What You Can Adjust

  • Fuel Injectors – If you plan on adding bigger fuel injectors, this SCT tuner allows you to adjust for the correct size to keep your tune correct.
  • Mass Air Meter (MAF) – This X4 tuner allows you to select from different aftermarket mass air meters to ensure your tune is specific to your application.
  • RPM Based Spark – With the SCT X4 you are able to add or remove timing by RPM range (0-2000) (2000-4000) (4000-8000).
  • Idle Adjust – Easily enable and select a value for engine idle position. This is helpful for keeping voltage in the vehicle up while running auxiliary electronics off of the vehicle’s power system.
  • Rev Limiter – While this feature is recommended only for racing purposes, it is one of the most important ways to protect your engine from damage. This feature regulated the highest RPM that an engine can reach before the engine is electronically limited.
  • Speed Limiter – Always a popular feature, the speed limiter allows you to change the top speed that the vehicle will reach before the engine automatically limits the power needed to go faster.
  • Traction Control – Allows you to disable the vehicles traction control without using the factory button.
  • Fan Control  Allows you to lower the temperature at which the Fan turns on.
  • Tire Size – Correct the speedometer if you have changed your tire size from stock.
  • Transmission Shift Points – Change the RPMs at which an automatic transmission will change gears.


  • Out of the box SCT devices will not read or tune the FRPP Coyote Control Pack. A custom tune will be needed to handle any modifications (long tubes, CAI, etc.) made to a control pack run coyote swap.
  • This tuner does not work with the Boss 302 track key. You will have to uninstall the track key to be able to use this tuner, even with the regular key.
