I have installed an mgl e1 engine monitoring gauge and it is outputting the rpm way higher than what it is. I’m comparing it to a tiny tach. It’s pretty obvious that the mgl unit is wrong. Tiny tach says 3000 and mgl says 4000...mgl says 9000 and tiny tach says 5000 for example. Mgl said to adjust the rpm sensitivity put that doesn’t change anything. I have verified the wiring is correct and grounded as per the manual. Also settings are correct per manual and mgl. It’s on a rotax 582. Do you guys have any ideas for me to try?
