    Going to the track

    OK so this is somewhat of a first stage tune test. I'm heading to the track tonight. I'll post results later.

    In the interest of not killing the car I'm only going to make 2 passes. One with the AJ tune and one with the stock PCM. I've raced before so I'm familiar with the situation.

    If somethings a little askew or I feel like I didn't get a fair launch I'll make another pass.

    Keep us posted, AJ finally put my PCM in the mail.

    I would have to wait till neat the end of the year to hit the track, it's raining here in Tampa every day!

    Re: Going to the track

    OK the result are in, after a long wait due to some import driver blowing up and spewing oil all over the track.

    Vehicle Stats:
    Volant intake, 1/2 tank of fuel (8 gals)?
    80.6 deg F, 81% humidity


    Pass # 1
    AJ tune with TQ defeat system
    reaction time .300 <<Not so hot but I haven't raced in 20 years
    1/8 mile 10.2 seconds @ 72.57 MPH
    1/4 mile 15.61 @ 90.17 MPH

    Pass # 2
    reaction time .094 <<Much better
    1/8 mile 10.1 seconds @ 73.35 MPH
    1/4 mile 15.49 @ 90.28 MPH

    Pass # 3 after the long wait. I probably shouldn't even post this because it was a terrible red light run but here it is
    reaction time -.068 <<There's a long story here
    1/8 mile 10.53 seconds @ 72.81 MPH
    1/4 mile 15.94 @ 90.02 MPH

    Re: Going to the track

    Nice.

    If you take care of these (routine maintenance), and spend a little $, you can pound them all day at the track... and on the way home... and on the way to work the next morning... on the way to lunch... on the way home, again.

    Re: Going to the track

    LOL, so now the interesting thing here is if you do the math and subtract out the reaction times, you'll find that both good runs are exactly 15.39

    So, AJ where do we go from here? Can I have my 01 tune back?

    Re: Going to the track

    The reaction time shouldn't mean anything. Unless you were bracket racing. Otherwise on a "test and tune" night the reaction times aren't figured into the 1/4 mile times. Basically, timing doesn't begin until you move. Hate to bum you out like that, but on your 15.6 you ran a 15.6 and on your 15.49 you ran a 15.49 same for the 15.9.

    I am a little confused also, are all 3 runs on AJ's? Just the 1st? First 2?

    I am happy you got down to the track, wish you'd have gotten some more runs, but there are good days down there and not so good ones. It's nice the few times you get down there and it turns out to be a perfect day, track, amount of people, and weather. Rare, but nice.

    Re: Going to the track

    Runs 1 and 3 are on the AJ tune. Run 2 was on the factory tune.

    Are we sure about the reaction time thing?

    You should have called me a day before and I would have talked you into removing the head lamp. It is pretty easy and well worth it

    Lets just say the 15.49 had the least amont of tire spin and it has a stock tune correct.
    Hmmmmmm
    14.6 looks pretty good out of a slightly heavier car with the same gears, a slightly taller tire and same intake

    Re: Going to the track

    Agreed! I'll do some track runs after installing the PCM and see where I end up.

    AJ, removing the front headlamp shouldn't be necessary to see an improvement. You can't run like that on the street.
