does anyone know what this one is named?. I went to the dealer and they wanted 50 bucks just to hook up the scan tool to get the freggin bin number!. They want to charge me for a "computer code check & tune up" I know that's a load of crap. I told the guy all I want is the code number and thats it and he still said it'l be 50 bucks. I said no thanks.

If its the bin from your current car(which I'm assuming it is), just drop your computer from the dash and open the case to check for yourself. It should be listed right on the prom itself, under the protective blue memcal cover.

your ****tin me?. Hell thanks. Man I can't believe the dealer.

ok... I got delco BWAX 6865 and 2L2028... which one is it???? ok a few more... 16045915 AD27C256 E 5012AC U147003MC

[This message has been edited by Camaro_hunter_d (edited September 04, 2001).]

BWAX = BCC, the prom calibration code
6865 = scanner ID code? almost positive
and 2L2028.= no bloody clue on this one
16045915 = prom part # from GM
AD27C256 =prom part # so you can order a new one when you can't erase this one anymore..btw, I don't think GM sells them but electronic stores do.
E 5012AC U147003MC = other things I have no clue on

You don't need to find the bin on any site, you have it with you. Read the bin with your prom programmer.

I do not have a prom programer. I will not get one for about a month. I was gonna "fiddle" with the program to see what I can do to improve things a bit. I am learning this now so I was gonna do a little at a time and see what it does.


EDIT. SO first off I need to find a 6865? and with winbin find the BCC setting?... Thanks for the help though...

That's cool. It's always good to be prepared. But you have it wrong on the BCC. BWAX = BCC, the prom calibration code and the 6865 is the scanner ID code. What you want is BWAX. Find a file with this and read it with the editor. The scanner ID is in the prom code somewhere and you may even come across it with the bin editor.

OK... so go to DIY-EFI and get the Bwax file? then go throught the numbers in the editor till something is familar??? Sorry for all the questions but I am having one hellofa time finding this freggin bin...

ok is is whats goin on now... I have atty, atzy I forget which. I have the "clinder select" at 192=6(this is in the "values" tab. Does this mean this is the setting for the V6? I have the "prom setting" at 6865. I am still lost but am I at least making progress?

Could you give us some additional information. What are the codes on the white sticker on the ECM? This will allow us to identify it and possibly run an alternate calibration (like $8D with a 6 cylinder select).

But I need to see if you have a 7730. That is on the sticker. Just give me ALL the numbers on the white sticker on the ECM.

Also, what is your car? Year/model etc.

yes its a 7730. I wrote the numbers in another post that did not get much attention... I'll look around

Anyway its a 92 rs 3.1 5 spd.
EDIT heres the numbers
Comp numbers serial number 01227730 866651 M210192756

Chip BWAX 6865

I see no reason then why you can't just run a modified version of the $8D BIN for TPI cars. You MAY have to repin the ECM, but I don't think so.

The Cylinder Select should be x'C0 or d'192 as you mentioned.

You could start with a 305 TPI SD 5-speed bin to start and change the cylinder selct also to d'192.

Glenn, there are a few differences. Things like AC control, air valves, egr control. I have a wiring diagram somewhere and it had a few things changed. The major things are the same, injectors, sensors, timing, etc. I'm sure there is a wiring diagram somewhere on DIYEFI. If not I'll post one as I have access to them at work.

I think you should check that again. It should actually be a BAWX, not BWAX.

I am currently doing quite a bit of work on the 3.1 VIN T's, so the info I have gathered thus far may be of some use in your future endeavors. If anyone has any hacks, .ecu files, etc. for this application or other 3.1 V6's, I would welcome your submittal's to the gmecm ftp site. Already asked that a few times, but it cant hurt to try.
The bin you need can be found here:

ftp.diy-efi.org/pub/gmecm/bin_lib/1227730 727 01 A1 3E 46 51 55 6B 88 8D 96 D8/88/Bawx 88.bin

Note: You will need to access this with an ftp client in order to get the file, the directory name presents a problem with access via web browser.

I actually have the Factory Shop Manual for 91 Firebirds. I expect a 91 3.1 Firebird to be the same as a 92 3.1 RS. I will review the pin differences and try to identify as much as possible for future SD 3.1 users. I hope this is not going to the ONLY 3.1 user to dive into eprom burning. I's psyched just because Camaro_hunter_d has the balls to do it.

Since the ECMs are the same, the driver's for the other devices exist. As we analyze this deeper, there may be some of those that Camaro_hunter_D would like to wire up. Also, within the BIN, there is usually a some constant enabling the device based generally on coolant temp. This is how I turned off the AIR Diverter for a friend with a 383 Miniram and removed his.

Now that TunerCat has released their new verision that can support more constants, I can assist by defining more constants (old version limited you to 50 and I hit the max)and forwarding the changes to TC so everyone can use it.

PS: Yeah, I noticed that BAWX BIN too. I am going to scope it out and see if it is for a V6.

LOL thanks for the support!.(though I must say the biggest thing I am happy with is getting rid of the Speed limiter and pumping up the fuel saturation for more pick up.) I would like to get this thing pulling like it does in 3rd in all the gears!.


As for the other thing I have that big a$$ long named file already downloaded. Which one do I use in that thing????

Well, thats not too hard, just go here and type in the BCC:

http://holman.cs.uml.edu/~sdurphey/bccfind/

I think there may be a few more problems involved with using a V8 bin on a DIS 60 degree V6 than a simple change of the cyl setting.
If you look at the hack of the azty bcc, you will note that most of the tables locations differ greatly from those of the $8D V8.

I have already worked with the Turbo Grand Prix 3.1 code enough to create my own .ecu file, and it actually has a lot more parameters available than anything else I have seen thus far for the V6. The TGP code is much closer to the 3.1 Camaro/bird V6 than any V8 bin I have looked at. Just my $1/50, but starting from a V8 definition is not the approach I would take.

Ok cool thats the info on my BIN I quess? but where to download it?

OK why is it when I go to that GMECM thing I go to the '7730 and click it, but only the 2.8 V6 pops up? I would think that the 2.8-3.1 would be different. I see alot of 8d and what not... I take it these are the bin id#'s...

IF you have ftp client software (cuteftp, bullet proof ftp, etc) you can access the gmcem site and pullup the directory. Much of the directory structure of the ftp site will not allow access by web browser due to the naming conventions used. I would have just sent the bin file to you, but you do not disclose an email address.
The bin file itself would not be of much use without a definition (.ecu , .tdf , etc.) file. Should not be too hard to put one together tho, the hack of the azty bcc would be a very good base to start from.

Ok these sites are getting on my nerves something fierce. I can go to the FTP site through Gozilla. I STILL CANNOT GET THE FREGGIN 3.1 BIN. I CAN FIND THE 2.8. I am starting to get VERY pissed!.

I downloaded FTP explorer and I cannot connect to the site at all. I type in diy-efi.ftp and the screen goes blank. If any have the bin you can email it to me at emerald_iles@yahoo.com

done

I will have to look at this more too I was planning on burning a chip for my 2.8 6000

THANKS! THANKS! THANKS! THANKS! THANKS! THANKS! THANKS!... lol good greif thats a lot of junk to go throught to get a BIN!.

OK I got the BIN thanks to MIKE. But now what do I have to do to get the "PE" to kick in sooner?. I know I can set the RPMs for it but I want it to go more by the TPS input. I have a tendancy to cruise at 70-80 MPH on the highway so I do not want it kicked in while I am cruising.
How exactly do I get the timing to change to a less retard curve? And advance a little sooner?.

Should be a table PE vs TPS.

Remember more is not always better with timing. It's way to easy to be too rich, with too much timing and be slower then when you started.
