    Hey guys,
    I ask that you disregard the previous logs.
    The car was not set in the menu 4/2 (BEF).
    Also, I updated the Beta 32/16 firmware.
    What do you think of these new logs?
    23.6 psi on map 5 seems like too much. Pull hard, but trims on the limit and afr lean.
    Any help is much appreciated. Thanks.​

      Your HPFP is struggling, trims are high and maxing out at times but AFR's look normal so far.

      Not sure what WMI mix you are running butt more methanol will lower trims. or the flash can be adjusted by increasing the scalars to lower trims.

        I'm already running 100% methanol.

        I will try to change the WMI configuration, add more nozzles or port.​​

          You can also adjust the scalars in the flash to lower trims. Have you tried running the BMS flash, it's free.

              Great...you can open that flash and adjust the scalars in it. I'd start with increasing them .1
