WARMING THE ENGINE…

Piggyback ECU · map switching · safety cuts
A plug-and-play piggyback that reads the factory sensors and clamps the boost signal — with on-the-fly map switching, in-cabin adjustment and configurable safety cuts. The classic first step before a full flash tune, and a useful failsafe after one.
