Is excited to present to the Stinger forums: The Kia Stinger RaceChip XLR Throttle Response Controller (BUY NOW) Description: The newly developed RaceChip XLR is designed to increase responsiveness on the road. Their innovative throttle tuning system lets you tune your engine’s reactions to your taste – choose from 7 separate tuning stages. You’ll love your car’s improved dynamics. The RaceChip XLR is installed between the throttle pedal sensor and the engine control unit. Depending on the XLR’s tuning stage, it either amplifies or reduces the signals sent by the throttle pedal sensor in accordance with characteristics defined by our engineers. The effect is that you can choose how your car reacts to your throttle inputs. There are two ways to adjust throttle using the RaceChip XLR! The first can be controlled conventionally using a newly designed Controller which is connected by wire to the Brainbox. The driver can use the Controller to select any of the tuning stages at any time. The second can be controlled using the RaceChip App giving you the option of controlling XLR right from your smartphone. RaceChip XLR communicates with your phone via Bluetooth.
