With V3.3.4 we have added Flex Fuel support to the FK8. This uses a ethanol content analyzer connected to the ECT2 input to modify fuel, ignition & boost to run at any level of fuel ethanol content without reflashing.
This is a big deal for the FK8 because this single modification (Flex Fuel support) running 40% ethanol will add more power than an intake, downpipe, exhaust and intercooler combined. Before you ask... if you run Flex Fuel and then an intake, downpipe, exhaust and intercooler you only get marginal gains (~10hp) over just Flex Fuel. Diminishing marginal utility of modifications.
Since the FK8 fuel pump flows so little what we have done is add a air charge by ethanol table which limits air charge so that the fuel pump will be within its limits no matter what ethanol content you run. 0 to 85% works. Peak power is right at 40% ethanol.
Make sure you have our Traction Control enabled.
