Certain vehicle manufacturers have started implementing locking mechanisms in their Vehicle Control Modules (VCMs) to prevent third-party tuning. While the VCM Suite can typically read these vehicles without issues, writing an updated tune to them might necessitate special hardware. HP Tuners offers solutions for these scenarios. For many vehicles, we can upgrade the existing VCM to enable tuning with our software or exchange it for a pre-upgraded controller. In some cases, a special cable may also be necessary to facilitate the tuning process.
