EMS Accessories for Engine Management Setups

EMS accessories are the small parts that make an engine management system easier to use and adjust. Tuners fit them to add inputs or controls so a driver can change certain settings without plugging in a laptop. A trim pot, for example, gives you a physical knob wired into the system. Depending on how the tune is configured, it lets you select between preset adjustments such as fuel or boost trims.

We currently have 1 product in stock in this category, from AEM: the AEM 12 Position Universal Trim Pot. It is a universal part, so it is meant to be wired into a suitable setup rather than made for one specific model.

  • Confirm your engine management system has a spare input that supports this kind of control.
  • Decide what you want the knob to adjust and plan the tune around it.
  • Choose a mounting spot that is easy to reach and away from heat and moisture.
  • If you are unsure about the wiring, talk it through with your tuner first.

To check what works with your build, pick your vehicle to see what fits.
