• Ignition Timing Precisely Calibrated for E85 Ethanol Fuel
• NOTE:E85 calibrations are not full flex fuel calibrations, therefore, when using an E85 ECU calibration, the engine is only designed to operate on E85 blends from E60-E85. Using an E85 calibration with pump gasoline or race gas may result in engine damage. Unitronic strongly recommends the use of an Ethanol Content Analyzer, to ensure Ethanol content levels are within the permissible range. When switching between gasoline to ethanol, please useUnitronics fuel conversion guide here. Unitronic recommends usingNGK R7437-9 spark pluggapped to 0.024 +/-0.002 (0.6mm +/0 0.05mm) with Stage 1+ E85 and Stage 2 ECU calibrations, with a replacement interval of 10,000-15,000 miles (16,000-24,000 km).
• Unitronic FLEX fuel enabled ECU Performance Software Calibrations are available for this platform allowing for seamless transitions between 100% gasoline to 85% ethanol and anything in between, without requiring an ECU reflash.This FLEX enabled Software is available for an additional fee and it covers all lower stages up until your highest purchased stage as well.UniFLEX Hardwareis required in order to take advantage of these FLEX enabled calibrations.
