New FlexFuel Strategy

Now hard coded into the software, there is no need to use Custom Maps to develop your FlexFuel calibration. With the addition of an Ethanol content sensor utilising a 0-5v output, it's now easier than ever for tuners using Ethanol for the first time to create a quality FlexFuel tune without an in depth understanding of RaceROM Custom Maps.
It uses 3D maps to define Ethanol ignition timing, AFR target and boost target with 2D blend maps to determine how they are applied with varying Ethanol content. Overall fuel flow and cranking fuel adjustments are made separately.
This gives you comprehensive control of fuel, ignition and boost for varying Ethanol content levels delivering a true FlexFuel capability from the stock ECU.
