Haltech 12 Position Rotary Trim Module (Boost/Fuel/Ign etc)

The Haltech 12 Position Rotary Trim Module delivers precise on-the-fly tuning control through a physical rotary selector. This module integrates directly with Haltech ECUs, allowing operators to adjust critical parameters including boost pressure, fuel delivery, ignition timing and other engine variables across twelve distinct positions. Ideal for workshops and performance tuners requiring immediate adjustment capability during dyno sessions or track development work. The rotary interface provides tactile feedback and reliable position selection, eliminating the need for laptop connections when fine-tuning specific engine parameters across multiple operating conditions or fuel types.
