    Like all of your tuned cars... Stock like numbers.

    Why is that so hard to do? Why do you constantly "dodge" this very simple question?

    Am I the only one who notices that you NEVER answer any questions... You just ask new and confusing ones...

    OK... Hands up, who cares if my car no longer shuts off cylinders, but now it is slower to 60', slower to the 8th, and slower in the quarter.... When you lose against a car running the stock tune you can say "Ya but your car shuts off four cylinders at 1600 RPM"

    If it makes the car slower, no one cares.

    My point is you DON'T Know what you are talking about!!!!!!!!!!!!!!!!!!!!!
    1. We have done several back to back runs!!!! You don't like them
    2. It is very important to Know exactly how much Code's car put down on the Dyno with the stock PCM!!!!
    3. All Northstar's have Cylinder Deactivation from the Factory!!!!
    You act like my tunes kill 4 cylinders, but the stock ones don't. They all do, but you for some odd reason don't understand that!!!!!!!!!

    I am tuning the cylinder deactivation way up now. That has been one of my goals. Remember?

    You keep focusing on a broken car why?????????

    You have NEVER done a back to back "change ONLY the PCM" run. at a track or at a dyno

    NEVER...

    The reason we focus on Codewise's car is 'cause it is the ONLY one that actually HAS done a back to back run at a dyno or at a track. PERIOD.

    You keep saying they exist... and you have for almost 2 years now... but they don't, they were done on the street, with questionable data loggers or they show stock like numbers on the dyno.

    You know its funny, Highline comes back to the forum after a few months absence... He says he is going to run his car at the track soon... Cool!

    All I suggest is that he does a back to back test one run on the Stock PCM and one run on your Tuned PCM and YOU get all defensive...

    Why does this simple and yet scientific test concern you so much?
    Why don't you want to prove your tune the best way posible?
    Why do you seem actually determined to not have a test like this happen?
    What do you know?

    I don't have a car to do the back to back test that meets your standards.

    That is EXACTLY what I was saying all along. Let's cut out the graphs, the tables, the pictures of modified N*'s and the talk (tech talk that is). Lets see some real world, back to back runs stock vs "tuned". It's the only way.

    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
    This is Highhline's time with NO stall converter!!!!!!!!!!!!!!!!!!!!!! back in 2007
    That would make this about as stock as Codewize's car correct?????????
    Just my tune and the corsa exh was the only difference correct?
    1/8th mile 9.842 @74.08
    1/4th mile 15.143 @ 92.84 mph

    Now what is wrong with the picture?

    If you don't remember the 2nd pass was on the stock PCM.

    Re: What is an Aj tune?

    Last time my calculator looked at it:

    First run
    Using the ET method, I come up with 208 horsepower
    Using the Speed method, I come up with 229 horsepower

    Second run
    Using the ET method, I come up with 228 horsepower
    Using the Speed method, I come up with 250 horsepower

    The ACTUAL numbers are meaningless, the DELTA of the numbers show the real deal. The car was faster and quicker down the quarter mile. I used a default figure of 4000 lbs. If I used a higher number, it would be higher hp numbers, lower, lower hp numbers. The weight is a constant in this calculation.

    Re: What is an Aj tune?

    The torque defeat device came into play about January of 08. Hmmmmm
    I think that added to Code's run. Hmmmmm
    That again proves Code's car didn't like my tune and his car ran slower than Highline's car and he had the button

    I am not sure what that means. hmmmmmmmmmmm Why don't you tell us?

    Using the ET method, I come up with 232 horsepower
    Using the Speed method, I come up with 256 horsepower

    Using the ET method, I come up with 254 horsepower
    Using the Speed method, I come up with 279 horsepower

    Re: What is an Aj tune?

    Is that both runs for Code's car or one from Highline's and one from Code's?

    Code ran a 1/4 mile 15.49 @ 90.28 MPH on the stock PCM
    Code ran a 1/4 mile 15.61 @ 90.17 MPH on my PCM. This is OK for me. This is not what I am debating
    Highline ran a 1/4th mile 15.143 @ 92.84 mph & 15.169 @ 93.21 mph on my tune. This is my point!!!!!!!!!!!!

    How ever you look at it a car with out any DTC's setting ran quicker and faster than a that a car setting DTC's and a STOCK TUNE. Is that is a fact Correct?
