NEEDED: 16197427 5.7L Manual Trans bin

[EagleMark]

Anyone have a clean stock 5.7L bin for a 427 ECM conversion?

[RobertISaar]

i don't believe you'll find a "stock" BIN..... IIRC, with the manual trans models, GM was still using an older ECM.

[EagleMark]

Yeah that's what everyone thought and would make sense then a manual bin file popped up! Man I wish I remember where...

[EagleMark]

But if I can't find one do you think I could just zero out all tranny paremeters in a auto bin file?

[RobertISaar]

knowing GM, there's a code switch that would take care of that, but you would need to adjust other things, mostly IAC related.

[Nasty-Z]

I would be interested in a '7427 manual .bin as well if it is found.

I started with BJYL, which is a 5.7/700R4 .bin, for my S10 434/Tremec project , worked out O.K but still "idle hunts" from time to time.

[EagleMark]

93V8S10 on TGO said he found some manuals at Moates but no V8 ones? :sad:

So it looks like maybe the export BCC to start and import some 5.7L paremeters.

BHFM, $0D, 1994, S1, PFI 2.2L L4(CAL), Manual, 8505
BHRD, $0D, 1994, L1, CPI 4.3L V6(FED, ALT), Manual, 6395
BNBJ, $0D, 1995, L1, CPI 4.3L V6(EXP), Manual, 7427

[EagleMark]

16196396 ECM
C/K 1500,2500 - BDUY, BDUZ
C/K 2500,3500 - BDTR

and BHNB or BHNC are supposed to be 427 BCC manual trans for CAL because they needed the EGR pintle...

[gregs78cam]

I would just start with any $0D bin that looks close and change the flags for TCC, shift light, Electronic shifting, and what not. I guess there are also some idle paramters used only for Manual Transmissions in the Advanced_$0D_TP5_v250.xdf. That '7427 is one very versatile PCM. I am getting a pretty good handle on this tunin' stuff, let me know when you plan to start tweaking it and I could probably find some time to come by and help.

[dave w]

The 7.4 liter $OE BHDC bin file is manual transmission.

dave w

[EagleMark]

Since it is going to need a full tune anyway I was just trying to find as close a match as possable to start. It's going on my sons 5.6L IH Engine we are rebuilding now, bottom end almost done.

I think I will take both your advices and see what works best. I know that manual trans bins and engines before bins that had toilet bowels, ah I mean controlled fuel leaks/carburators had some form of decel valve as to not let throttle snap shut between shifts. This is why I wanted to start with a manual bin.

From looking at defs made for this ECM/PCM the $OD does look like the most advanced but I did not see any paremeters for the manual shift decel valve situation, is another reason I wanted to start with a manual bin file. Sure lots of auto tranny choices and ons and offs, but no maual decel stuff... it may be there and work fine, all it does is slow the rate of decent of RPM between shifts. I beleive this was first installed as a emmissions device but ended up being a advantage to driving a manual trans.

[RobertISaar]

i would think the IAC throttle follower would perform that function.

[gregs78cam]

Yes, throttle follower is used extensively with manual trans, But there are some dedicated idle routines to handle a manual trans. In the .xdf there are some tables that state in the description they are just for manual a trans. I think they are near the bottom of the tables just before the 4L60E stuff.

[EagleMark]

Well good! Then I should just start with a 5.7L anything $OD Right? Wonder if they have a BCC for export? I have heard they run better than the ones for CA or FED. With as many options as there are with $OD I guess it doensn't matter...

[dave w]

I've done six '427 type PCM's upgrades / conversions. For a Manual Trans and Non TCC Auto Trans (TH400 / TH350) I like $OE. For the 700R$ Auto Trans I like $OD. I attached a copy of the $OE BHDC.bin I've also been working with Excel, learning how to Record a Macro, so I can sort the data logs for both Near Idle / Off Idle tables.

dave w

[gregs78cam]

Dynamic Spark parameters are the ones that I was thinking of. I also meant to add to my last post that on my '98 Grand Am with a 5 speed, the throttle follower action is very noticable. $0D/$0E have 16 throttle follower scalars, 5 tables, 8 dynamic spark scalars.

[JeepsAndGuns]

So your FINALLY gonna start on this? :laugh:
I have been reading about this for months now wondering if you were ever gonna put it in. :innocent2:

I will finally have another person running the 7427 with a manual trans. What bin you gonna start with?

[EagleMark]

Yeah, me too?

BMHK $OE it's the only manual bin I ever found, is there another one? Think it was your thread that confirmed what I was taught about bins a long time ago from auto to manual having lots of changes not normally seen in simple xdf or software like TunerCat. Guys who can dissemble can find subtle differences but the new XDF v250 stuff has found so many parameters and TunerPro compare function confirmed many differences in IAC logic to begin with.

[JeepsAndGuns]

Thats the same bin I am using. I'm sure there are probably others, but this one seemed like the easyest one to find.

[JeepsAndGuns]

Only one I know of available too?

[93V8S10]

BHDC is also manual.

[EagleMark]

BHDC is leaded fuel, Export open loop! And a 7.4L..

EDIT: I was wrong!

BCC Find says without NM8 leaded fuel. So I went back and looked in Cal Data and it has a "-" sign in front of NM8 which is RPO code for leaded fuel. So I was wrong it is not leaded fuel which is always been open loop.

Checked the BHDC 93V8S10 said he has and same thing "-" NM8 so that is also a good bin with no superceded number and would ba a better start.

So I guess it was origanally for leaded fuel under another BCC then just used for closed loop. Weird how Cal Data says "-" and the emmisions catagory is just * ? These 7.4L manual was heavy a commercail truck to start...
So I'd like a copy of that bin please! http://www.gearhead-efi.com/Fuel-Injection/images/smilies/rock on.gif

[EagleMark]

BHDC is leaded fuel, Export open loop! And a 7.4L..

[93V8S10]

Aaa thats no good!

Been looking through some of my bins, though I had others, but there all auto, except for two. :(

[JeepsAndGuns]

BMHK is for the 7.4

[EagleMark]

I think I remeber that but I put 5.7 VE tables in? Or changed cylinder size and injectors or something back then...

DAM, just looked at BMHK in Cal Data and it is 7.4L leaded fuel, Export too! And superceded to BPRJ... :mad1:

You got it to go closed loop right?

[1project2many]

I'd use a big block cal to start. IMO it's more appropriate for tha big old iron intake and block with slow burn heads. Typically the open loop cals only have the closed loop enable temp set high. Everythign else is usually copied from a stock calibration. Change the CL enable temp and you're good to go.

[JeepsAndGuns]

Mine goes closed loop. Actually it went closed loop WAY sooner than my old 7747 did. I have actually raised the min temp for closed loop just a bit. My engine likes lots of fuel when cold, so keeping it in open loop and a tad rich helps it lot when cold. I think I raised the temp to 100* F.

Your BCC lookup says:




Without NM8 EMISSION SYSTEM, LEADED FUEL

[EagleMark]

Everythign else is usually copied from a stock calibration. Change the CL enable temp and you're good to go.Looks like that's true for this $OE type stuff. But we found a $42 export leaded fuel bin that guy changed all those options and never got closed loop? I've helped a couple guys over seas with export open loop and was easier to just start with new bin, lots of other changes! One guy can't get parts in Iran and he's working on these changes now.

There is a copy of BMHK and BHDC in this thread:

:innocent2:

[93V8S10]

Actually, you already have it in the $0E thread.

[1project2many]

That's GM's coding straight out of the database. +NM8 = With leaded fuel. -NM8 = without leaded fuel. The key is that calibrations that are California or Federal Emissions certified for light vehicles have to be "-NM8" so the option code isn't usually included. But 8600# GVW and up are not "federal emissions certified" so the NM8 option is listed with the plus or minus sign. BMHL, BRCZ, BDTR, and BDWB are all manual trans, open loop calibrations if you'd like to do some comparing.

[1project2many]

Looks like that's true for this $OE type stuff. But we found a $42 export leaded fuel bin that guy changed all those options and never got closed loop?

Do you have a copy of this cal? I'd love to take a look.

[EagleMark]

Yup, it's clearly marked in the $42 ECM information thread. Was there as regular bin but brought to my attention by dyeager535 so I renamed it.

[EagleMark]

Actually, you already have it in the $0E thread.Thanks! :thumbsup:

Not really interested in open loop bins at all. Just thought if I could find a 5.7L Manual bin it would be an easier start. One I have and Jeepsand Guns is useing was superceded, one 93V8S10 brought up was not but both are 7.4L manual. One Gregcam has comes up as 5.7L Manaul from a 16197427 PCM but he says he pulled it from 5.7L 4L60E. So I really don't know wha tto start with. I know for a fact Manual bins have way differant settings, mostly IAC logic then auto. So manual bin, none superceded from 7.4L and make adjsutments then tune seems to be best start?

Haven't looked at this yet from Greg...

[1project2many]

Does BPRW have the manual bit selected? Any shift light parameters used?


I don't usually worry about getting the latest .bin. Many of the 93-95 cals were superceded to decrease cold spark advance to hide piston slap that developed as the engines aged. Big deal. Others have small changes such as slight increases in idle rpm or TCC engage / disengage speeds changed. Most of the cals we use are going in apps that are so far from stock it's not going to matter anyway.

[gregs78cam]

Manual Trans, Shift light, Stall saver....no, no, and no.

Shift light constants and tables do have data, but so do the 700R4 stuff. It seems to me they set this up from the factory with data to run anything with just a few bit changes.

[1project2many]

More than likely they were just like we are... started with another working cal and modified it as needed. I've seen some cals done by GM engineers "in the field" and it's really simple stuff. BLM and INT limits are set to provide a huge correction window, rev limiters raised but no corresponding changes to fuel or spark. Closed loop disabled and AFR's set around 12-13:1. Nothing official, and nothing condoned by GM but a good way to make an engine run without looking like an amatuer.

[jim_in_dorris]

Okay, I missed a 94 350 manual transmission 4x4 Z71 truck that a friend sold that would have had a manual bin in it. D@@@ it. Anyways I used the moates BCC lookup spreadsheet and filtered it for 427 ECM's with 5.7L and man. trans. and it shows BJYN which is in MOATES file managers as a 95 full size van 5.7l with a 4l60E modified bin. All the other BCC's aren't in moates. i am going to go try the BCC Lookup link now.

<EDIT> Okay, the BCCLookup has them all as automatics. There is another Z71 in town at a used car lot, I will stop and see if it is still there, and if it is a manual, will try and talk them into letting me see what the BCC is. Otherwise I don't know if I can locate the friends old truck as it was sold out of the area.

[gregs78cam]

You got me thinking, so I started looking, would any of these trucks happen to have what you are looking for?

[jim_in_dorris]

The 1st, 2nd, and 6th are exactly what I was talking about. It sure would be nice to know what BCC's they had, and even better, a copy of one of them to add to the collection. I just looked, none are listed in Klamath Falls.

[gregs78cam]

No but I just might try to get ahold of the owners and ask if I can read the memcal.

[JeepsAndGuns]

What ecm/pcm should those 5 speed trucks have? 6395?

[EagleMark]

BJYN in Cal Data shows 5.7L Manual 16197427 (superceded to BPSA and differant PCM 16156930) so I thing the BCC Lookup spread sheet is same database as CalData.

On BCCFind it says Trans Type= all/no listing just like the other one gregs78cam posted and he swears it came from an auto truck. CalData shows it to came from PCM 16156930 but it is in 16197427. So maybe GM did not had learned by then how to have a bin for both? By seeing 2 of these now I'd bet the 16156930 PCM is missing a few pieces needed for auto trans?

[JeepsAndGuns]

Sounds like the only way to truely find out is going to be inspect 94-95 350 manual trans trucks. Mabey find some way to sweet talk the owners to let you see what pcm they have, and read the bins.
I checked craiglist today, no 5 speed trucks of the correct year range in my area.

[gregs78cam]

there is that one at the car lot, I should go over there and "take it for a test drive":innocent2:

[jim_in_dorris]

wow, that's an idea. It would be truly awesome to add that bin to the knowledge base. I would be willing to spend time looking at the differences between it and an auto bin.

[EagleMark]

Look in the other thread, there is a V6 Manual there and plenty of V6 autos around for $OD. No one has found a 5.7L manual bin yet, found some 7.4L manual for $OE.

[jim_in_dorris]

Mark that's my point, I know that there are 5.7L 5 speed trucks out there, I have personally looked at buying one, and if I had known that there aren't any documented BCC's for that combo, I would have convinced the owner to let me look at it anyways. If Greg can "test drive" the local truck at the lot, we may have a first. Even if it wasn't anything except a bcc, we would know for sure that that BCC belonged to a 5.7L manual truck. I would really like to see that happen, even though, as you point out, there are 4.3 5 speed bins available. Converting a 4.3 to a 5.7 bin isn't quite as simple are injector constants and cylinder displacement and # of cylinders, because i bet that 5.7 manual spark tables are different than 5.7 auto spark tables.

[1project2many]

Seems like we've got three threads covering the same thing! The 93-95 5.0 / 5.7 pickups used a C3 ECM. They didn't use the 7427 family pcm. I was in Montana at a GM dealership from 91 - 98 which is the heart of truck country at a time when these trucks were new.

Now here's a neat trick for yall. I grabbed a VIN from a craigslist ad listing on Google:

Dec 28, 2011 – 1995 Chevrolet K1500 Red Manual 5 speed - $5900 (Greenville) ... Vehicle Information. VIN: 1GCEK14K7SZ218078, Trim: Miles: 178000, Color: Red. Engine: 8-Cylinder 5.7L V8 TBI OHV 16V, MPG: Stock #: 071 ...

Then I headed over to the Delco TIS CalID lookup site (http://tis2web.service.gm.com/tis2web) (<- linky) and entered the VIN so I could directly access GM information for the latest calibrations. TIS asks the following questions:
Automatic / Manual (manual, of course)
Altitude / California / Federal / Export emissions (start with Federal)
then it asks
ECM #
16188910 BDUY
16188913 BDUZ
16188922 BDWB

So I now have three BCC options. If I were still at the dealer I'd probably know if any of those ecm part nos are current versions of the 7427 family but I can still head back to BCCFind and see if they're listed:
All of these cals are for the C3 ECM.

You can try this trick with other VINS. I don't know the extent of the database coverage. GM might have dropped support for some of the really old stuff.

[EagleMark]

Converting a 4.3 to a 5.7 bin isn't quite as simple are injector constants and cylinder displacement and # of cylinders, because i bet that 5.7 manual spark tables are different than 5.7 auto spark tables.I understand that but for me anyway it's going in an IH 345 engine, I have a tuned spark table for that engine, also a tuned VE Fuel table, but both are from 1227747. Point is it will be tuned anyways.

The differnces in auto to manual are huge and not always seen in available xdf/ecu files. May be they are in these new v250 $OD stuff? But there could be 100's of changes that have to match. Like IAC in auto, well driving an auto you touch gas pedal and stay there. Manual you accelerate, let off, shift accelerate rinse and repeat. Lots of differences in IAC logic not only for emmissions that increase when you decelerate but in ease of shift, which was a side effect of the decel valve on manual trans carb cars when they installed it for emmissions.

This is where my search started and was told there was in CA do to there emmissions regulations 5.7L needed the linear EGR valve so they needed the 16197427 type PCM. So CA would be the only palce to find one unless the CA truck moved cross country...

[1project2many]

Mark, I've never seen a 7427 + 5.7 + manual trans calibration. I listed all of the cals available for 7427 family and manual trans in the other thread. The only search I haven't done is for manual transmissions plus the early 6930 pcm number which I'll get to tonight if I can. FWIW when I went back through the TIS site and picked Cali emissions, it listed BDUY.

[EagleMark]

Search has been extensive so I doubt there ever was a 5.7L manual bin for 16197427 and $OD?

BDUY comes back for ECM/PCM 16196396 which I have no info on what it is or replaces?

So I guess it boils down to best starting point. 7.4L manual for $OE or 4.3L manual for $OD.

I am leaning towards 4.3L Man for $OD because it's $OD but engine constants are all filled in so I don't know how to check if it was TBI or CPI?

But engine design of old IH may be closer to 7.4L Man in $OE which was TBI...

Any choose will need to be tuned so I am just trying to start with better choice.

But don't want that to be an end to what has turned into an ineresting and informative thread. :thumbsup:

[jim_in_dorris]

I headed over to moates and looked up the 6396 ECM, it is a $9A mask. They actually have the source code hack for BDUY. Even without knowing assembly coding, you could see all the table values for modifying a $0D file, It might be interesting to compare them. I downloaded the files, and may take a look at them this weekend. Since I don't own a truck with a 5 speed, I really don't need an XDF for it, but perhaps a need will arise for someone in the future.

[EagleMark]

I looked throught the TunerPro Lookup and I have a $9A XDF. it also says 2732 for the chip so I think that's back to a C3 ECM...

Just for refernce there is more on this subjct here:
http://www.gearhead-efi.com/Fuel-Injection/showthread.php?558-6395-7427-8625-Manual-Trans-Calibration-Listing

[1project2many]

6396 is a C3.
4.3 truck manual cals sometimes did "funny" stuff with throttle follower hanging open long after clutch was pressed in and idle speeds higher than V8's. Not hard to correct, just good to know ahead of time.

I like 7.4 cals for old engines with big slow burn heads and large intake manifolds. I've even used a 7.4 cal as a base for a Jeep I6 with TBI conversion and it worked way better than original vendor's 4.3 based cal.

[EagleMark]

So at this point I think I am sticking with 7.4L Manual $OE bin since I've done a lot to it already in preparation for start up, actually even burned a 27Fs512 chip for G1 Moates adapter. Harness is going in today, been tinkering, collecting parts, etc... this week.

Have stock fuel lines from TBI truck we are going to run back to tank. Greg is coming over with a bucket type in tank pump that may work, it's a very short unit he says. This tank is only 7-8 inches tall, not to wide and very long!

[JeepsAndGuns]

Any updates?

Also, do you know if the 7.4 uses a speed sensor, or are idle functions all controlled by the software? I'm in the planning stages of a TBI conversion on a 350 with manual transmission (and no speed sensor) and I would prefer to use a P4 ECM. The one (only?) benefit of a C3 processor is that bin's are available with dedicated idle routines for a manual tranny.

[EagleMark]

Not really?

There is no 5.7L Manual bins made for 16197427 any mask, they were different ECM. There are 7.4L manual bins for 16197427 $0E and that's what I used. Very easy to change to 5.7L.

It runs very well without VSS but I would not recommend it or do it again, to much work but I wanted to prove it could be done because a butthead somewhere else said it couldn't. We have also come up with theory of easier way, but untested theory only. VSS can be added to speedo cable for around $75. from couple different places.

This is good news for me! I'm new to TBI and still in the learning stage; I was concerned that editing the 7.4 bin for use on a 5.7 would be more "reprograming" than tuning.

Why do you recommend against not using VSS? What problems does it present? I know that I could add a VSS, but I have a Classic Instruments electronic speedomenter and 16 pulse sender. To use VSS I would have to pitch the sender, buy the VSS and then a digital signal converter box for about $100 that would allow the speedometer to use the 2 pulse VSS signal

[EagleMark]

Fairly easy to change an $0D, $0E etc... bin to differant size engine. The bin itself is fairly complex as to idle and off idle tables! Most of which are speed based along with TPS%. Every EFI conversion I have done without VSS was better with. $0D/$0E was the hardest to make run and drive without side effects because of no VSS!

I've never dealt with digatal speedo issues? But why can't you just add another VSS? Why not put 2 in a short speedo cable? Or wonder if the VSS signal you have can be split? It can be adjusted in bin...

I'd never attempt to run these PCM again without VSS, way to much tuning work for $75. I tune live with AutoProm and I'll bet I added 6 hours to a simple tune because of no VSS.

I posted a similar question in the TBI forum on TGO and received the following reply:


That's not true - surprisingly P4 PCM was used with LO5 and manual trany in G20 and G30 vans and step vans. Partial list of calibrations provided below.

Word of advise - P4 PCM can be used with any trany (MT/THM350/700R4/4L60E, 80E). You may need to incorporate SA and AE changes into a baseline AT bin file to make PCM play nice with a manual gearbox.

I can't vouch for the accuracy of this information but thought I would share

I've seen that and others but none ever panned out. Like BJZP does not exist in Cal Data and says it's an Auto in BCC Find?
http://www.gearhead-efi.com/BCCFind/result.shtml?BCC=BJZP
BJZH is an Export (open loop) that has been superseded to one that has no info? BJYZ is one we thought to have a good story as the 16197427 PCM was needed for Cal emissions because of pintle EGR, it is superseded twice to even a different PCM?

Others have said to be 5.7L Manual but when looked at they were Auto, like BJZH in BCC Find:
http://www.gearhead-efi.com/BCCFind/result.shtml?BCC=BJZH

Every bin I ever checked was an Auto bin and did not even have the Manual bitmask checked.

So let me rephrase that, they may be there but no one has yet to see one? So maybe if we can find a G20-30-35 manual stepvan in Cal from 1994-95?

Have to remember this was state of the art PCM designed for Auto Trans, why would it be used in a manual? I think OBDII was coming and GM ran out of cheaper ECMs and used up what was left? Just a theory... along with pintle valve EGR needed for CA emissions, again just a theory, no proof or bin yet.

Anyway it's to easy to make another Manual bin work in these PCM, unlike C3 ECM bins which are readily available to start with. 4.3L or 7.4L Manual = available and EZ.

I gave up looking for the ghost bin...

I know this is an old thread.... still looking for a 5.7 with 5 speed? That is my 1990

[EagleMark]

1990 would be the wrong ECM...

[CenTexBiker]

Isnt the code same for 7747 and 7427. Sorry i am a noob

[PJG1173]

no very much different.

[CenTexBiker]

no very much different.

So why dont they want it? They have been lookung for 2 years.

Alao maybe you can help: the bin from the L05 export with manual, will that work as an update for a vortec with tbi?

[EagleMark]

The one you have is for a differant ECM. Each ECM/PCM has differant code called a Mask, otherwise known as an Operating System. So it won't work in a 16197427 PCM.

Don't start with a bin marked Export. These were exported to countries that had leaded fuel and can't run an O2 sensor so they are always Open Loop.

[CenTexBiker]

Aahhh gotcha. Thanks for the info

[corvetteracing]

tell me please what if any works or what BCC & platform & ECU & program ID and dose it use 27SF512 chips --BPRM /G2/16156930/$DO---BPRX /G2/16156930/$DO---states 5.7 /man/3.73 "GT4" gears thoughts input thanks.

[corvetteracing]

hay there where do you find the above >bin files
I cant find them .thanks
