    There's a config parameter to prevent the ECU from trying to open the TETV as well. Let me dig it out for you. Otherwise RF calcs could be a bit funky if it's accounting for tank ventilation that isn't actually occurring.

        TETV valve can be prevented from opening by setting K_TE_TVTE_GA to 0 (default value is 0x80 (1.0 with conversion applied)). I have confirmed this behavior via logging. I'm not sure what version of MSS54 software you're running so can't give you the exact address of the parameter.

        IMPORTANT: For anyone else reading this. DO NOT leave your tank ventilation system disabled without having an alternative mechanism in place like OP does.

          I deleted the sensor. I'm thinking I should have kept it. Too late now.

            Good to hear, I kept it, I plan on plumbing the sensor into this bung on my section 1..​ the other bung is for back pressure.
