the EMS readings go all over the place. For example the Oil temp and Pressure fluctuate from low to high, the OAT and Carby temp are wrong, Half full fuel tanks show full, CHT and RGT are very high and the Amps fluctates. After a reasonable time, it settles down and the readings start to look correct except for the OAT. The OAT reading on the EFIS is correct. I have made sure the battery is fully charged and have tried with a battery charger connected, to ensure there is no voltage drop.
Today I successfully uploaded the latest Firmware package to the EMS and seemed to make no noticeable difference ie the wrong readings and fluctuations are still happening. When I successfully uploaded the Firmware onto the EFIS, it lost its connection with the EMS. It seems strange that the EFIS worked fine on installation, but the EMS doesn't. Would appreciate any help. The plane is ready for C of A so pretty anxious to get this sorted.
Thanks
