Engine needs to be running for tachometer to be controlled
Hold the rocker all the way up to showcase the Ethanol Content Display.
Tachometer will move to the measured amount of ethanol at the sensor (or to the override value). Each number on Tachometer correlates to 1 percent. For example, 2000 RPM = 20% Ethanol content.
Letting go of the rocker after reading the Ethanol Content, goes back to normal driving displays
