Hi guys! After reading and researching for a few days, and buying some hardware over time, I'm finally ready to burn my first chip. I'd like to start by burning my own stock chip for my 88 305 TPI auto. I don't want to read it from my stock MEMCAL because I don't want to risk damaging it. In any case, I've been going through a ton of searches and looking thought the Moates files and diy-efi files but I can't find one that fits exactly. The closest I believe is the 86TPI32 but it does not specify if automatic or manual. I think it should work and I know I can flip it to auto if manual but, again, I'd really like a fresh, untouched bin to begin with. So, out of this list I found on Moates.net, which would you suggest is the one for what I want:
86TPI32.bin
88CORV32.bin
88VETTE32.bin
89FBA35032.bin
ABTB0315 32.bin
ABTM 32.bin
ABTP 32.bin
ABTR 32.bin
ABTU 32.bin
ABTZ 32.bin
ABWW 32.bin
AMJ 32.bin
ASME516O 32.bin
AZSP 32.bin
Aanl4045 32.bin
Aanm 32.bin
Abtd 32.bin
Abtf0735 32.bin
Abtr4763 32.bin
Abuamt 32.bin
Ama8848 32.bin
BUA1728 32.bin
BUA9340 32.bin
Bua 32.bin
Bua2 32.bin
abtc 32.bin
abwt 32.bin
abwt88ta 32.bin
acxs 32.bin
acyc1135 32.bin
akfm2174 32.bin
aum0122 32.bin

Thanks.

Use the broadcast code from your original memcal to find the bin BBC code. To find a Bin you need the gear ratio, Vats or not and auto or manual. also I believe some late 88s had 9th injector deleted. they are all different. All of the codes above look like modified bins. make sure you get a stock bin to start with. Reading from original Memcal will not damage it because it takes a UV eraser to erase the prom and you cannot write to a non blank prom.

galletti

Thanks for your quick response. What I meant by not damaging my stock prom is that I don't want to desolder it from the carrier. I just ordered an adapter from Moates that will allow me to read it with my BURN1 unit. That will solve my problem but I was wondering if I'd be able to find the correct one online. If this will help, my car is an 88 (so no VATS), with a 2.73 rear, auto trans, and 9th injector in place. In any case, I'll start searching for how to get the broadcast code and BBC code.

AKFN is the one you want. But I can't seem to find it either. Most have converted to the 89 bin without the 9th injector which is probably what you should do also but you would have to unplug the injector or it will flood on start. check this site out:

http://www.gearhead-efi.com/Fuel-Inj...ge2&order=desc

they have a lot off bin and definition files. the closest is ACXS which is for a 87 with your gears. It is listed under 1227165 ECM information - $32b.

The original BBC should be on your Memcal and/or on the ECM.

galletti

Thanks again! I decided to pull my ECM and on the chip it reads AKFM but I can't find that either. I appreciate your recommendation. My car is about to undergo major surgery under the hood and I already have the 9th injector elimination kit so I'll probably go with that. Again, I appreciate your input.

You are much better off reading the stock PROM. This way you know that it is stock.

Note that GM also used 256kb PROMs with the 128kb program in the TPI MAF cars. So you may need to read the top half of the PROM.

galletti

Actually, AKFM is next to last on the list I posted above. I'll go grab it!

galletti

I was able to read the Stage 2 Jet Performance Chip and save the 16k bin using my BURN1 and TunerPro RT. I figured the formats would be much the same. I'll see what happens when I get my adapter and try reading my stock bin. I'm actually running into a hardware issue now since my BURN1 is giving me an I/O error when I try to burn a stacked bin to a 29F040 even though all troubleshooting went ok. But that's for another thread.

Those bins probably are modified and based on their listing number probably are for different ECMs. Follow RBOBs advice. Read your memcal. Not sure if 29F040 is a valid eeprom for the ecm and burner. RBOB will know that.

galletti

Duly noted. I'll read from my MEMCAL once I get my adapter. In the meanwhile I'm messing around with the mechanics of getting a chip working (hence the stacking and burning). According to the Moates site, that list is for stock bin files but you never really know, do you. Also, the 29F040 is definitely compatible with the BURN1; I double checked on the Moates web site. I emailed them about the error message.

I know Moates lists it that way and they may be stock, I just don't know what the extra numbers are for. Also I think it is a mass download of files from this site http://www.diy-efi.org/gmecm/ so it may just be how they are listed. Good luck with your programming.

The 29F040 is compatible.
If you use the G3 "switcher" adapter you can store a bunch of bin files on there.
I like to experiment with an item and have bins made that progressivly increase or decrease a value. Then when driving I can safely change the bin and basically tweak the value until I find what works best.
Make the change on my "running" bin and then try something else.
Keeps my eyes on the road and not the laptop as much.

I use a 32K bin and it holds 16 bins on the 29F040, yours being 16K would still hold 16 bins and just use the upper address space of each 32k slot so to speak.
If you only put 1 bin on that chip it must be located at the end of the chip to run. See the notes on that on Moates site under chip offsets.

galletti

Thank you and Thank you. The response time and willingness to help here is truly amazing.

looks like he just got the same list as here.. ftp://ftp.diy-efi.org/pub/gmecm/bin_...%206E%2094/32/
if thats the case it should be stock. I may have a copy of one of my chips but id have to do some digging around

galletti

Yes 88. I read an old thread on here about how a lot of Moates' files came from that database. It's great these are around in several places. I was able to get the file but haven't looked at it yet. I'm a true beginner so there's little I'd be able to tell was changed but it's the closest one I've found. I agree with utilityguy that It's strange it has the numbers following though. We'll see.

AKFM is here under bins.

Hi everyone! Just thought I'd let you know, I finally burned my first successful chip! Granted it was super basic. I read my stock AKFM, burn onto a 29C256 as my 040 appears to be damaged. I put the chip onto my G3, my stock MEMCAL on the piggy back and back onto my ECM. Voila! Running car. I had actually done something similar to this with the JET chip I had but had committed the following errors:
1. There's not much to burning a 16k bin onto a 256 chip. Burn program actually sets the offset for it. I'd tried with different stacks and nothing worked. I've yet to figures that one out.
2. The orientation of the chip in the G3 is actually the reverse of what it is on the zif adapter on the BURN1. I'd previously put the chip in the same orientation hence no go.
3. Jumper settings on the G3. I'd neglected to change them when I went with only one file on the chip.
I'm doing this in baby steps (What About Bob?!). My next step is to burn a chip where I can pick between stock and JET chip bins. The next one is bigger. I'm switching from MAF to MAP but will research more as my questions list for that is longer (what bin to start with, which MEMCAL do I piggyback, etc.)
Thanks again to everyone who had some input here.

Good Job! By the way, how many pins does the 040 have. I thought it had extras that you need to hang over the end of everything. May be wrong. But was something different about that chip, just don't remember what.

galletti

Thanks! The 040 is a 512k chip. I don't recall offhand how many pins it has but it fills up the zip adaptor but nothing hangs off the end. I'll let you know how it goes with the dual chip.

utilityguy2

iTrader: (1)

That's what I'm thinking. It has extra pins so you cannot program it by putting it in the ZIF fully. I think I read somewhere you need to hang the extra two sets off the back not in the ZIF. Maybe that's why you had trouble with it.

galletti

Very interesting. I'll check on that.

I found the 29f040 is a 32 pin chip whereas most others are 28. I know the G3 takes both with the 28 pin all the way to the right towards power connector. But it still sticks in my head something about hanging the 4 extra pins over the back of ??? Was it the burner ??? Maybe someone else can chime in?

galletti

Right. In most instructions to use a 28 pin chip in a 32 hole socket (ZIF adapter on my G3, APU1, and BURN1), they mention to keep the 4 empty holes to the side of the lever on the ZIF. I think this is what you are thinking of. There is no way to "hang" four pins on the 040 chip from the end of the ZIF. Also, I have thoroughly searched the Moates literature and can find no reference to this.
