Flex Fuel Kit V2

The Visconti Tuning GT-R Flex Fuel Kit (V2) is a 'plug & play' system designed to eliminate the need for manual fuel testing at the gas station. This kit, when used with EcuTek RaceRom software and Visconti Tuning custom maps, provides calibrations that adapt to varying ethanol content in your fuel. It allows for dynamic adjustments to key engine parameters, including cold start cranking compensation, maximum target boost, ignition timing, air/fuel ratio, cam timing, and even the fuel economy gauge reading. The V2 kit features several updates over its predecessor. It includes a new CNC billet fuel line adapter that retains the stock return line and a redesigned CNC billet ethanol content sensor bracket for clean firewall mounting. The stainless PTFE fuel lines are now coated in black for a more OEM appearance, and the overall fuel line placement has been redesigned for easier installation. The kit integrates a Zeitronix Ethanol Content Analyzer with a slim GM Ethanol Content Sensor, connected by two black stainless PTFE fuel lines. The adapter attaches to the rear of the fuel rail, and the system plugs directly into the secondary air pump plug, typically located near the battery.
