    Procede V4 Auto Drag Strip Data

    Posting here since it seemed to slip Shiv's mind:

    For the first time ever, I actually drove a 6AT at the dragstrip to test some of the latest v4 beta maps that we've been developing. One of the things we are playing around with is some nifty boost/timing trick at launch. This allows the car to brake torque at WOT, hold 2800rpm, build 11-12psi of boost and NOT overpower the torque converter or rear tires (due to 10 degrees of ignition retard).

    Car (2008 6AT Sedan) has full Stg 3 mods (catless exhaust, catless dps, helix fmic, intakes) plus our meth kit, forge bypass valves and LSD. Run on MS109 fuel. Hoosier slicks on 17" Kosei Racing wheels. Passenger seat was removed.

    One of the things I'd like to encourage everyone to do from now is to post up ALL their runs. Not just the best one. This will show how consistent and stable the car/tune is. Because if you can only get one good run between bad runs plagued by bad boost control, limp modes, weird shifts, etc,., that stinks.

    So here are all the runs from today (in order):

    11.860@121.970 with 1.691s 60'
    11.797@122.193 with 1.686s 60'
    11.922@121.250 with 1.885s 60'
    11.872@121.609 with 1.734s 60'
    11.779@121.999 with 1.606s 60'
    11.942@120.999 with 1.762s 60'
    11.706@121.437 with 1.615s 60'
    11.729@122.055 with 1.654s 60'

    There was no tuning done other than boost target and ignition retard during launch. There was also absolutely no driver finesee during launch All I did was stomp on the brake with my left foot and stomp on the throttle (full WOT) with my right foot. Waiting for 2 seconds and lifted off the brake. From that point on, I tried my best to upshift with the paddle so that shifts occured at 6200rpm. Turns out, looking at looks, i was a little late with most shifts. Especially 1st and 2nd which winds up really quick. I didn't realize that there was so much upshift lag with the 6AT (difference in time between paddle upshift request and actual upshift).

    Here's a datalog of the launch on the 11.706ET with 1.615 60' run:

    I feel the same way about the shift lag with the auto. I drove it for 30 minutes and couldn't stand it.

    Shiv,

    are these unreleased maps, or the latest maps you released (beta)?

    Very nice times. Love how the times are consistent run after run.
