Ever since we installed our GRT Horizon HXr, we've been getting a low pressure warning. Often the display actually shows a NEGATIVE fuel pressure, which -- since the engine continues to run, happily -- is obviously bogus.
Then, when I turn on the electric fuel pump, I often get a warning for "fuel pressure too high". Again, nothing changes in the engine.
Meanwhile, the fuel flow indicator seems correct. It will blip up a bit with the electric pump on, and blips down a bit when you turn it off. It behaves logically with throttle changes.
The Horizon gathers engine data from/through our old EIS 4000. I don't recall this happening when we had only the EIS, but, frankly, the data presentation on that instruments was so poor, who would know?
I've tried changing the settings in the Horizon, to no avail, so I'm assuming that I either have a problem with the sensor, or I'm going to have to change something in the set up of the EIS.
Anyone seen this? Any advice in what/how to change in the settings?
