The firmware of the Toyota Highlander 3.5 (2018) was performed with simultaneous correction of the electronic throttle pedal. The automatic transmission shifts became precise and smooth, and the fuel system was adjusted. The chip tuning was performed on-site, which provided maximum convenience and minimized the time required for the procedure. Thanks to the professionalism and use of modern equipment, the total duration of the procedure was approximately 1.5 hours.
As a result, the engine's power has been increased from 249 to 295 horsepower, which has positively impacted the vehicle's dynamic performance. The engine's elasticity has significantly improved, resulting in an instant response to the accelerator and a faster and smoother acceleration across the entire RPM range.
The increase in torque from 356 to 367 Nm has enhanced the vehicle's traction, particularly noticeable during overtaking maneuvers and under heavy loads. At the same time, the engine's reliability and resource are preserved, and the average fuel economy reaches 12%. Chip tuning makes the Toyota Highlander more efficient and comfortable in everyday use, without compromising the vehicle's safety or durability.
