    DFCO or no DFCO

    To tune with or without DFCO?
    Advantages or disadvantages of tuning with and without it.

    I dont really care for gas mileage.

    Thank you

    From what I've read it's with out DFCO as it skews any data you have recorded that you are using to manipulate the tune. After tuning switch back on

    or just filter it out in the histograms based on fuel trim cell, or throttle position and negative change in speed or rpm, or something else. FTC is the quickest in my opinion.

    Im pretty sure im already using a filter for it based onFTC.
    I took an 8 month break from tuning and im trying to catch back up. Seems i just forgot some of the basics lol
