Speedometer calibration with an OBDII connection: 

 

*To simplify the setup procedure, ple

ase download out IOS or Android app ‘Dakota Digital Accessory’* 

The speedometer signal from the ECM is normally calibrated to be accurate.   
If there have been changes to the gearing or tire size then the reading can be adjusted from 75% to 
125%. 
If the speedometer reading from the ECM is farther off than this, the ECM should be programmed to 
correct the speed, or the signal feeding the ECM should be corrected. 
 

Input source menu 

The ECD-200BT can read a regular electronic vehicle speed signal (VSS) from a dedicated 

speed sensor or from a VSS output of an engine computer or transmission computer.  It can also 
read OBDII speed in 1996 and newer GM and Ford vehicles, and 2003 and newer Chrysler/Jeep 
vehicles.   

The ECD-200BT will not be able to read CAN speed from aftermarket ECMs like Holley or 

FAST, or non US standard protocols.
