-## Sensor Calibration
+# Sensor Calibration
 
 Before your Speeduino can correctly interpret the signals from the sensors, it must know which sensors you are using. Inputting this information into TunerStudio (TS) writes the correct calibration to your Speeduino. It is necessary to perform this step before you can effectively check your Speeduino build. Note that this is not tuning your system, but only telling it how to understand the signals from the sensors.
 
 This should be completed after completing the Settings for your engine. Your computer must be connected to your Speeduino through TS to perform the calibrations.

 Note that the standard Speeduino build is to have a 2490 ohm bias resistor, which is standard for sensors used by most manufacturers. If your sensor requires another value, you may need to change resistor R3 to the correct value for your sensor. You can try overriding the Bias Resistor Value with 2490 ohms, but check to be sure your sensor reads correctly in TS.

+### Entering Custom Values
 
 Some sensors are not listed in the tables for the common sensors. If yours is not listed, you will need to enter the values into the fields your self. You will need two bits of information: 1. The value of your bias resistor (2490 if you used the standard values in the Bill of Materials, or you have a pre-made Speeduino), and 2. The resistance of your sensor at three different temperatures.

 Note that his procedure can also be used to enter the values of resistance on simulators for testing and troubleshooting. Two points should be remembered if you use simulator values – first, never enter zero for resistance. Although your simulator may go to zero, enter some small value above zero, say 10 ohms. Entering zero leads to false values in the firmware. Second – remember to enter the correct sensor values before installing your Speeduino!

 Before Speeduino can work correctly with your engine, you will also need to Calibrate the Throttle Position Sensor. This must be done using the throttle body and TPS used on the engine. It is best to do this while the throttle body is installed on the engine.
