I'm trying to setup the fuel pressure sensor. If I set the maximum to 55 it turns red on the display, It will accept 50 without turning red. I'm setting the minimum to 0. I can set different ranges to different parameters with the last range to the top at 50 and the bottom at 45 with the color red. I'm still getting a fuel pressure warning at 38psi. I'm using the UL 130 hp engine in my plane. I'm pushing accept after each entry. any suggestions will be appreciated.
