ECU Tuning Box with Bluetooth App Control

The VR Tuned ECU Tuning Box is engineered to enhance the performance of the 2022-2025 Nissan Z 400Z RZ34, providing a significant increase in horsepower and torque. This tuning box directly interfaces with the factory boost and manifold pressure sensors, altering their signals to deliver more boost pressure, which the ECU then uses to adjust fuel and timing automatically. This 'plug and play' design ensures no permanent modifications are made to the vehicle's wiring harness, making it warranty-safe as it can be easily uninstalled before dealer service. This tuning box offers considerable flexibility with 7 distinct performance maps that can be switched on the fly. Control is available through a dedicated Bluetooth app compatible with iOS and Android devices, or manually via buttons located directly on the tuning box unit. Additionally, it includes features such as a programmable warm-up timer, allowing the engine to reach optimal operating temperature before performance settings are engaged, and three custom driving modes (Race, Sport, Eco) that can be configured to the driver's preference for quick selection. The product is made in Germany and has undergone extensive R&D and testing on a Mustang All-Wheel-Drive dynamometer, achieving substantial gains in rear-wheel horsepower and torque. Gains of up to +65 BHP and +85 ft-lbs of torque are claimed over stock figures. It is important to note that this product is intended for racing competition use only and is not legal for use on highway or street vehicles. Purchasing this product requires signing a Vehicle Compliance Waiver. Furthermore, the tuning box cannot eliminate Check Engine Lights (CELs) that are caused by the modification or removal of emissions control devices such as catalytic converters. The product comes with a 5-year limited warranty against manufacturer defects. However, warranty claims require proof of professional installation or attempted installation and all return shipping costs are the customer's responsibility. Neglect, misuse, water damage, or acts of nature are not covered under warranty.
