Hey all, did a search, but I must not be entering the right terms. I was wondering if there is a complete listing of all the broadcast codes/bins for the gm tbi? You know, somehting that has the code/bin and what vehicle it was on? If someone has one, or the link to one, it would be greatly appreciated. i am converting my brother-in-laws b-body buick wagon to tbi, and want to get a caprice wagon bin for it.

Does it matter which ECM the BIN is from? Not sure if the wagons ever used the '8746, but they did use the '6965 ECMs. I have some PROMs here that I can read for the BIN.
Well, I am using the 7747 for this build, I had a few laying around. And if anything crazy happens in the future, i can add the EBL to it. So it will be a $42 mask, in a 7747 ecm. If I can transfer the timing/ve table from a caprice bin of a different ecm, that is fine too. I appreciate RBob.

I've been looking for the memcal based BCWW which is a 1993 Cadillac Brougham 350 TBI/700r4 for some time.

The '7747 was only used in trucks, not going to find a Caprice BIN for it. Here is the AYKC BIN. It was used in at least the '92 Caprice/Roadmaster wagons. MaskID of $62. Interestingly enough was used in both the 16136965 and 16135320 ECMs. Must have been a change in the ROM code.
It is for the 5.7l engine. I thought I had more BINs for the wagons.
Thank you sir, I appreciate it. I know the 7747 was for trucks, the 7746 was the car version? Anywho, I am putting the tbi in an 88 buick electra wagon, actually, a hurse. My bro likes death, lol. It has the buick 307 in it with the CCC system, emissions and all. I plan on retaining this stuff. I have been looking for a wiring diagram for the old CCC ecms, this way I can splice into the factory wiring for the brake switch, power, check engine light, etc.
I'll use this 350 bin, and change the things I need to put it on a 307.

Any other possibilities are appreciated.
RBob, as always you've come through!
I did a 1988 Cadillac, but there is little that can be retained from the CCC Setup. Other than the VSS. The check engine light works off of a light driver, that inverts the signal, it must be eliminated from the circuit for the SES light to work properly with the TBI ecm.
The 307 is an Oldsmobile engine BTW.
You can re-use the existing CCC Distributer, you just need to change the spark latency correction tables to match the large cap HEI, or the timing will be off at various RPMs compared to the small cap.
I would start with a 305 .bin. I have one that I used for my 307 hanging out somewhere, for the 6965 ECM though. The 6965 even controlled the factory A/C compressor cut-out relay and air divert solenoid.
This setup was not mine, but mine was very close. I used a 4.3 TBI unit (on a factory big block 454 TBI adapter), 305 ECM, and DIY tuned it.
I may not have the BCWW mask, but i do have a couple of ecms from fleetwood/roadmaster 5.7L engines, with memcals. I'll have to check. The caddies use a different ecm, BTW, has brown connectors on it, can't recall the number right now. PM your email, I'll pull the images off and send 'em to you.
It's funny, I'm in the middle of a similar project right now. 82 'bu wagon getting a fleetwood 5.7l with a '747(for now). I actually wanted to use the fleetwood ecm, but there is not much info out there for them. If you have any, I'd like to see what you've got.
Fast is right, you have to modify the SES circuit, and take out the driver module. VSS is re-used. You might have to trace out the IP connector in the electra, but I might have some CCC diagrams you can use. The nice thing is only few wires changed in the IP connector, and the colors were mostly the same, so it's not that much work to figure out. The hardest part is trying to remember where that SES driver module is.
one nice thing, BTW, if you find a caddy with the TBI, the fuel lines are nice, they run to the passenger front, and have a fuel pressure gauge fitting on them, it's a nice thing to use with a hybrid swap. Stainless too.
one other thing, as far as a G body goes, I dunno about the electra, a Chevy van harness uses the same firewall grommet that the old CCC does, so it drops right in, no cutting or anything. the harness ends up being flipped over, and about 9 inches longer than needed, but I just looped it behind the dist on top of the bellhousing. I'll snap some pics for you....
Thanks guys for the replies. Your right fast, had a brain fart on the 307, it's not a buick , I need to proofread my posts, .

Glad you mentioned that because I would have taken forever to figure that one out.

Didn't know that either, but then again I don't have a schematic for the car yet so I would have figured it out. I will be re-using the VSS, the SES light at least, make the circuit work. We ended up with a painless harness, with another harness for the emissions controls, I don't have that one in hand yet though so... I would like to take a look at than bin/xdf if you have time to email it to me.
I may have to go back to the jy to get the AIR pump control valve for the ecm to control.
jwscab, it would be grat if I can get those diagrams, I don't think the b-body is so different from the g-body in wiring pin-outs, beings they used the same engine/tranny combos. Have any pics of that bu wagon progress, mine is on my cardomain site, hehe
Yeah, my brother has been keeping a picture log of the progress so far. I've check out your site, since I noticed you have a wagon....very cool....nice job on everything. I have to see if he is putting them on a log or something.
I'll get the diags. as soon as I can. It's been pretty busy these days, so bear with me.
Thanx man, it's a work in progress. I have been feeling out suspension, engine, steering, etc. for the past 2 years. I've changed a few things numourous times. I wanna try out some turbo's the end of the year. I may even go LSx motor. But next year it is all coming apart for a frame off redo. I'd like to see your progress when you get a chance to upload your picture diary.
Fast, you are in luck, I have BCWW and BFYU, I'll pull the images off and add them here, unless you think it's better to just email them to you.(not original content of thread, really).
Liquid,
Hopefully, I can get the schematics today, they are at the shop, I'll be there tonight.

Fast - can you kindly provide a bit more information on this subject (spark latency and what it should be) . In my conversion I changed over from small size hat to full size CCC sourced dizzy, but made no other timing related changes. It may explain why have excessive knock detection between 1800 and 3200 RPM. (6965 with EBL)
RF, I plan on using the stock big cap dizzy, just gonna change the tables.
I also posted a new thread about the SA latency tables, and how they work. I noticed a tuned port small cap bin had a different SA latenct table then a small cap tbi bin. But a BBC tbi small cap had a different table then a SBC small cap bin. But they use the same dizzy??? I've been searching the web for 2 days now, more then a few hours, and can't find anything about it. Liek is there inprovements to be made moving those values up or down? If so, what does making the numbers bigger/smaller mean?
, I need to proofread my posts,
