To me it sounds exactly like the Gauge that sits at full for 1/3 of a tank, and then drops like a rock. The ECU uses the other table to know exactly how many gallons are left in the tank. I kind of wondered how they did that, it would be neat to see what the factory tune had in those tables and if they were the same also it might be that the gauge isn't linear so the idea is to try to make it so the gallons line up with the line on the dash.

the spyder posted:I’ve got a 2HP Teco FM50 you’re welcome to try, but I think you’ll find the same problem under heavy load. Many of those older motors are just so severely over rated, modern VFD’s struggle. At least in my experience with Bridgeport pancake motors, surface grinder, pedestal grinder. We switched to a rotary phase converter commodore64 built and haven’t looked back. VFD's are rated for 2 HP worth of current. with almost no overload, like 130% (depending on duty of the VFD). - looks like that one is 7.5A? FLA of a typical 2 hp motor at 230 is 6.8A, so only 110% torque. Across the line motors can easily give out 6x rated current for a small amount of time, like startup. So you will see motors that could easily work when they were directly connected, and then you put a VFD on it, and it no longer works. As you had 12 HP worth of torque (when you slow a motor down, the motor current increases to get back up to speed) for short bursts, before the overload would trip. You can get the same performance out of a VFD if you size it for the max current instead, and then set the motor parameters in the VFD. The VFD will know if your motor's getting hot, and trip out on Overload.
