    335is Sport On/Off Timing and Boost

    Sport mode is suppose to only make shifting faster, however there is more behind this unless I just got the short end of the stick.

    When Sport is On timing is lowered and boost, but when Sport is Off timing is significantly increased and boost is increased also.

    Shouldnt this be the other way around ?

    Does your RENNtech tune only modify the Sport Mode Off (default) settings??

    Would be interesting to see if any 335is' with COBB are logging similar data

    I don't really know I never entertained the thought as it was consensus that the Sport feature only affected the DCT shifting and not timing and boost. I never drive with Sport Off, it was on accident when doing logs I forgot to turn Sport On.

    Yes, post the logs to confirm. It should be the other way around.

    Kinda funny that you found out by complete accident that you've not been running at full power Click here to enlarge

    Logs attached, sorry they are not graphed, just the raw data from the BT tool converted

    Sport OFF.pdf

    Sport On.pdf

    I did 3 WOT runs prior to logging with Sport Off, pulled over for 5 minuted then started the other log with Sport On. Thats why my IATs look high on the last run

    I think what was going on is a combination of timing corrections and CAT corrections are making it appear that there is a difference between Sport and non-sport.

    To test this theory you should grab several datalogs with sport on and off.

    I think it's entirely plausible there are different sets of tables for the various modes. FWIW, the 6AT DS mode has a different throttle mapping compared to D. I was actually considering making D stock throttle and DS linear for easier modulation.

    Looks like your right. I did 3 runs with Sport On and 3 runs with Sport Off today. Timing and boost pretty much shows no big difference as before.

    That's what i was thinking. In the runs you posted originally the CATs were high enough in the "sport" log to get into the CAT correction factor tables where the "non-sport" log was not. High charge air temps can KILL timing Click here to enlarge
