What Parameters Can You Can Adjust On The SCT X4 Tuner?

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 can add or remove timing by RPM range (0-2000) (2000-4000) (4000-8000).
Idle Adjust - Easily enable and select a value for the engine idle position. This helps keep the 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 regulates the highest RPM an engine can reach before the engine is electronically limited.
Speed Limiter - A popular feature, the speed limiter allows you to change the top speed the vehicle will reach before the engine automatically limits the power needed to go faster.
Traction Control - This allows you to disable the vehicle's traction control without using the factory button.
Fan Control - This 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.
Note: Some of these features are not applicable on all models
