Altitude. In understand that the altitude readout isn't adjusted for current pressure, but still. Mine reads 687 ft when I'm actually at 14 ft. Is there a way to adjust it so that it's al least close?

I wouldn’t be concerned about this – density altitude could easily differ from actual altitude by that much.  Mine was much further off; but then I have some discrepancies on other readouts that are still puzzling me.

Warnings. The system sends an intermittent ground to flash a warning light. If you're using a voice system or a LED that flashes anyway you'll need a steady ground. So, instead of saying "John, Check the engine monitor" my voice system says "John...John...John..."

Is it a sexy female voice?  Maybe she is just overwhelmed . . J  Can’t comment on that one; don’t have a voice warning, but the flashing LED seems to work - although it has been flashing all the time.  I haven’t checked all the warning settings, but I assume something has always been out of range.

I also notice that the offending item on the display flashes about once every 30 seconds. I find that this is too long. If you miss the first flash you have 30 seconds to wait until you know what's wrong. I'd rather see this flash set at every 3 seconds or so.

Hum-m-m.  I recall that mine flashes with the LED; at least once/second.

Anyone else have any tips as I head into this calibration stuff?

My experience so far would indicate that you should check the calibration on most or all channels.  That would mean verifying readings at least at two points; low end and in operating range.  I had air temps and MAP readings that were a consistent 10% off using the default calibration inputs, although when Tracy had the unit in his shop it apparently was giving good readings; so there must be something that is installation dependant; maybe just mine.

As I was getting into the calibration stuff a couple of weeks ago I managed to trigger some obscure bug (some combination of inputting a correction just as a low voltage warning was triggered) in the software that resulted in corruption of all the calibration data on a half dozen channels.  Unfortunately added to Tracy’s concerns while Frances was dealing its blow.  But a new chip is on the way, so I will resume that journey soon.

Meanwhile, my rotor oil injection pump was leaking oil around the adjustment level shaft and stopped pumping oil, so I had to exchange that.  I thought that little Mikuni (sp?) pump was bulletproof.
