I have been using a E85 test kit to see ethanol content before mixing and it seems that it is usually around 70% , so I mix about 3.5 gallons of it in with my 93 octane .
absolutely, my car keeps throwing a “mixture too lean” code on a e30 blend and Burger tuners say “don’t worry about it”. I tried explaining to them that it stumbles sometimes on WOT (not every time ) , anyways we need the ECU to be unlocked .
I am also getting a mixture too lean code . Running JB4 with Titan Motorsports catless downpipe and e30 blend fuel on map 5 . Check my intake and wiring , everything’s looks good . Any possible help would be appreciated.
