A Dyno-Scan kit connects to all 1996 and newer vehicles to obtain diagnostic information and measure vehicle performance. Select one of the product categories below.
It appears that the Auterra product only pulls codes and monitors performance.

If you want to modify your ECM settings you will have to go with something like the Hypertech to read codes and actually reprogram the ECM. My buddy bought one to correct the speedometer after upgrading to bigger tires.
