Difference between two points, where something is switched on and off. Prevents outputs from rapidly change the state of output, close to switching point.
Fuel pump relay activated on output.
FAN output is triggered at 86 degree C, hopefully the FAN gets the job done and cools the engine down, when it reaches 84 degrees C, output is turned off. That's hysteresis.
How many times the signal repeats itself per second. A signals period is the actual time the signal takes to repeat itself.
A signal of 20Hz will repeat 20 times per seconds and therefore have a period time of 0.05 seconds.
Pullup resistors are connected between the input and supply. Allows both high (+5V/+12V and low (0V) transducers to be connected to MaxxECU.
On the above example, by software a pullup resistor can be activated on certain input.
A mechanical switch is connected to digital input, and the other side of switch is ground. Without a pullup resistor a change on the mechanical switch wont make a difference on the MaxxECU digital input.
When a pullup resistor is connected/enabled and switch is open, MaxxECU digital pin is high (+5V or +12V). When the switch is closed, MaxxECU digital input is grounded.
A method to calculate unknown values between two known points in table.
In the above example, we have changed the low and high RPM values, and want MTune to do the calculation between the zero cells.
Select the cell which should be interpolated, in this case select "interpolate horizontal" and click.
Final result after interpolation.
Same can be done in 3D. Select points and press "H" for horisontal, or "V" for vertical interpolation.
Result after interpolation in 3D.
