Hello Guys and Girls,i see that some members can build or burn chips (dont no much about the terminology) :) could someone please reply to let me no about how and who does these ,,thanks (1984 with automatic all stock ) :cheers:

The real problem is finding the correct chips anymore that will work with the stock ECM. That is one reason we stopped burning EEPROMs. Usually, you can't re-burn and a new chip is needed. If we could find reliable new chips we can burn 84 chips all day long with our mods which work great. Sorry, I can't help on the actual burning for you.

I'm very late to the game here and new the forum. looking to learn some about the 84 and programming the ECM. we have a manual, CFI. I made a ALDL cable and have downloaded the WINaldl software. the links in JoBy are not longer active. Does anyone have access to the .bin files?

IMO...If you really want to "program" your ECM, move to the EBL Flash II from Dynamic EFI and laptop tune your motor to your hearts content. If it's stock, I have the BIN file "tune" to give you for free. PM me if you want to go down this path. Dynamic EFI Flash II

What chips exactly do you need? Could you give me part #'s, descriptions, etc?

I do not have that info anymore since I don't do it and tossed everything a long time ago. They are the same chips as the early 80s arcade game EEPROMS though. Hard to find and when you do find them, most are bad and will not except a burn.

Yes I would be very interested in the .bin files. unfortunately I have not been confirmed as a member yet, so I cannot PM you, but I will as soon as my status has been updated and account confirmed. TY in advanced.

That's a bummer, thought maybe I might be able to come up with some. My family and extended family have been in the coin-op (amusement) business since 1955, my own father has personally repaired boards in just about every kind of video game/pinball machine made since the early 70's! He has an extensive parts inventory as well as connections all over the country for stuff like this! If you or anyone can come up with accurate chip numbers/specs, I would be more than happy to see what I can dig up👍
I remember back in the day I swapped in a 7747 ECU from a throttle body truck in my 84 and had a lot of fun with a chip burner. I think I still have the old burner and the chips for it if you really want them. The thing is though there are so many amazing aftermarket options out there that it hardly seems worth it. Go with a Holley ECU like the HP series or the Terminator and never look back. You can do live programming and data log. You can even control nitrous and have self learn with a wide band O2 so there is no need for dyno tuning if you swap cams. Even if you wanted something a little lower cost the mega squirts are a good option too.
Those E1 to E4 are different compared to standard EPROMS.
I used an Dataman s4 eprom programmer to read the stock chips as TI2716 chips using an adapter to handle those E-pins by connecting them to VCC and GND.
The 2716 chip is twice as big and has one extra adress pin, A10 but that is not connected when using the adapter.
By reading only the first half ( 00000-003FF ) HEX you get the chip data. If you read the whole 16k bit ( 00000-007FF ) you get the data twice. The second half will be the same again because pin A10 is not there.
It is almost impossible to get the correct N82S181 1k EPROM and I don't know how you would program it, but there is a simple solution to that.
To burn chips you should get EEPROM that are pin compatible with the 32k 2732 chip ( 4k * 8 ). It will work in the ECM without any adapter but there is one trick to make it work.
If you burn the 1k BIN data four times in a row then the status of the extra A10 and A11 pins does not matter. If I remember correctly it is the third area that will actually be used. ( 00800-00BFF ).

The BIN's posted above for L83 are all for automatic transmission. It would be interesting to get chip code and if you can extract bin file for the manual transmission.
My 1984 has a MaxxECU controlling everything now but I am acually working on a side project to see if I can get MPG-data back on the digital dash by using a microcontroller to emulate 160 baud data.
Using an adapter you could also use 28C64 EEPROMS but those are 28 pin. The adapter should connect pins 2, 26 and 28 together. Pins 3-26 go straight thru to 1-24.

WOW! Joby to the rescue. Ask and you shall receive. That pic brings back a lot of memories, the book in background I mean. I had their chip in my 82 back in 92/93 and worked ok with a somewhat mild cam. I still say that the EBL Flash II is the way to go on this 375hp motor and never waste my time with chip burning when you have the power of a laptop at your finger tips.

Hey the forum won't let me sent pictures in a PM so I'll just post the pics of the Eprom stuff I have here. I wish I had the disks for it.

@JoBy thanx for posting the bin stack info. Would offsetting the bin not work on a larger PROM? Ive used 28 pin EEPROM in '747 'puter tying 5 pins together on the zif before soldering into ECM like what Moates G2 would offer. Good stuff!
ACXT and APHP are BCCs for '87 '165 ECM. BCC Lookup xls https://xtronics.com/memory/updates.html Parallel printer port obsolete on most laptops. My laptop doesn't have one but the docking station for it does.

Yes, The pin layout match on the larger 28-pin EPROMS..
Pin 1-23 matches pin 3-25.
You should connect pins 1, 2, 26, 27 and 28 together on the DIL28 socket to get VCC from old pin 24 to all four extra pins.
You could ground pin 2 (A12) instead but the only effect would be that another 1k area of the chip would be read.
This is on my workbench now. My old 1226026 ECM with 28 pin ZIF socket for easy change of EPROMS. The extra pins are on the wrong side so I can not use a 28 pin chip in that. It would be quite easy to use a long legged chip socket as adapter for 28 pin chips. Just bending the legs and solering them together like I did when reading the stock EPROM. It would of course still be possible to use a 24 pin EPROM in that socket..
