Hi guys! Recently, I´ve bought a bluetooth adapter for my Ecumaster classic, and I´m using Realdash to show some data in my phone. More or less, I already found everything I need but, there is no way I can find Volumetric Efficiency.I tried with some fuel related inputs, but none of them seems to work. Do you guys know where I can find that input in the input list? Thank you in advance. Kind regards ---

RealDash has inputs VE1 and VE2, but I’m not sure if Ecumaster is sending those over the Bluetooth connection. Can you ask Ecumaster for support on that? ---

True, I´ve seen both VE1 and VE2. In my case I´m working with VE1, but I´ve tried with both and none of them shows anything. I´m gonna ask Ecumaster to see if they can help us with this. Thank you!
