sargii Posted August 19, 2020 Report Share Posted August 19, 2020 Hello. I have an evo 7 with the Vipec V44 plug-in updated to the latest firmware. and i would like to run a flex fuel tune. I see that there are dual maps, the ability to run a flex fuel sensor. I have seen somewhere that in the latest firmware that you can run a flex fuel set up but I have also seen that you can only use 98 or e85 and need to switch maps depending on the fuel you wanted to use, if I was to run a flex fuel sensor will the V44 be able to run a proper flex fuel set up and adjust the tune to suit the ethanol%? I have spoken to a tuner who said its possible and another that has stated that i will need to order a new ecu in order to flex fuel. I thought I will ask here as i don't want to buy a new ecu if i don't need to. thank you all for the help. Quote Link to comment Share on other sites More sharing options...
