KAM reset huh, maybe I’ll try that next time instead of disconnecting my batteryI've got a flex tune and the way I do it is drive 3 or 4 miles then do a KAM reset. Yes it is kind of a PIA but I have the peace of mind to know the car has learned the current tank's alcohol %
These cars really do need a return fuel system.
I'm thinking mine may be a little low. Its reading about 77. I tested it to about 80-82.5. I did just flash my e85r tune. So excited to see how it goes!Flashed the Flex tune and checked the alch_pct - it's spot on. Not sure why my previous readings were always low compared to bottle tests, even after a KAM reset. I'm just happy it's now displaying a reasonable result.
