Tune pulled from car i bought. Can anyone look over it and help?

[FlipediS]

Ok hears the deal, I bought this car about 2 months ago. and i deiced to pick up an used EFIlive tool. And try and learn it. Well i haven't gotten around to much yet. But i did pull the calibration from the computer and seems to have a tune already. And i just wanted someone to look over it and tell me if its safe. It seems to run great. Though sometimes around 1500 rmp when cursing the motor sounds a little funny. not sure if this is normal, I also noticed when i was flooring it i was only getting 80% throttle. but was an easy fix of the throttle cable. And when i see the spark advance. Was around 30+ when cursing. Is this bad? and once i give it gas. it jumps right up? or is this normal?
What i know about this car? Is at one time the owner before the last is the one that did the work to the car. The last owner didn't have a clue what was installed. It told me it was just a exhaust and a stereo in it. Well it dose have full exhaust. And a higher stall like 3500, then has slp air lid. And looks to be aftermarket fuel pump, Has hot wire kit ran to it. And the owner before the last ran nitrous. not sure how much or anything like that. And the car might have more done to it i dont know. Just as i found out the car has full suspension added on as i was not told about this as well. Oh ya this is a 2001 Ws6 by the way. well any help would be great. and thanks in advance.


Ok so here is the car running at idle.
Then the second video i tried to capture what i was originally talking about. Witch is allot harder to hear in the video. But can hear it. So let me know what you think.

i'm on my Linux OS right now 'studying' so i can't open your file but i can tell teach you how to fish (give a man a fish vs teach a man how to fish)
go to holdencrazy.com
(now it redirects you to tunefiledepot.com)
top of page-click on holden crazy tab
read halfway down page-click on stock tunes
scroll down to pontiac
find 2001 trans am automatic 5.7 liter
that is a stock tune.

save to computer

open up efilive, and open up your orgbackup.tun file
under file click on "open alternative calibration for comparison"
open up the stock .tun file you got off of holdencrazy
once it is opened, click on file again and click on "view comparison summary" or something along those lines...it lets you view the differences between the two tunes


thats a good starting point. you will be able to see what is different from a stock tune to the one you have.

the noise that you hear around 1500...what does it sound like, does it happen while cruising, accel, decel, what gear.

[FlipediS]

Thanks. Ill take a look at the file differences, Its when i'm going a steady speed. If i give it gas or drop it in a lower gear and raise rpm it goes away. I don't know how i could describe it. reminds me if it being half dead like it wants to knock or oing or something. I wish i knew how to explain it better

[Boost]

you shouldn't curse :) Nice car btw! The advice from Crunkmaro is excellent, I would only add that you don't need to be cruising at speed or anything. Just pull the files and do the comparison. Or post it here and we can do it. Good luck

Fliped:

In general it appears your Tune has a lot of changes from stock. I join the rest of the group in saying to do some detective work yourself as far as comparing it vs stock. However your OS is 12212156, which I only see a 2002 to compare to..:confused:.

You can tell it might have ran nitrous as some of the Abuse Management Rpm Limits are set to 7500 Rpms..:sly:. LTFTS are disabled..the MAF and VE have been worked extensively. The Spark Tables are really odd. Very high at cruise and quite low at high load.

Your Log still shows only 80% TPS. It also shows a lot of +STFTS.

Personally I would find out the mechanical condition of your vehicle first. From type of H/C, to the Narrowband sensors.

Your are always welcome to try the CALC.VET method of Tuning:http://forum.efilive.com/showthread.php?15236-A-New-Twist-on-CALC.-VE-Table..Computing-the-Entire-VE-Table. You might want to just load up a stock tune and start all over, or try one of my more conservative tunes here:http://forum.efilive.com/showthread.php?14439-Idle-Tips-amp-Tricks (to compare to only..its an M6 Tune).

Good luck..

Is the noise on acceleration (knock/detonation) (sounds like rapid popping corn)...?

[FlipediS]

Nope the noise is not there at acceleration. just when im going a steady speed sometimes. After work today ill try and take it for another drive to see if i can pick up on how to describe it.

And thanks for looking at the file. Yes it looks as they replaced the computer with one from an 2002 camaro, As for the log. I seen that to. And found adjusting the throttle cable under the hood brought my throttle to 100%

I also picked up the calibrated success dvd to see if that would help me learn any. witch seems most of the information can be used with efilive. Gues in to detail telling how to do most things with efilive as well besides one part. setting up user defined pids? witch i have no clue how to.

But ill try and give the calc tune a try. Im still new to this all. Reason i asked people here. Just wanted to make sure this tune wasn't dangerous on my car.
What is the differences between auto and calc tune? Aslo in a slow process of piecing together a pro charger kit. So my plan is my then to have some clue of what im doing. but will i be using the same method of tuning? Im assuming once i get the pro charger instilled. Will still be some time. That i will use an Custom OS?
Im out in Hawaii. And as far as i been told not to many good tunners on the big island. So figure ill try to do my own stuff if i can pick up on it.

[WeathermanShawn]

I'm not sure what constitutes a 'dangerous' tune..but anytime over 100 parameters have been changed from stock, you just need to make sure every change is warranted. It needs to match the internals of the engine or driving it will not be fun.

The CALC VE method(s) will utilize the MAF and closed-loop. AUTOVE fails the MAF and runs off your 'VE Table'. Both really require a wideband for optimal performance. Adding a Pro-charger will require AUTOVE. Both require a knowledge of your vehicle and ample computer skills.

You just need to dissect every line of your tune..Read up and see whats warranted. IMO, going from stock to your own tailored tune is easier than vice-versa.

Good luck either way.

[Crunkmaro]

I'm by no means anything CLOSE to a tuner, but you already have the responses of a couple 'gurus' (IMO) in this thread so I will gracefully bow out on that aspect, but that noise that comes around 1500 at a steady cruise still irks me. A description of the noise could help in diagnosing...
Does the car shudder?
Does the car hesitate?
Is it a metal on metal sound?
Does it sound like a steady drone that increases/decrease with RPM/speed?
Does it sound like chugging?
Is the trans in "lockup mode" when this noise is occuring?


the part where you said it goes away if speed increases or if throttle increases leads me to believe it may be transmission or driveline related, maybe something related to lockup?

[FlipediS]

Thanks on the feedback. And i current have a wide band. I installed one right away. as for the sound. i think i might of been worried for no reason. "I Hope" actually what it sounds like or reminds me of. Is if i was driving a manual and put it in two high of a gear and tried driving. Witch im assuming that might be what its doing?

[joecar]

FlippediS,

Do you have any close up pics of engine/heads, and of undercar...? We're just curious.

[Crunkmaro]

FlippediS,

Do you have any close up pics of engine/heads, and of undercar...? We're just curious.

+1.

whats the vehicle speed when that happens? does this car have an aftermarket cam?

[FlipediS]

I know the heads are stock because they are stamped 241? But i can probably get pictures latter. After work, It dose have pace setter headers. and cats removed and hooker catback, As for the cam im not sure. Like i said the people i bought it from didn't have much clue about this car. They owned it for about 3 years. and it sat for about two because he was over seas. All they told me was, That It had exhaust and a stereo. and a stall, But once i got it home. I noticed it had kyb adjustable shocks in front. after market springs. BMR subframe connectors, BMR tubular LCA's with LCA relocation brackets, and a TA girdle diff. and it has the zr1 rims with 315s in the back. And then i noticed a hot wire kit ran to the gas tank so im assuming an after market pump, then was thinking it might have a shift kit because the way the tune looked? But not sure. And it had nitrous also because it still has a twisted insanity nitrous controller mounted inside the car. And i did ask them about that and they said that was from the previous owner.

See i live in hawaii. And ran across this car for sell on another island. So i flew other there because it seem to be to good to be true deal. And thats when i thought it was just stock. its and 01 Trans am ws6 with only 33k miles. Witch i bought for only 6k.

But ill try and get some pictures latter today. Im just about to head to work now. 7am here in hawaii.
And once again thanks for everything

[Crunkmaro]

wow what a deal!
when you get a chance and take those pictures...do a quick video of the car at idle. should be an easy giveaway on whether or not its cammed.
i like your car, it keeps getting more and more modded lol.

[joecar]

Yes, shift kit ran across my mind when I saw the trans tables.

If you can get underneath, then remove circular cover from bottom of bell housing and see what color is the converter.

Interesting car, I like it too.

What color are the springs and the shocks...?

[FlipediS]

Just got off of work.. Not able to get under the car right now. Its pouring down rain. And no room in my garage to get under at the moment. So might be tomorrow. And ill will try and get the cover off if i got the time tomorrow as well to see the the color. If its a cretin color what dose that mean? Also will get a video.. Ill do it all at once, As soon as i can pull it out on the the drive way and jack it up. Though here is some pictures of under the car that i took after i first got it Though a bit unless for this but still more the less some pics until i get the ones i need. I have already took off the rear gear cover and cleaned it and resealed since this picture. And no more leaks. It just had the stock 342 in the rear, Would like to swap them out to 372 i think in the future. Also the sound system came with this car to for that price. And one of the reason i think i got it for such a deal. Is because they were military. And where being stationed some where new at the end of the month and had to get rid of it. And they did not have the title in there name. A bank in Texas had it. So they wanted the money up front for it. Then had to wait for the title. But they had all kinds of paper work notarized for me at the base and what not. And felt secure about it. And got the title about a week later. That's the only reason i would guess that someone else didn't end up buying it.

hottt!

[joecar]

The 315's tuck in just right... good stance :cheers:

[Crunkmaro]

damn thats a nice car.

[FlipediS]

Thanks! I love this car. And i actually got a new set of tires to put on this car as well. But going to eat up the rears some more before i put them on haha. Though im a bit excited to see what they will look like on the car. I bought them already, because it seem as now where on this island had these size tires in stock, And the rears shouldn't of passed safety inception. but luckfully i found a place that passed me. again 315's in back and 275 up front , But im going to try real hard today after work to get under the car and get more pics of the motor and everything along with the video.

[FlipediS]

So i finaly had time to get a jack under it today. Though not sure what i should be taking pictures with. As for the TC its blue. And i also got the number of the servo i can see on the transmission and noticed its 77767k Made by Sonnax, so looks to me they did tranny work as well. I still have it on jacks now. And ill get the viedo of it running once i can get it off the jacks.

[Taz]

That's a "super-hold" 4th gear servo - they work very well. A positive initial indicator that whoever did the trans work used quality parts.

Taz

Ok so here is the car running at idle.
Then the second video i tried to capture what i was originally talking about. Witch is allot harder to hear in the video. But can hear it. So let me know what you think.

[FlipediS]

Any feedback?

[Crunkmaro]

sounds normal to me.

correction

sounds normal for an ls1 with a converter. seems like its in lock up, especially when you hit the gas a little bit the rpms seem to raise, noise seems to smooth out, then rpms seem to drop (lockup) and the noise seems to get rougher and choppier.


i hope someone else can chime in on this, but all my stalled ls1s sounded like that.

[FlipediS]

thanks for the feedback..
