B58 S58 X58 FLEX FUEL

$ 490.00

The Visconti Tuning X58 Flex Fuel Kit is the most advanced and user-friendly flex fuel solution available. This fully CAN bus-integrated system communicates directly with the factory ECU while keeping all OEM sensors and fuel lines intact.

With true flex fuel support, the tune automatically adapts in real time to the ethanol content in your fuel tank. There is no need to switch maps, drain fuel, or plan fill-ups around specific blends. Whether you’re running pump gas, full ethanol, or anything in between, the vehicle adjusts seamlessly to deliver optimal performance and safety.

CANBOX is our Bluetooth (BLE) Ethanol Content Analyzer that provides core flex fuel functionality. It supports both iOS and Android applications for configuration, over-the-air updates, and advanced diagnostics.

CANBOXPRO adds four configurable I/O channels. These support 0–5 volt sensor inputs for features such as fuel pressure or coolant pressure monitoring, as well as PWM outputs for triggering relays or controlling auxiliary systems such as nitrous or meth. CANBOXPRO allows additional inputs to be added now or expanded later as your setup evolves.

 

What’s included with the kit:

  • Visconti Ethanol Content Analyzer
  • Genuine GM Continental Ethanol Content Sensor
  • Visconti Custom 180 degree quick connect fuel fittings
  • Visconti Plug & Play Wiring Harness

 

PT-CAN v2 Harness: (Manual Transmission Cars)

Our original plug and play wiring harness is compatible with all tuning platforms. It is the only harness compatible with bootmod3 or manual transmission cars.

PT-CAN2 Harness:

Our new plug and play harness is compatible with both EcuTek and MHD+. It is designed to keep all wiring inside the engine bay for an easy installation.

PT-CAN2 Race Harness:

The Race version of the PT-CAN2 harness is designed for cars with upgraded turbos which have the CCV Heater removed.

 

Technical details and development history:

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.

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.
