I recently installed a Lund E85 Flex Tune on my 350R. For those who may not know the tune allows you to run any combination of 93/E85 mix. The fuel trims and timing curve adjust depending on ratio and re-compensates whenever fuel is added to tank. E85 in my area is just under $2.00 a gallon and the car seems to love it! Curious to know if anyone has experimented with E85 on track days?
