Nissan R35 GTR Flex Fuel Kit – Analog Only
Introducing the Visconti Tuning Nissan R35 GTR Flex Fuel Kit, the most advanced and user-friendly flex fuel solution available. This kit is designed to work with older versions of EcuTek RaceROM and Accessport systems that hijack analog sensor inputs to communicate with the factory ECU.
Our Ethanol Content Analyzer outputs a 0–5V signal and can be configured for either 0.5–4.5V or 0–5V operation. Configuration, advanced diagnostics, and over-the-air updates can be performed using both iOS and Android applications.
What’s included with the kit:
- Visconti Ethanol Content Analyzer
- Genuine GM Continental Ethanol Content Sensor
- Visconti Flex Fuel Sensor Bracket
- Visconti Fuel Rail Fitting
- Visconti Plug & Play Wiring Harness
- Visconti PTFE Fuel Lines
Technical details and development history:
Developed and refined over more than 15 years on the Nissan GTR platform, our kit reflects continuous engineering improvements driven by real world use. We were the first to develop a flex fuel kit that communicated directly with the factory ECU on a vehicle that did not originally include that functionality, originally developed on the Nissan GTR.
The ethanol content sensor is mounted on the left side of the engine bay firewall using a black anodized billet aluminum bracket designed for durability and a clean factory appearance. Fuel line integration for the sensor is handled through a black anodized billet aluminum adapter that connects directly to the OEM fuel rails and our PTFE fuel lines.
Reliability has been improved over earlier designs. The updated fuel rail fitting incorporates a secondary external O ring to account for variation in the inner diameter of factory GTR fuel rails, reducing the risk of seepage or leaks over time. The supplied PTFE fuel lines use EFI style quick connect fittings and feature a hydraulically crimped collar assembled using an Aeroquip ProCrimp 1380 to ensure consistent and repeatable assembly quality.
We take pride in knowing the name of every individual involved in producing this kit, which is proudly designed and manufactured in the USA. The harnesses are handmade with automotive-grade TXL XLPE insulated wire and assembled in an ISO Certified Facility.
