I4T, there are a couple of short cuts to setting fuel on board:
1. Go into config settings, and set your Main tank capacity to whatever you usually fill to, and Aux tank capacity to 74 USG less whatever you set for Main.
2. If you hold the right button a short time, it will increase the fuel on board slowly, hold a bit longer and it will run away as you describe. The same should happen on the way down: tap a few times and it will decrease one tenth at a time, keep tapping fairly fast and it should switch from tortoise to hare mode.
This works on the EDM 800 and 830, and I guess the 700/730 should be much the same.
PB, if out to save fuel/cruise far in my MX-7-180 I set about 58 to 65% power (say somewhere around 24"/2250) and lean to minimum EGT difference. This usually happens at about max EGT and results in smooth (for an O-360) running and about 28-36 lph consumption.
