Hello all,

Any one out there got a TunerPro compatable ecu file or a start of one for the $OD ID. The PCM service numbers are 16156930, 16196395, 16197427. A few of the broadcast codes are BPHD, BPUU, BHMY, BJLL, BJYB, BJYM. It is for a 93 - 95 C/K 5.7TBI, 4L60E engine, tranny combo.

Many thanks

I've got one which only has transmission parameters, but you're welcome to it if you want. it works just fine but I'm using the pcm only to control the transmission. pm me and I'll send you a copy.

Steve

89350STRO

Stevie,

Thanks, I would like to get a copy of your $0D ecu file. Which broadcast code are you using?

Youv'e got mail.

Thanks

Stevie

Ok, the .ecu file is on the way. I'm running a '55 chevy with a 350 tpi. I did have a 700r4 tranny but the way it shifted was driving me nuts. When you drove it gently the 1>2 shift (or maybe it was the 2>3, i forget) would about snap your neck, and then when you were on it, it would shift at waay too low rpms. I've read that this is pretty common on the 700's.

I saw a post on here from a guy who was running a 4L60e on a tpi motor by using a 6395 pcm just for the tranny and a 7730 for the tpi. And to give credit where it is due here's his webpage:

http://dtcc.cz28.com/gta

He was super helpful.

So that's what I did and I am totally sold on the 4L60e transmission. It drives perfectly both when ******* around town and when laying the whip to it. I had to adjust the line pressure tables and the shift points to get it where I liked it but thats the same as in ecm's, pull the chip, reprogram, and try it out.

If you want to try something like this, I'd be happy to pass along all the info I have

Stevie

One more detail, I started out with the BJLA broadcast code, it was the one in the pcm I got from the salvage yard. Seems like it was a 94 Astro van.

89350STRO

Steve

Got the ecu file thanks!! That is what I was looking for, now I will continue to add "stuff" to the file.

I plan to use the PCM to control engine and tranny, I hope to uprade from a 1227747 to a 16196395/16197427.

I am using the BJYA hac from craig moates site. Would you recommend another one or is this the one you used?

Thanks again
89350STRO

Stevie

I cant really say what might be better since I'm only using the transmission part of the pcm and I'd bet that all the broadcast codes are pretty much the same on tranny stuff. You will want to raise the line pressures however assuming you have an engine with some performance. Otherwise the transmission will be shifting very gently when you are giving it more power than it is expecting and that is hard on its innards.

Steve,

Could I please have a copy of that ECU ? It ties right in with my current TPI-4L60E project. I think that it will save me some time on my research. I am working on a long term project to add 4L60E control to my 7730 $8D code.

Thanks,
ED

Grumpy

The Heavy Duty application stuff is fairly different in the tranny stuff, at least in the 454/4L8E cals..

Any PCM tranny is alot better then the non PCM controlled stuff, but if anyone's starting from from ground 0, don't rule out the 8E tranny. Yes, it's heavy and consumes more HP, but the gear spacing is just so much nicer, IMO.

Steve, I too would like a copy of what you have. I have been slowly working on an $OD .ecu also and I would like to combine what I have done with fuel and spark with your tranny efforts.

89350STRO

HaulnA$$,

Would you like to share your $0D ecu file that you have at this point? I have received Stevie's tranny stuff as well as a very good start from burb over at Craigs site as well.

I am in the process of combining these two with one that I had started on. I'll be glad to share what I have and between the four of us, stevie, burb, you and me, and anyone else who would like to contribute we should be able to come up with a pretty decent $0D ecu file.

PM me and I'll send you what I have.

Thanks

Craig Moates

Please post any good ECU file developments to www.moates.net/fileman/

89350STRO

I have received three $0D ecu files with lots of good "stuff". I want to thank Stevie, burb from Craig's site, and HaulnA$$, for the files. I am working on combining them all with mine and verifying using the $0D hack.

One thing concerns me; even though the $0D hac says it is from a 16197427 the BCC used is a BWDM, which indicates it is from a 16168625 ($06?? mask). I didn't think the two were interchangeable?

One other thing is in some of the parameters there is indication of using an MD8 which is a 700R4 not an MT1 / M30 4Lx0E. I thought the 16197427 and even the 16168625 were PCM's. . Was the PCM ever used with a non-elect tranny?

Can anyone point me in the right direction in the above two cases??

As soon as I get a decent $0D ecu file I'll post it at Craig's site.

If anyone else wants to help out jump in the waters fine. If you have an ecu file to contribute please PM me. If you have Suggestions/recommendations please just post them here.

If anyone has tunercat with the $0D file and wants to cross check it would be greatly appreciated.

Thanks

I am just wondering if anyone has something ready to go yet. I am too excited that people are working on this one! If I get ahold of this ecu I can dump my extra 350 in my 4x4 Sonoma.

89350STRO

Breazlan,

I have been able to put together a pretty decent ecu with the help of several people, HaulnA$$ is in the process of verifying against the tunercat definition file. As soon as it is complete I will post it at Moates.net

Thanks
89350STRO

Breazlan

iTrader: (1)

Sounds good. If you would please, post a link to it here. I will watch for it here.

89350STRO

The $0D ecu file is ready in it's first version.

It is available at http://moates.net/fileman/

Located in the Binary Editor Definitions section

The file name is 0D_v01.zip

If you have any request, changes, comments or anything else concerning this ecu file please post them here.

This is version 01 of the $0D file dated 04/21/04. Hopefully there will many other versions with more definitions. This ECU file is for the 16168625, 16156930, 16196395, 16197427 PCM's that are using the $0D mask.

There were several contributors that helped with this file, Stevie@thirdgen, burb@moates, and HaulnA$$@thirdgen.

Special Thanks goes to HaulnA$$ for his verification of the file.

Thanks

YES! It must be my birthday!

Much thanks to those who put this together.

Stevie

This thread has been dead for a while, BUT...Will a 6395/7427 pcm run a tpi system?? I've been looking at the $0d hac and wiring diagrams for a while and I cant see any reason why not. This would definitely clean up my installation where a 6395 pcm controls the 4l60e transmission and a 7727 ecm controls the engine.

HaulnA$$

Yes it will. Edelbrock sells a TBI to MPFI conversion kit based on this PCM for thr TBI trucks. The system works as a 2 bank fire setup with 4 injectors firing at a time. The two p/h drivers will drive 4 injectors each without putting the circuits into hold mode as the 4 low impedance injectors do not draw enough current to trip the peak to hold current threshold. I am planning on doing a similar conversion myself, but that is at a ways away. Too many other projects going on now.

Stevie

Excellent! I think I've found next winter's project. I would think this would be a popular conversion cause the 700r4 is pretty much a pos in my opinion.

BMmonteSS

That ecu file is absolutley brilliant. What are you guys using for a scanner? Doesn't this thing have the faster baud rate? Man I'm excited. The local tranny shop says he has converted older 700-r4's over to electronic control with a special drill bit and a new valve body. He told me this a while ago so I'm gonna go find out if it is possible to convert. This is the perfect setup to use to transfer from tbi to MPI without starting over from scratch.

I use Datamaster for scanning/logging. It works really well. I'm gonna try TunerProRT and see if I can get it to work. Maybe this weekend. These PCM's do run at 8192 baud, that is what makes them attractive to converting to an MPFI setup. Good luck with the tranny mods.

Stevie

TunerProRT does scan this pcm just fine. I had to write my own aldl definition but since im only using the tranny control I just look at a few items.

Steve

HaulnA$$

I'm sure I can get TunerProRT to work fine as a stand alone setup, but I am also using the USB version of the AutoProm to emulate simultaneously which makes it a little more challenging and I heard there may be some problems getting the USB AutoProm to work like this. I think it was wilth 160 baud systems where the difficulty was, but I'm not sure. I guess I'll find out.

Mangus

Using TunerPro RT and your USB AutoProm, you should have no issues simulataneously datalogging and emulating, regardless of whether or not its 160 or 8192 baud datalogging.

If you do experience issues, let me know so I can get it worked out! (TunerPro is, afterall, a very large experiment =)

Craig Moates

Do folks have everything they need to do TunerPro/AutoProm/log stuff with the $0D now? If not let me know. I'm going to do some housecleaning and wanted to nail this down...

Stevie

Craig,

I've been leisurely working up an ALDL definition file for TunerProRT for the $0D. But if you or someone already have cranked it out I'd like a copy. It would save me the work, and I'm basically lazy.....

Steve

89350STRO

I have a copy of one I received from burb over at Craigs site. I have not used or confirmed this file. I'll be glad to send it to ya just PM me with your email. I think HaulnA$$ is working on one as well.

I have been working on some updates to the $0D ecu file, and will post them soon. Does anyone have any request/suggestions.

I haven't converted my 1227747 system still rebuilding the 4L60E, trying to make it as bullett proof as possible. I think I can just repin and add the tranny harness!!??

Thanks
89350STRO

Grumpy

Is there a way to force folks to have to read a disclaimer, or .txt file about a .bin?.

If anyone wants to read thru my truck cal, Mask 85, it has a pretty nice tranny recal, just email me.. granted for the 4L8E, but might serve as a model for what to look at. The Tune is for a heavy truck, with heavy trailer, 87 Octane.

Stevie

You bet, I'll take a copy of whatever you have for an ALDL definition file. I'm at:

flapsupcleanup@att.net

On your conversion, yes that should work I think. However, you may have some issues on getting your speedo/cruise to work. I'm not sure what you have right now, but of course the 4l60e doesnt have provision for mechanical speedometer. Are you planning to use a DRAC module between the vss and the pcm? If so, it has different outputs than a normal vss but can still work. I've got lots of info on that since I've been doing the same thing on 2 different cars. If you need anything let me know.

Steve

89350STRO

The Van is electronic speedo, and is currently using a Buffer I think. I havn't dug into the dash to determine for sure but the wiring diagram manual indicates a buffer, but I plan on using a DRAC. I have several, and will modify one to an adjustable unit. The ads file is on the way.

89350STRO

BMmonteSS

Not to start any trouble but I just noticed our good buddy over at GMPCM just came out with a new OD pcm file. Wounder where that came from?

Craig Moates

The $0D definition, just like all other definitions, is merely a roadmap to existing General Motors firmware. The factory chips are readable, the hardware platform is well-known, and it's just a matter of time looking through the 6811 code to deduce what it all means. That is hacking.

Of course, most of the definition files are created from existing source code disassemblies/hacks. I'd be surprised if those that have been referenced are any different.

I thought this might be a good place to ask this since this is what I am working with.
What should I be modifing in the BIN to make the engine run right when not using the egr valve?
And, what do I change in the BIN if I decide to make an injector change.
Thanks

Mangus

Oops. posted in the wrong thread.

Breazlan

iTrader: (1)

?? oops ??

BMmonteSS

This isn't the best place to post but.......Just set the egr enable constant really high, that way the egr won't ever "come on" in the ecm. If you have more questions you might want to try the function. That exact question has been asked alot.

Breazlan

iTrader: (1)

Reading the boards is kind of why I asked here about it. I once saw on here something about some tables that assume the egr to be active and when it is not it messes up the way it runs. That may not be true but I just remember seeing it somewhere.

Also, if you take a bone stock vehicle, change the injectors to different capacity injectors, do you need to do other stuff than just changing the injector constant? Do you need to then take readings and work with the tables?

Grumpy

Yes, er, no, well, maybe.
It depends, going from say 22s to 24 may not take much if any work.
Going from 22s to 60s will.

And it all depends on what you call satisfactory. For some if it starts and runs as well as a stock cal, that's more then good enough. If you consider the stock cals, as just barely drivible, then you'll be doing alot of work.

To disable EGR in the $0D mask, disable the "Error 32, EGR Fail" bit at L5B02, bit 6, set to 0. Disable all of the other EGR qualifiers like Coolant Temp min., TPS window, MAP window, RPM window, etc. starting at L46EF - L46FE. Zero out the "EGR Spark Correction vs RPM vs Vacuum" table at L4859, lastly disable the "Desired EGR vs RPM vs Load (vac or map)" table at either L4704 or L4783 depending on the type of EGR valve you have. This will totally disable all EGR function (provided you remove the EGR valve) in the .bin but be prepared to adjust the main timing table as the higher combustion chamber temps will cause knock in some areas even if they were tweaked before. I noticed my truck ran better after EGR delete.

Breazlan

iTrader: (1)

Thanks, I am pretty sure I don't need to worry about the egr now.

I have a question about the fuel tables. I am just trying to tune light throttle now. To start with, I need to work with "near idle" and "off idle" from what I can tell. They overlap so I wanted to be sure I understand when which is being used during the overlap. My "max speed for idle fuel table" is set at 3 mph and "max %TPS for idle fuel" is set at 2.75%. If my vehicle is over any of these two values then it is using the off idle table? Is there something else I am missing?

Also, where are the cut offs for switching to a different cell in the tables. Ex. - Does the 1600 rpm, 40 kpa cell cover rpms 1600 to 1900 and kpa 40-49.9 or does it cover something like 1400 to 1799 and 37.5-44.9 kpa? Please don't tell me it can very too! I would believe it if you said so because of my scans so far.

The qualifiers for off idle fuel in this case are as follows: 1) over 3MPH, OR TPS > 2.75%, OR RPM > 1800. Any one of the three conditions will put you in the off idle fuel table.

Your second statement is closer to the truth and it does vary in that the cell boundaries are not absolute but have hysteresis. I'll explain. I'm not sure of the exact values (I could'nt find them in a quick search of the hack) but they are something like 3 Kpa and 75 RPM. Here's how it works, I'll use your values as an example. Say you are cruising at 1800 RPM and 48 Kpa and accellerate to 1910 RPM at the same Kpa. You will still be in the same table cell until you cross over the hysteresis point of 1975 RPM. Now say you accellerate to 2000 RPM at the same Kpa, you have now crossed into the next cell and will stay there even if you decellerate to 1825 RPM. The hysteresis values are there to keep you from teetering over cell boundaries. The same principle applies to the Kpa values and this strategy is pretty much applied to all tables. HTH

Breazlan

iTrader: (1)

ooh no
I trust you are explaining this, but I am not understanding it yet. I do greatly appreciate this though. Maybe I should skip this for now.

I see you have used datamaster too. Would you mind explaining what I am looking at and compare it to the tables.

1) When I read a blm, how do I know what cell in the table it is refering to. I believe this hysteresis stuff is playing in on my not knowing where I am on the table. I think I know where a blm goes but later on in a scan I get a whole different number in what I believe to be the same location.

2)Fuel Trim Cell - is that usable info to help me with the tables?

3)Xcounts - am I trying to achieve a certain number here. What is it telling me.

4)Just curious - when in park, do you also get the active gear as D1?


With the overlap, I never idle over 1000 when parked. So the "near idle" table is not used beyond that. yes?

Breazlan

iTrader: (1)

Hold it, I got it! In your example, you are going by increments of 2000 rpms. I was thinking 4000 like the 'off idle.' You are saying 1900 would be the cut but you have to hit 1975 to jump from 1800 to 2000 cell and back down them to 1825 to go back into 1800 cell.

Cell to cell cuts are half way between plus the hysteresis factor. Correct me if I am wrong.

3 kpa and 75 rpm is usually what these numbers are? Is that 3 kpa for the cells that are spaced 10 kpa apart? That makes sense but not for those spaced 5 kpa apart.

HaulnA$$

O.K., I found the numbers in the hack and they are 2 Kpa and 75 RPM. Let me try to explain this hysteresis and cell thing again, I had a touch of dain bramage. On the off idle fuel table, the 1600 RPM 50 Kpa cell would theoretically cover from 1201 RPM up to 1600 RPM and from 40.1 Kpa up to 50 Kpa without hysteresis. In the real world to keep from teetering over cell boundaries the 2 Kpa and 75 RPM hysteresis values are used. So when accellerating at a constant 45 Kpa (theoretically) from 1500 RPM, you would have to reach 1675 RPM to cross over into the 2000 RPM cell and decellerate to 1525 RPM to cross back into the 1600 RPM cell. The same applies to the 2 Kpa value. 52 Kpa to cross into the 60 Kpa cell and 48 Kpa to cross back into the 50 Kpa cell. Does this make sense? Since you are using Datamaster, you can call up the histogram function to see what cell you are in fairly accurately. I'll try to answer some of your other questions.

I use the histogram function. It is fairly accurate off idle.

2)Fuel Trim Cell - is that usable info to help me with the tables?

Yes and no. A fuel trim cell, aka BLM cell covers many cells in the fuel table as defined by the BLM cell boundaries in your .bin.

Quote:

3)Xcounts - am I trying to achieve a certain number here. What is it telling me.

Xcounts are the number of times the O2 sensor voltage crosses over a set value when going from rich to lean and lean to rich. The prescense of Xcounts tells you that the BLM's are controlling fuel trim in closed loop mode. There is no certain number to shoot for, the mere prescense of Xcounts in closed loop tells you all is working.

4)Just curious - when in park, do you also get the active gear as D1?

Yes, but the Park/Neut flag is set.

Quote:

I'm not sure what you are asking but look at my previous post for Idle fuel qualifiers.

Ok, I will look at this all over again then, no problem. This is probably why I have not been too fond of the histogram so far. Didn't match up well with what I was thinking.
