Ben80 Posted April 18, 2022 Report Share Posted April 18, 2022 Hi, I'm trying to configure my fuel level to my MXG 1.2 dash. I've got 18 litres of fuel in the car yet my dash is reading 52 litres?? I haven't finished measuring the ohms and fuel levels as I wanted to check the accuracy. Anyone know what I've done wrong in the configuration? My vehicle is a 1989 Mazda MX5 with an aftermarket fuel pump. Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 18, 2022 Report Share Posted April 18, 2022 What value pull-up resistor did you use? Did you set the correct pull-up value in the sensor cal? Quote Link to comment Share on other sites More sharing options...
Ben80 Posted April 19, 2022 Author Report Share Posted April 19, 2022 This sounds like the issue as I don't know what you mean? Could you explain what I should have done in setting this up properly? Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 19, 2022 Report Share Posted April 19, 2022 Have a read of these should clear it up: How to wire fuel level sensor: https://www.aim-sportline.com/download/faqs/eng/hardware/sensors/FAQ_Sensors_Fuel_level_100_eng.pdf How to set up Fuel level sensor: https://www.aim-sportline.com/download/faqs/eng/software/rs3/FAQ_RS3_Fuel_level_101_eng.pdf Quote Link to comment Share on other sites More sharing options...
Ben80 Posted April 19, 2022 Author Report Share Posted April 19, 2022 Thanks, I've had a read through both docs. I need to get a resistor but do I need to buy a binder connector? And does this binder connector plug straight into the mxg dash? Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 19, 2022 Report Share Posted April 19, 2022 The binder connector is not needed in your case, you will be connecting directly to the 23pin amp plug. The binder connectors are used on the optional loom that AiM sell for the 23pin plug. Quote Link to comment Share on other sites More sharing options...
Ben80 Posted April 23, 2022 Author Report Share Posted April 23, 2022 So basically instead of the existing fuel level signal wire plugging straight into the back of the 23pin amp plug, i need to insert this pull up resistor and then re-attach to the 23pin amp plug in the same pin location yeah?

Adamw Posted April 23, 2022 Report Share Posted April 23, 2022 Fuel level signal wire goes to any analog input, then you need a resistor connected between the signal wire and 5V (Vref). Quote Link to comment Share on other sites More sharing options...
Ben80 Posted April 24, 2022 Author Report Share Posted April 24, 2022 Ok, I've wired in the resistor and connected it to pin 4 in the 23 pin amp plug. When I go to the Live Measures screen I can't see where the voltage reading is? I've got the old Fuel Level custom sensor that I had setup before. I removed that custom setup but it is still showing on this screen for some reason. Quote Link to comment Share on other sites More sharing options...

Ben80 Posted April 25, 2022 Author Report Share Posted April 25, 2022 No I didn't. I've done that and have now got it reading. Thanks for your help Adam! Quote Link to comment Share on other sites More sharing options...
