Dynon Dudes: I have been on the annual tour of the US to visit relatives and friends, 32 hours in 15 days. Today, I noticed that the top half of the "P" in "PSI" fuel pressure was flashing on the D100. The lower leg of the "P" was fine but the upper half was flashing. The "S and I" were fine. I checked the "PSI" symbols on the D180 and the symbols were fine while the "P" on the D100 flashed. What do you think is the problem? Dan.
