Is there a big difference at the track or just in performance between the 2dr GPs and the 4dr like what I have? Also, with my mods what should I expect at the track, because I ran twice and my numbers were not near what 1997grandprixgtpsaginawmi posted.
Here is my times: http://i106.photobucket.com/albums/m252/escapest01/untitled.jpg
Also I received the OBD2 today. Messing around with that. I wanted basically to figure KR which I believe I got 0.0. I wanted to know what is the easiest way to use this scan tool and how to just do a quick run with it.
By the way, I had a 120lb passenger on board, first time at the track, and the tires spun like mad.
Do you all prefer manual shifting or just auto at the track?

Coupe and Sedan are only about 100lbs different. I've seen Coupes of the same year get taken by Sedans, and Vice Versa... It really depends on the car, and the driver.

Your launch needs improving... Get your 60' times down to 2.1 and your ET's should improve by 2 tenths.... Maybe more without a passenger..

If you have a factory PCM you will benefit by shifting manually. Put it in 2 to start and manually shift to 3 at 93MPH. Since your trap speeds are around that, you will be shifting right in the traps. Just don't hit the rev limiter.
If you have a reprogrammed PCM, just put it in 3 and go.

What scan tool did you get????

I just ran mine in drive lol, and I got 14.75 or whatever it was. Your saying by running stock and putting it in 3 I should do a little bit better even ???

No, If you've got a stock PCM and you put it in 3 your car will shift to 3 at well under the 5800 RPM rev limiter...
Since I never look at the tach, I can't tell you the RPM's, I'm going to use MPH as an example.
I believe if you go WOT in 3 or D your car will shift into 3rd at around 85MPH. If you manually shift, you can hold 2nd gear until around 93MPH(Rev limiter hits at 95MPH).
This will give you some gains in your ET, and pending on how you work it, your MPH.
When you start trapping at faster than 93MPH it begins a whole new train of thought at the big end.

I bought the Alex Pepper device.

I have the Alex Peper Scanner.

I've found the easiest way to do it, is to set it up before your drive.

Bring up the enhanced parameters and select supported and and send. When all the supported parameters are shown select the parameters you want to view... For instance I select
KR, Mis1 through Mis6 and TG. Then I save it in my favorites.
Next time you start your scanner select favorites/open and find whatever you named it. It will only show what you want to see.
Peper has designed it to show misfires(among other things) with a drop down menu, but it still doesn't show KR, so if the dropdown menus don't show you wnat you want to see, you can set up your favorites to show you what you're looking for.
The scanner is constantly recording, so when you get done making a run, you can stop scanning, give the file a name and go back to it later to view the results.

Thank muchly. I was reading how to get enhanced graph to an excel file but my numbers were not showing up in excel just the abbreviations. I will try this setup you just outlined.

you need good tires/ nitto drag, mickey thompson et streets, or bfg drag radials

Consumer Guide 2 vs. 4 doors:

Consumer Guide

20gtp02, were those times when you were stock, because you should be running much faster than that. Also... your 60' times need work. You should feather the throttle to reduce wheelspin, because even if you have a low 14 - high 13 second car, you're gonna run 15's all day long if you gun it from a stop.

Your R/T's do not count towards your ET, it's just that they can determine who the winner is if you're bracket racing. Of course anyhow, it certainly wouldn't hurt to get those down.

R/T doesnt effect final time at all.

Your car should be faster than that.

i looked at that report and thats what i thought, a 4 door is the same just with a piller and an extra door and not much of a weight difference

Well, the coupes are better. I like telling people that Jackie has the largest production doors. I think it's true?

I just posted that because I found that and I made this thread and wanted to add it for future reference. Yah, those runs were no prep, gf in car, first time running, I think I had a 3.4 and tstat, plugs, wires, and ubend resonator. I spun like crazy and didn't know shit. I am going to try and run this wednesday, I expect in the 13's for sure! My buddy is going to come along and he has a Powertuner, so we should be golden!

Does anyone know the what mph the rev limiter kicks in in first and third for a stock PCM?
