    Post Stupid Canned Tune for Supercharged LS1 GTO

    Had a chance to work on a supercharged A4 LS1 GTO today.

    Didn't have a wideband so I couldn't make too many changes, take a look at the before and after.

    Here's what I changed so far(coming from a stock "canned" supercharger tune)

    -Removed timing as the intake temps increase
    -Removed timing at the edges of the timing tables
    -High and low octane tables now have a safety margin between them
    -Smoothed out part of the VE table
    -Very small change to the PE table
    -Changed the PE enable to prevent PE from coming on too soon at low rpms
    -Added some torque management back in between shifts
    -Disabled rear O2 sensor codes
    -Speed limiter removed
    -Other minor changes

    Here's what still needs to be done (most of this will have to wait until after the WB is installed)

    -Change the injector data to be correct for Ford green tops (42lb/hr @ 44 psi, vehicle is at ~60)
    -VE table tuned
    -MAF curve tuned
    -PE table corrected for proper VE and MAF data
    -Needs all new transmission table data

    Posting this because someone wanted to see the changes, however I'm always open to feedback.

    I have not done anything with the MAF yet, it is on the to-do list. I recommended full speed density to the customer and we may be going that route in the future. If we did then the MAF would be removed. The blower is of the roots type (positve displacement).
