    2011 Coyote Mustang - Headers, etc

    Hi,

    Please help, investigating what it takes to convert our project car track only, and going catless. Looking through the tune repository and posts here to find out what needs to be adjusted for a Coyote with BBK headers and no cats.

    I get the transport delay so no help needed there.

    For catless tho, I'm confused. Looking through "catless" tunes in the repository, I am not seeing any real changes from stock looking at my existing calibration. When I run a compare not noticing any of the MIL's disabled, or catalyst test and MIL disabled like I thought I might see in these "catless" tunes in the repository?

    Can anybody point me to a list of which settings to disable when going catless? Or is it possible this car already had those parameters adjusted for catless and later they put the cats back before we bought it?

    Here's the current calibration...

    2011 Coyote Mustang Auto E-Force rev 2.3 stock manifolds and OE cats.hpt

    Edit, here's my attempt at what I think I should change... am I close, anything wrong? missing?

    2011 Coyote Mustang Auto E-Force rev 2.4 no cats + headers.hpt

    Thanks!

    You'll need to disable all MIL lights dealing with catalyst efficiency and b1s2 b2s2 ONLY OFF ROAD USE
