MANUFACTURER LOCKED CONTROL MODULES

Some vehicle manufacturers now put locking devices in their VCMs to prevent third parties from tuning the vehicle. Although most of these vehicles can be read by the VCM Suite without any problem, writing an updated tune to these vehicles may require special hardware.

For many of these vehicles, HP Tuners can upgrade the existing VCM to allow it to be tuned by our software or exchange it for a controller that has already been upgraded. For other vehicles, a special cable may be required.
