Hi everyone, How i could use this CAN analogue inputs for fuel pressure? ![Press](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/d/da29b06f09825c4aec55fe70d7357bfba8792d56.jpeg) I’m looking to send the data from ADU to EMU, is it possible? Thks ---

CAN analog inputs are virtual inputs, where you can put values from CAN messages. You can configure it in Tools / User defined CAN stream: ![obraz](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/4/4359fb52ec38a9ccbb3b1f9ba2b2a2fc62a5203a.png) ![obraz](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/2/25db4f1ed637b5677781003328ab34f8792d3b1e.png) ![obraz](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/1/14e66f05d97ded7b3269d82811ce1923f8b392a0.png) ---

I still not able to figure out how to do it. I read the manual, but im not understanding how to send. What numbers should I introduce and how to see them on the EMU. Please HELP ---

Thanks for the help guys. Managed to make it work. Still not sure how i did, but it’s working. Need to continue to learn this language. Initially wasn’t enable to read the value, needed to play with multiplayer, divider and offset. Still small diference in value when the pressure switched off and goes low. ---

on emu do exactly as on previous post and on adu as i said…is worn on emu because you have an offset and is wrong on adu because you have wrong multplier. ---

I tried but shows wrong value. Can you please check where is my fault? EMU 4.69bar and ADU 3.2bar. ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/a/af632939dff2d4e43dfecf138ab2e85acba934d7.png) ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/9/921612011d98402843badba7be18125263058871.png) ---

for channel at adu use analogue voltage where is assigned sensor not a pressure and assign that voltage to the sensor at ecu. and calibrate at ecu exapmle analogue 2 is used for a sesnor ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/5/50e898b7f24205513ee888195544fa67e982560c.png)
