I needed exactly this. Thank you!

[@igqfresh]

Finally! Awesome automotive technological advances as always, thanks AEM!

[@andrewebb495]

Now I can completely eliminate my stock cluster

If the vehicle has a 3 wire fuel level sensor, do you just use the (-) and signal wires? Or do you need to run a power wire to the third wire still?

[@AEMpowerTVelectronics]

This is a tricky one, we have not seen a 3 wire fuel level sensor, most are 2 wire variable resistance. Wiring and calibration will depend on the actual sensor and its output (0-5v, ohms, frequency, etc)

How can you reduce the refresh rate of the fuel level? I have this setup and working but everytime i turn a corner, accelerate, brake etc the fuel slosh changes the reading. I have tried with input filters but can't find any combo that works. Because race car, the car is never flat or stationary so I can never get an accurate or even usable reading of the fuel level. Any suggestions? Thanks.

I'm running an AEM Infinity 506, as well as the CD-7 display. Would I still need to utilize the CAN module?

[@AEMpowerTVelectronics]

Yes, the 6channel can sensor module (30-2226) is perfect for users with the Infinity ECU because the ecu does not have a native resistance based input for fuel level.

[@mattschmidt9333]

@@AEMpowerTVelectronics That's what I thought. Thanks for the response!

[@TheKeatyBear]

What if your vehicle had 2 fuel level sending units such as a 350z. And can a delay be setup so the reading is not so eradic?

[@AEMpowerTVelectronics]

Yes, and average or rolling average filter can be set on the input to avoid continuous oscillation.

[@marcuspomeroy1035]

How do you adjust the sample rate or an average over time? I don't want the gauge to bounce every time the car bounces..

[@AEMpowerTVelectronics]

Use the dash design software to add a filter to the channel. There is an option in the software right under the input selection for the gauge/value. Something like a 5 second rolling average with a slow update rate would work well. (select value, select input filter, green +, select filter from drop down list)

[@TheProPilot]

Does the resistor go between the two wires basically?

[@AEMpowerTVelectronics]

Yes!

[@keithmitchell4193]

Maybe you guys can do a video on how to set up the RPM inputs
