    Erratic Oil Pressure

    I second the motion... I tried fixing the grounding issue to no avail. Just ordered the GRT sensor myself to put an end to it.

    Power On Alarm Status not working

    I've got to appologize as I obviously, once again, failed to interpret the manual correctly. I guess I didn't see the word "all", in that "all" of the conditions must exist. The "power on alarms" are definitely turned off and it works as advertizes. I realized it last night after flying...

    Power On Alarm Status not working

    I have the same issue except I also get the alarm bar on the screen and have to acklowledge 10 or so alarms every start-up. The noise in the headset is the only thing that is canceled.

    Fuel flow sensor Factor

    Thanks! I guess if I just read the installation manual again I would have known this. I don't see that there would be any air bubble issue and yes, I believe it is far way from bends.

    Fuel flow sensor Factor

    I have a similar problem with my fuel flow reading and I assumed it is because I have yet to calibrate my left fuel tank (a sendor issue that I just haven't had time to change.) I have an IO-540-K1E5 that should be in the 13-15 gph range in a cruise RPM/MP setting. Going off memory here, I...

    Oil Temp Fluctuation

    Thanks for the reply. I do have a wooden airplane. I will check the engine ground lug, because now that I think about it, it may be painted. However, why are my CHT/EGT readings so stable? Are they not as sensative as the oil temp?

    Oil Temp Fluctuation

    I have an EMS-D10 installed on a Lycoming IO-540-K1E5 and show large fluctuations in oil temp readings. I've seen as high as +-40 degrees, but usually in the +-20 degree range. I'm receiving fluctuations on the ammeter as well (+-4 amps). All fluctuations occur within a half second. All of...

    Manifold Pressure Indication

    First a question and secondly a comment... I just finished installing an EMS-D10 and noticed a 0.5" to 1.0" differential between the manifold pressure indication on the unit and ambient pressure. For example, today at 925 MSL and 30.7" ambient pressure, the EMS inicated 29.8" when the engine...
