Yes, automatic cars can be tuned. Automatically-shifted vehicles are not immune to tuning and modifications like their manual counterparts. Just like a manually shifted car, an automatically shifted car has many components that can be adjusted or modified in order to increase its performance - from air intake systems and exhausts to computer chips and spark plugs. The most common type of tuning for an automatic-transmission vehicle is known as reprogramming. This involves adjusting the shift points, shift firmness, line pressure settings, torque converter lockup speed and other parameters to adapt the transmission's operation for better highway cruising or drag racing performance. Other types of modifications include increasing line pressures with higher capacity valves or adding a valve body recalibration kit for improved shift characteristics. Additionally, some tuners even offer custom ECU remapping services that allow users to adjust fuel delivery maps or timing curves via laptop computers connected directly into the engine control module (ECM). With all these options available it’s clear that there is plenty that you can do if you want to tune your automatic vehicle.
