- Summary
- This Preliminary information communicates concerns created by an aftermarket ECM calibration installed by fleet companies. The Fleet companies install aftermarket ECM calibrations to limit the vehicle speed to approximately 70 mph and reduce the over all power output. This calibration also reduces the engine idle speed and may induce a vibration at idle. If the vehicle needs to be returned to factory specifications, the ECM must be replaced and programmed.
Owners of these vehicles have filed 282 complaints in the engine category.
