Why You Need This

Every serious tuner knows the frustration of fixed ECU maps that can't adapt to changing conditions. Whether you're running different octane fuels between events, adjusting boost for varying track temperatures, or fine-tuning ignition advance for maximum power without knock, the 12 Position Rotary Trim Module transforms your Haltech ECU into a truly adaptive system. In turbo LS swaps, this becomes invaluable for boost control - position 1 might run conservative 0.5 bar for road driving, whilst position 12 delivers full race boost for competition work.

We've fitted these to countless builds where drivers need instant parameter adjustment without laptop access. Think time attack cars switching between qualifying and race maps, drag racers adjusting launch control settings between rounds, or rally cars adapting fuel delivery for varying altitudes. Without proper trim control, you're either running conservative maps that leave power on the table, or aggressive maps that risk engine damage when conditions change. The rotary design provides positive, tactile feedback - crucial when making adjustments mid-corner or during high-stress driving situations.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range including Elite 550, 750, 1000, 1500, 2000, and 2500 models, plus Nexus R3 and R5 systems. The trim module integrates seamlessly with Haltech's auxiliary output control, allowing assignment to virtually any ECU parameter through the tuning software.
