    Trying to log ethanol content P01 0411

    Im going to try to sum it up as much as possible with what Im trying to achieve by just logging ethanol content.

    I have been running on a stock ECU P01 0411 on speed density 2 bar for my Turbo swap.

    I recently installed a flex sensor and wired into pcm and +/- appropriatly.

    I then licensed and flashed in a stock flex OS 12216125 file. Once flashed to Pcm I can open in the scanner and read my ethenol content and get a value and know its wired corrently.

    My problem is when I use the modifier and make it a 12216125 -> 1252013 OS (2 Bar speed density) with flex still enabled.......At that point I can no longer log my ethanol content, it just comes up blank in scanner. Anyone know the issue? I know its slightly old equipment but I think im just missing something. Any insight helps.

    Thanks!!

    If you log commanded afr, does it still show up as corresponding with the alcohol content? I'm running the same setup on my na setup currently and am in process of building my turbo kit. Even though my fueling error is in lambda, I log commanded afr just to see what it's running on the gas scale. Helps me confirm it's correct. So does the flex fueling modifier work when it doesn't show alcohol content? My commanded afr is 10.89 with 64% alcohol currently. I plan to go 2bar soon, so I hope you get it figured out.
