How JIYUTEC Compares
Safeguard. Never Damages Your Car.
At JIYUTEC, safety is always the top priority. The J25 is engineered to fine-tune throttle sensitivity without interfering with your vehicle’s ECU or wiring. It works as a signal controller only, meaning it optimizes response and performance while leaving all safety features intact. If you ever disconnect the unit, your vehicle instantly returns to its default factory settings.
For added peace of mind, the J25 comes with a built-in failsafe system. In the rare case of a signal fault or abnormality, the controller automatically switches back to the original accelerator signal, ensuring full control and safe driving at all times.
And because we stand behind our product, every J25 includes a 30-day money-back guarantee and a 3-year warranty.
