    2 Bar Histo Issue

    Can anyone tell me why histogram tables 3-8 are not reading out in 2 BAR kPA?

    Thanks

    Mine is doing the exact same thing, I was just getting ready to post it up.. Mine reads the correct KPA in the table display but no where else.

    Yeah, I deleted the stock MAP in the table and enabled the 2 BAR MAP. My boost table 8 in the histogram is reading boost correctly, but none of the MAP referenced tables in the histogram are reading 2 BAR kPA....

    I am sure I am overlooking something simple......

    Tried it, at idle if I give the throttle a little blip the table display will show 70+ kpa and the historgam display never moves off of 30kpa.

    03Sierra, post your log file.

    If your log is set properly, then you have a user defined PID that is causing the error.

    OK, I have narrowed my issue down to the custom pid I created and added to the table view. Everytime I add the [SENS.30.IMP]-14.5 PID to the table, my histogram takes a crap. I assumed this might be caused by the SENS.30 referencing a 1 bar sensor, so I changed the function in the PID to [PID.2333] to reference the 2 BAR MAP. Same results. Everytime I add the custom PID the Histo tables that reference MAP take a dump.

    What are you guys doing different to log boost?

    Do you have it defined as a MAP sensor? If so it's averaging it's value with the MAP Sensor value. Un-define it as a sensor and all will be well.

    It's always the small items, isn't it.....

    Works like a champ by toggling off the MAP Reference....

    Thanks...
