the purpose of burning PROMs is to retain the stoichiometric 14.7 to 1 fuel ratio after modding your car..........am i correct?
so in other words.......your helping your car compesate more fuel for more air that is entering
but...............how do you figure all this out??
thats kinda where i'm left out
is it all done with the Block Learn tables?
i guess you can also control your spark advance, fan timing, etc.
but how much further does it go??
this is what is preventing me from going to TPI, by the way

Also, I found reading old posts really helpful. Yes, you are probably going to find a lot of "terminology" that you initially won't understand - but as you read more and more...a lot of it becomes self-explained. Also, some of it is not relevant or a "re-hash" of the same question that has been asked a thousand times. You quickly learn to close those posts and get the next one.
Also, you should click on every link in Traxion's article as they lead to even more info. Yes, there is a fair amount of information you have to initially read. But it's much like laying a good foundation for a building. Before you know it, the light bulb will click on and you'll understand the process.
In all honesty, the actual "mechanics" to burn an eprom is quite simple and you probably could be shown it in 15 minutes. It's the actual "tuning" that takes time - and sharing of information with others - which is what this board is really about.
My advice to you would be to go to the TPI board and read the sticky post at the top of the page that says TPS enhancer..........
Ed Maher puts everything in plain English that I know you would understand. You have to understand that the guys on this board are sick of answering the same novice questions over and over again.
Ask the simple questions on that board and ask the more advanced tuning questions over here.
I would also recommend downloading the tunercat demo and just look over all the tables. When I did this I had a much better understanding of what I could change and what was involved in tuning my car.
Also, if you are very adept at tuning a carbed motor and knowing what an engine needs you will pick up on this very quickly. You'll find it is actually a lot easier. Instead of changing jets in the carb and springs in the distributor, you can do it all while sitting on your *** in front of your computer, then just popping a chip in your car.

Actually, if people were to read the "older archives" from when the board initially begain, all "newbie" questions were answered in quite a bit of detail. That is why the "Intro" was written.

I hope that the Announcement: "Make sure you read Trax's Introduction to Prom Burning Article!" will be written with BIG RED WORDS in front of eyes of next newbiers when they are registered.
The article is very CLEAR: Read the article, search the links and read again.

Again, for a lot of people, they need to read this stuff a couple times before it starts to "sink in". Not too many read it JUST ONCE and have everything "click together".

I have to agree with everybody else. If you are not hip to what all the terms are, it can be extremely overwhelming when you first start to get into this. I have been working with cars for 25 years, and for the last 6 working with prostock stuff, and I didnt understand a thing about the computers 6 months ago. Just keep reading and keep searching the archives for terms you dont understand. Also, download tunercat or Winbin, and just look at what can be worked with. That way, you will see some of the terms that are used here, and see what everybody is talking about in the editor. 3 months b4 I got my car, I downloaded winbin, and Craig Moates' software, and just started trying to educate myself on them. I still keep refering to traxions into article, as there is TONS of good stuff in it. I also made a folder in ms word, that I will copy and paste all the good and useful info from the boards into. That way, I have a library of info that I dont have to worry about not being able to find when I want it.
I feel the best way to learn, is to just get in and try it. Make a copy of your stock info, and dont modify that. If you do something bad while tuning, you will still have a copy to fall back on. I actually keep all my bins that have been an improvement to the old ones, that way I can track what I have done. KEEP GOOD NOTES, so you dont get lost, and have fun, I feel the boundries are endless. Now if I could get a better grasp on the source code, I could really do something.

ok thanx guys............................i am going to mechanic school, but the only things they teach us there is: computer bad, throw out, go to parts department get new one.........LOL
either that or get out the TECHII and transfer files over from the PC
thanx guys

hey glenn, i just downloaded and setup WinBin
can you give me a BIN for my 91 3.1 MPFI camaro........its the only EFI car i have right now
its a 5 speed, BTW
maybe i'll try to program something for this............................

I don't have much info on V6 3.1s other than they use the SD. I have suggested in the past to TRY running the $8D code and changing the "Cylinder Select" to run for 6 cyls...but a LOT of V6 guys have jumped on my throat for suggesting that, so I have stopped any experimentation on V6 F-bodies.
But I am still willing to work with any V6 guy who is willing to give the $8D a go. I truly believe it will work if someone is willing to try it.
Alternatively, check out the V6 Board. Camaro_Hunter, and 89 have done some work and I believe that have V6 bins and ECUs for it. If they wish to "invite me" to their board and offer guidance I would be willing to help. But I personally don't have any "toys" for V6 cars.
Have you checked out www.diy-efi.org ?

Hopefully, it's a 1227730...but I've also seen different (for whatever reason only known to GM). Pull the ECM from under that dash. There is usually a "sticker" on it and it will have the ECM number AND the Bins' Broadcast Code. The BCC is usually a 3 or 4 alfpha followed by 4 numbers.

Yes, you NEED the BIN to edit it. You either have to get a copy of the bin (try www.diy-efi.org ), the V6 Board or you need to read the BIN off you memcal (you need a prom programmer/burner to do that). That is why I suggested "pulling" you ECM from your car and reading the sticker. Then you could see what the ECM readlly is (hopefully a 7730, but it might be something else) AND the BCC of the Memcal, so you try and find an exact copy at www.diy-efi.org . But often you need to "settle" for another variation. www.dif-efi.org has a copy of MOST bins, but not EVERYTHING. That is why suggest asking the V6 Board also.
I don't have a V6 Bin myself. (nor any ECU files for WinBin...I use TunerCat)

ok, Glenn
i finally found the what i believe is the correct BIN
now, i am just a little consfused with how to adjust things in the "values" area
whats the Raw Hex/X Label mean.......???? i dont understand that.....
otherwise doesnt seem all too hard
thanx glenn

But what you are discussing is the "actual binary" value stored in the BIN usually have a range of values from x00-xFF (d0-d255). There are "alogrythms" that are used to convert these "Hex" values to (say) Temperature. If you read Traxion's article and go to some of the links, you will find some of those algorythms. That is why I like TunerCat - all of that is done for you automatically. I only have to change a value to the proepr Temp, RPM, MPH etc and never worry about that actual "Hex" value.

do you know how to translate the binary "hex" figures into normal values?

I don't know how much you value your time, but I value mine a lot. To use Assembler or WinBin for ALL my changes is just too time consuming. I have better things to do, like ANALYZE the results. Not make a bunch of changes and figure out "Now what is 183*F in Celcius, and what was that formula for Celcius to Hex"?
Yeah TunerCat costs $70 and the TDF for your particular application is another $20. But the time it saves for me to do things is PRICELESS.
Now, if you CAN'T find a TDF for a V6 application...TELL THEM TO MAKE ONE! If TunerCat was aware of the number of V6 guys that WOULD be interested in a TDF for the specific V6 Bins for F-bodies I think they would make it. They JUST made a TDF for 2.8 V6 Fieros. So if they can do that, then they should be able to make one for V6 cars.

The translation is as follows:
Decim. /Hex
values /values
1 = 1
2 = 2
3 = 3
4 = 4
5 = 5
6 = 6
7 = 7
8 = 8
9 = 9
10= 0 (On 10 basis)
11= A
12= B
13= C
14= D
15= E
16= F (On 16 basis)
17=11
18=12
... ...
... ...
... ...
31=1E
32=1F
33=21
... ...
... ...
Some typical values:
FF = 16x16 = 256
256/2 = 256 at exact middle = 128 (BLM = 128)
FFFF = 256x256 = 65536/8 = 8192 (8192 Baud rate).
Very easy, or not????.
