Blitz Speed Jumper

The BLITZ Speed ​​Jumper cuts the speed limiter that limits Japanese domestic cars to 180km/h (140km/h for domestic light cars). This makes it possible to fully utilize the vehicle's inherent performance. The Lexus RC F/GS F version controls shifting based on signals such as throttle opening and speed, achieving smooth gear changes even at speeds of over 180km/h. It has a compact design that fits inside the vehicle's ECU box. For the Lexus LC500, the control utilizes the factory circuit mode, so the shift change and combination meter operate in the same way as the factory ones.

Since it only controls signals related to the speed limiter, speeds of over 180 km/h can be displayed on the vehicle's combination meter or OBD monitor such as Touch-BRAIN (with some exceptions). It uses a dedicated harness for each vehicle model and has a completely connector-on design.
