returning to stock problem...

[1SickGT]

recently i took my turbo GA back to stock. unfortunately, i dont have the stock ga program to flash it with. mechanically my cars all back together, but it runs like a$$ because it has a turbo tune. is there anyway i can get the stock file and simply flash mine with and have it run ok? if so, does anyone out there have a stock calibration file they can send me, and will it be compatible to my HPtuners software? thanx for the help. any input is appreciated.

Your local dealership can do it for you I think.

Donny,

Remember, you don't want to go completely back to stock unless you put the AIR injection back in... You will still need "some" of the changes...

[1SickGT]

todd,

im not sure what changes i should keep.
i had thought that stock would be better than what ive got now - would stock hurt the car w/out the air injection?

[tejohnson]

You will have an SES, may have some other slightly irritating issues... Gimme a ring this weekend, or stop by...

[tejohnson]

Oh, and for clarification... Did you put stock injectors back in? How about that rube goldberg mechanisim of a fuel system that ITS hacked in, etc...

[AaronGTR]

I wouldn't think you'd be able to load a calibration file from DHP with HPtuners. Not really sure.


Score one more for DHP though... with powrtuner you always have to ability to go back to stock. It tells you what all the stock values used to be so you can reset them. I would've thought HPtuners had something like this?

lol...i still have the bigger injectors in, but the fuel system is back in order to the best of my knowledge. the second fuel pump has been eliminated, the fuel lines have been redone.

Sure you can... All calibrations are the same. The big thing about going between HPT and DHP is the fact that not all the parameters are displayed the same way, and some of the tables are viewed & edited in different units of measure...

I completely agree...

Then stock fuel injector tables would make ya run excessively rich as well... In your case, completely stock is not really an option. Do you have your car back yet?

any pics of your old urbo setup

[tejohnson]

Used to be in this thread:

http://www.grandamgt.com/forum/showthread.php?t=41973

But I think all the links are broken now... In short, it was ITS work, and it was rather poor. The turbo they put in was too small, welds were crap, poor IC plumbing & routing... I could go on and on... It is a shame how they treated Donny...

[iceman]

Todd, you should have seen the first ITS setup back in '02... pics are on my site if you want them :nono:

You can load a DHP file into HPTuners, however, it can't be locked (and vv with HPTuners bins)

Going to stock is easy. For me, anyway, I read the PCM before I started modifying it (how did you start? DHP supply one?). I saved the first one as 'stock' and have about 200 others:)

I suggest this method for everyone, as some parameters can be changed otherwise (ie, by HPT or DHP directly without supplying the parameter; a quick fix). When d'loading the file from a stock PCM, it actually takes all settings, not just the few we can edit.

With the latest version of HPT, it has quite a helpful compare feature. I can open a corvette bin, for example and compare it with my GA (not that I would want to change the GA to a Vette, but pretty handy, nonetheless; MAF table maybe?).

I don't particularly see the benefit of storing the stock settings directly in the bin file as DHP does, but to each his own.

If you're interested, I've attached 2 screenshots. It is a compare of one of Todd's bin's vs mine.

The first file: The green buttons show the tables are different, the blue means they are the same. If a box was grey, it would mean the parameter is only available in one of the files. If the box is partially red, it means you have changed something, but not yet saved it.

The second file: I opened the spark advance table to show the 'difference button' It shows for example, at 800 rpm and .08 g/cyl, I have 9 degrees more timing than todd. If I select everything in the table and put in a 0 in the box, I can make my table the same as Todd's. You can select either table as well.

This could easily be done with the stock file.

Pretty helpful, IMHO.

Very true, the parameters are displayed very differently. When I was using a friends Powertuner, it took me a while to figure out how to change values...LOL

Regarding the different units of measure, HPT now contains the option to change the values from imperial to metric for each table.

There's alot of other 'nifty' things with HPT, but I'm already completely off topic. Sorry! I'm sure DHP is working on similar enhancements to their software, or it already exists. I'm just not brushed up on the functionality of DHP.

Well in my case when I got a powrtuner I already had a modified pcm so I couldn't do a read on a stock file. My pcm was customized by Dave Buckshaw way back in the day (2nd grand am they ever worked on, first a '99 then mine). :D I could still read the pcm though of course and I went thru it and it still had what all the stock settings where (don't know if these are in the powrtuner or what?) and I could see where Dave made changes. So with a powrtuner you don't have to have a stock pcm to start in order to revert to stock.

One neat thing the powrtuner does is make a change log everytime you modify and save a file with the same name. It gives a date and time and what you changed. Boxes in the settings you modify change to different colors depending on the % of change from stock the new number you enter is.

I guess at the time, you didn't have much of a choice. I'm sure anyone now tuning takes a backup before they make any changes to a stock bin.

I didn't know DHP had that history! That's definitely a good thing to have.

HPT has the history too, just not the % difference (at least I don't think so). I assume you can undo all the changes you made through the history, with DHP. HPT allows you to do that as well.

We should create a new thread with some of these differences so people can make an educated decision on which software to purchase.

He is one of the first (that I know of) HPTuners customers (started with 1.3.0)...

We were able to revert him, and keep some of the changes. It is nice with PowrTuner, because you can "import stock" on select tables...

I think he has a little more work to do...

I was going to say that my stock 2000 GAGT bin is up on the DHP forum. But it looks like you guys got everything figured out.

[tejohnson]

Well gee, that would have helped out a few days ago... lol

Have not heard back from donny since we flashed the PCM. He still had to get the EVAP purge re-installed which was making it awefull hard to do a case learn...

Could you email me your stock bin? xonelith@yahoo.ca

I'd like to get all year GA's (99+) stock bin's if I could.

Thanks,

I am not sure if you need it or not, but I have a stock 2001 BIN? Let me know if you need it and I will send it your way.

Not my fault you didn't check the forum first. It's only been up there for the last four months.

If you don't mind me asking, what is it for?

More of a compare between years and for interest sake. I've noticed, in a 2000, when someone asked me to verify some changes they made, many other things were different that most don't touch. Seems the stock bins are different.

I can view any bin, I just can't edit or load a bin from other than a 2001.

I will start another thread, for posting of stock bins. Might have helped in this case, if there was a thread containing them.
