I Now understand why gas gauges are notoriously off. These gas gauges are using resistance or ohms. The float rides up and down a rheostat depending on the placement of the float the system will send a certain amount of voltage as a feedback. Many things can affect resistance this would be highly inaccurate. In industry measurements have to be accurate. We use a system of 4 to 20 milliamps as a feedback with a device called a transducer or load cell. With a resistant base system (ohms) I would suggest making sure all your electrical connections are corrosion free and tight. Re-strip the wires apply silicone dielectric grease reconnect them tightly. If you can pull out the float and spray it down with contact cleaner. Use non-combustible contact cleaner and make sure it's completely dry before you put it back in place. Good luck
This is such a great feature, took me a few minutes from start to finish looking at the existing sender and getting it reading accurate. Just awesome. Great gauges.
I have 2016 Audi A6 V6 Quattro 11000 miles. Fuel range Gauge has incorrect reading. When I fill-up, it shows 490-510 mile which never happen. Dealer says that nothing wrong. I need some advise.
Great information. I recently replaced the gas gauge sending unit/sensor on my car but it still shows only show 7/8 full which is the same as it was before I replaced it. Do I needs to recalibrate the sending unit after the installation so it will read the correct level? Thank you!
@@vegasjack1 Well if you replace old one with identical sending unit logic predicts it should work with out calibration as its same unit. How ever if its not, then you need to do the calibration obviously.
@speedhut On the manual calibration, does the "full" have to be calibrated first?? I ask this because there is no way for me to empty my gas tank. Can I start the calibration with an empty tank on the E setting??
I was thinking of the same thing. While its sure possible to calibrate gauge on the road side when gas runs out its still bit of a pain in the ass, where most people probably empty gas tank by driving short distances at home stead etc or in custom build have empty tank that has been in storage/been just made want to calibrate empty, fill up and calibrate full. Logically it should be possible to do ether way, but only speedhut can say for certain.
When doing a manual calibration on our fuel level gauge you don't need to calibrate full or empty an a specific order. You can do full first or empty first. You can also do them at separate times. Keep in mind that the gauge will not read accurate until both ends are calibrated.

Came looking for a gauge fix, not how to calibrate an aftermarket one.

i got a samdo, im trying to set it where it reads correct, i have 3/4 tank of fuel how do i set this ? someone help me
"How to calibrate a very specific fuel gauge"
How about the test at the end of the calibration.
i know I'm quite off topic but does anyone know a good place to watch new tv shows online?
@Chaim Terrance flixportal xD
Can I reset my guage from dashboard
Where can I buy it?

Yes, you will need to calibrate the gauge to the sending unit.
Thank you for your quick response. Why that important information wasn't posted on the material I got the sending unit from? LOL. Again thank you!
@@tousshong9438 Because it was pretty obvious you would have to re calibrate it when replacing a sending unit.
@@vegasjack1 Well if you replace old one with identical sending unit logic predicts it should work with out calibration as its same unit. How ever if its not, then you need to do the calibration obviously.
@@Hellsong89 So, you don't think just disconnecting the wires to the same guage requires re-calibration? Let alone putting in a new one.
you know there are a couple "t"s in the word buTTon?
Believe me, we tried to convince him to pronounce the TT's! :D
@@SpeedhutYou guys are great😆 Very helpful and informative. Thank you!!
How to know sensor wire in fuel gauge using multimeter?

@@Speedhut In other words, you have to take the fuel sensor out of the tank and make the adjustments on a workbench.
@@discerningmind Not necessarily
I get confused between three wires
But what about the pointnor? What to do now?
