Lol yes! Home brew oft! Haha uber curious how fast that device flashes! And after working with ecutek the custom map shit is awesome can't wait to get that nailed on your car. Lyn is thinking about buying an frs this week :x the ill have another test car and can throw my flex fuel sensor in her car to finish tweaking every part of that adjustment map on yours.
I ended up testing out giving Brent a flex fuel map with the map switch to select ethanol content basically. Then if he were to ever switch in a sensor it would flip over to regular flex fuel. Since he isn't allowed e85 or a flex sensor in his race class it was kind of an "in the middle" approach. And now the map wil directly copy / paste to my car

. I'm jelly his actually has been starting... Looks like when my car was tuned it never had a cold crank map created based off ethanol sensor. Fail. -.-
