I just finished this install, only took 2 weeks , lol. Let me be very clear about what I have not seen anyone else run into or comment on. This gauge is so precise that you better make sure your sending units are in up to spec. Older planes (like my 65 PA28) may need to have new or rebuilt sending units. I sent 2, 10 hour days trying to get this gauge to calibrate- Gave up, sent Sending units to Keystone for rebuild. Once that was all together, it took 24 min per tank and that was by myself. I suggest at least 2 people though! I cant wait for my first CC to really test them out, but this gauge seems rock solid!

Have not installed yet because I am waiting for the fuel tank sending units.

Unit is super accurate. Replaced the legacy fuel tank levels in a Cessna 150 with this unit. We ended up replacing the fuel senders as well since they were original and pretty much shot. None the less the unit is very accurate. Works great with a fuel flow meter.

Excellent units my 3rd one Im installing into my Pacers. Very accurate even if your senders are marginally accurate. No hardware issues after 5 years. Its expensive but I highly recommend this.

We installed this in our Commander 112 two years ago and it is a major upgrade to the accuracy of the fuel situation. Unfortunately the price has almost doubled in two years for the FL202 so I am not sure why as we would not have purchased at this price however it is a great piece of instrumentation !

After running a tank out of fuel with a fuel gauge indicating a little less than 1/4 tank of fuel left, I purchased the Aerospace Logic digital dual fuel gauge. It takes time to properly calibrate, but when I got it properly calibrated, it is right on accurate. If the gauge indicates that I have used 17.3 gallons, then it takes 17.3 gallons to fill my tank back up. I consider that my flying is much safer now.

Cessna 182Q with Cies Senders. Seems to be an excellent product, calibration was extremely tedious but well rewarded, and the install instructions were marginal. Dont expect to reach them by phone, youll have to use email. To be sure of not wasting precious time with fuel draining and filling, aerospace logic could give more specific and thorough install instructions. In hindsight, install was simple, but only after I had to ask specific questions. After all the work though, so happy to have an accurate fuel gage. Also, pair these with CIES senders, waste of money not to pair this nice gage with quality senders.

Unit is well built but very sensitive if using resistor type fuel senders. I have two of these units and ran into an issue getting the second one to work correctly. After many frustrating days of work I finally succeeded by running a ground wire from sender all the way back to same ground as the instrument. I was extremely disappointed in the customer service from the manufacturer. They left me high and dry. Stopped responding to emails and phone calls. I would have had a different opinion if they would have stuck with me through the issue.

Revised Review: After overhauling my resistive sensors, heres my observations: This gauge is dramatically overpriced. Read the specs, the accuracy of this unit is +/- 1 gallon, yet it displays in tenths of a gallon! Why? Useless, as it doesnt count down in tenths, it steps down, depending on what your sender resistance happens to be. You can only program where your red line gallons and yellow line gallons start on the bar graph display. You cannot input actual maximum fuel gallons. Since you program by 2 gallon increments, the final step is to add 2 gallons or to top of tank, which gauge will assume is 2 gallons. So, depending on your tank, the digital gallon display at near full is meaningless, and as fuel is used, youll finally achieve a +/- 1 gallon accuracy. Always follow the rule: Never trust your fuel gauge for accurate fuel remaining. Stick your tank before flight, accept the opinion of a fuel flow or analyzer type system, always err on the side of caution. Is this cartoon gauge better than the analog idiot version? No, its the same thing. Pricey graph display and ignore the digital gallon read out! That being said, if you utilize capacitive senders, your results may vary. (Completely different and Im sure more accurate by far) Consult with your plane doctor on which prescription is right for you! After purchasing the gauge, overhauling my senders, and looking at the money and time involved to achieve basically a cooler looking version of the same thing the analogue gauges do, Im extremely disappointed.
