Thanks for the reply and the video! Looks like a good site. I will rebuild the circuit, the original wasn't built by me but it is soldered on a breadboard and as far I can tell all resistor values & capacitor are correct and the correct way around. But I'll build another circuit and see if it's better. If not I'll have to do some more digging. Thanks for the help!

Hi, I copied the circuit in this thread as I have a similar range fuel level sender. However my range seems to be a lot smaller, about 1.4V - 2.7V. Also I seem to be getting 0 damping from the cap circuit. I get immediate and wild changes in voltage that allow the fuel level to change drastically. Obviously especially at lower fuel levels. The level sender is 2 wires with the other being connected to ground. The negative of the capacitor is also connected to ground. I also double checked that it is wired in the right way around. Negative strip connected to ground. Does anyone have any suggestions? The sender unit measured 4-140 ohm's

Hi mate Just tried it out, needed to set it to 16bit & /10 for it to show up but all working now. Thanks so much!

Thanks for the reply. I had tried both those ways, and I got --- at the dash weirdly. Weirdly the only way I actually got figures was 8 bit transmission with no division, multiplication, offset. I will try again today though and try your configuration. Maybe there was something I missed at the time. Thanks.

Hey guys, I have a G4+ Storm connected to Link MXS Strada 1.2. I wanted to get the fuel gauge working so after a bit of searching I found some threads on the custom CAN streams and downloaded them. I thought I had it figured out as I got it to display values (sometimes) but the values don't always match the values in the ECU. I am using AN V 3 for the fuel level sensor. So the weird thing that it does is as follows, ANV3 scaled (0.5-4v ish) so it shows tank 80% full then the dash will show 80% ANV3 scaled (0.5-3V ish) so it shows a value of 67% the dash suddenly shows 7% ANV3 scaled (0.5-2v) so it shows a value of 55% the dash then shows 105% I'm somewhat perplexed how scaling the analog input is effecting how different the value in the dash is compared to the value in the ECU. Shouldn't the ECU just send the value? if the offset or factor was fixed that could be worked with but it doesn't seem to be. Also it doesn't seem to transmit if it is set to 16bit, only when set to 8bit. I have updated everything to the latest firmware to see if that fixed it. alas it did not. I've tried setting things up fresh probably 4 times now, tried offsets and anything else I can think of. I'm sure it's something i'm doing wrong, first time working with CAN so directly but i'm out of ideas. Help would be greatly appreciated!
