I need some help please. I'm making changes to my ECM and i'd like to stay in the BLM 128 range. My problem is what tool can enable me to log my BLM? Is this something that tunercat or pocket programmer can log. OR is there a tool that i have to go out and buy for that?

what i'm thinking is that the chip stores the blm data (logged data). I'm thinking that i should be able to open it in a program after pulling the data off the chip. is this true?

thanks in advance

 

You need a scantool or scanning software. There's plenty out there. Moates' ECM, TunerPro RT, WinALDL are freeware/shareware.
Diacom, TTS Datamaster, TurboLink are commercial.

 

I am using TunerPro and DataMaster. If you set up a spreadsheet, you can systemically track changes and keep a chronological record. DataMaster's Histogram is a cool feature that gives you a visual record of lean and rich cells at different points. It's not perfect by any stretch of the imagination, but is works good.

You can see my complete description of how I did it here

As far as I understand the process, no the chip does not store the data. That is why you need an ALDL cable with serial port plug (or USB adapter) and a program like TunerPro or DataMaster.

Good luck datalogging, Ed

 

Oh I see so it sounds like I have to monitor data live and on like a obd1 cable and use a program to capture the data. Man guess i gotta send more of that money. Does anyone know about how much it is buy one of these cables and the software?

thanks again

 

HARDWARE:
You can get a ALDL cable to serial port, but I opted for a USB connection. So I bought the following from www.moates.net

CABL1 OBD1-Style ALDL Connector ($30.00)

ALDU1 USB-to-ALDL Converter ($50.00) - but also includes a USB cable from converter to laptop.

SOFTWARE:
TunerPro RT (free, but $30 to register)

DataMaster: You can download it and get 20 free uses, then you have to purchase a key.

Good luck, Ed

 

So has anyone build a OBD1 cable for logging. I have all the cables and serial port adaptors. i just need the layout ( which wires go where) then i should be able to use from what i hear is a program called WinALDL to stream data down to my laptop while driving? anyone have any info about this? Sorry i'm the kind of person if i think i can try to do it or build it i really try too. as i'm sure most of you out there are too.

thanks

 

If I'm not mistaken, I think Craig provides directions on how to do it... www.moates.net

 

You haven't mentioned what ECM you're using. That makes a difference as to which scantool is most appropriate.

TBI and 160-baud stuff, WinALDL is good.

'165 and '730 ECMs, Moates ECM program works really well. I probably use ECM 8.52 more often than anything else.

TunerPro RT can be configured for about anything. You can use it for awhile to get the feel of it without registering it, although I'd strongly encourage you to register it if you decide to use it. It's a great program, and worthy of our support.

Datamaster is pretty good with the '730 ECM ($8D code), and has some nice features, but if funds are tight just stick with Moates or TunerPro. There is a different version for $32B ('88 MAF). I don't recall there being a $6E ('89 MAF) or TBI version available. I use DM only rarely.

Cables, there are two common designs, the "2-transistor" and the "MAX-232". Doing a search should net you those. I think the WinALDL site has a schematic for the 2-transistor. You can build one pretty easily. Andrew Mattei's site has info on the MAX-232.

http://www.akmcables.com/

Note that a lot of the cost of the cable is for the ALDL plug adapter itself -- there's nothing that says you really need to have a fancy molded ALDL plug, esepcially if you're only tuning on one car. With a little splicing and soldering, you can use whatever type of connector you like.

Making your own saves quite a bit of money. I think AKM will sell you a complete parts kit for like $35, or just the printed circuit board for $10 or so, so IMHO there's no reason you need to cough up $100 for a fully assembled cable.

 

Well my ECM is a 27C256 when i open it is tuner cat is 32_B. What program should use for that? Tuner Pro or DataMaster? I trying to build my own ALDL cable I have all the equipment but just not the skills to understand a schmatic yet. So i'll be hitting up the ol radio shack later today for some tips. I have schmatic table you'll might be able to give me some tips. it sould be attched here.

thanks

 

Your getting a little mixed up, which is OK.
The number you listed is the actual "chip" not the ECM.
There "should" have been a paper sticker across the top of the controller with a part number on it such as 1227730, or ending with 165.
This will let us know what type of setup you have weather it it a "speed Density" 7730 (works from the MAP sensor on pressure) or a 165 that operates from a MAF that uses air flow.
there are diffesernt variations of both.
You need to figure out which one you have.

You'll need to do some reading up on the different things to get started.
https://www.thirdgen.org/newdesign/tech/promintro.shtml
is a good place to start.
Don't read the Prom stuff YET.
Skip down to the section "Scan Tools and Wide Band Oxygen Sensors"
Then check out this site to get a handle on what setup you may have.
http://www.cruzers.com/~ludis/
Look in the P4 cross reference to determine the "BCC" or broadcast code that you have. Will be a 4 letter combination like AUJP, ANHT or so.
This code will tell you what "Mask" the program is and then you'll know what communication setup is required to communicate with the ECM. ($8D, $32 etc)
It's not as much as it seems to do.
From there, many people can help you because they will know the setup you are running.


ps.
Filling in your info on the profile helps too.

 

Wow great I'll check out those sites ASAP, I checked out my chip and it has
On chip it's self
16069300
27C256/5DBB
5012AP
07270015X
ABTS4767
On box Service number 01227165

What program should work with that? Tommorw i'll be going to radio shack for some help building my cable can't wait till its done. Thanks everyone for all your help this is a great site to learn from.

 

Look for the four letter code written on the MEMCAL cover (usually blue) or in the window of the cover. The first example is from my 91' GTA TPI (in the window you can see the letters ANJF), and the second from my 94' Suburban TBI (it is written on the cover itself - BJLH).




Whatever broadcast code you have on your MEMCAL will determine the mask and the ECU file you need to use to read and make changes.

Ed.

 

Damn man you'll are too cool thanks for the pictures. Mine only has it on the chip is says ABTS. Do you guys know what program will fit my needs?


thanks

 

Lets get some more info to narrow the field.
What year?
What car?
What motor?
TPI, TBI, ??
Does car have a MAF? (mass air sensor)
Auto trans or manual?

There are just toooooooo many things it could be without knowing what you have.

 

It's a MAF setup running a 1227165 ECM with an '88 Corvette bin. Bin is for a 5.7l, automatic trans, federal emissions, and a 2.59 rear. Should be the 32B mask.

RBob.

 

Cool thanks alot everyone for all your help. I keep my eyes open for a mask 32B when downloading the software. I just got all my stuff from radio shack to build a cable so hopefully tonight i'll be able to down stream data to my laptop.

thanks

 

Well I FAILED like a champ. I went out bought all my wiring connectors resistors diodes and transistors. Wired her all up install Winadla freescan and TunerRT. I tried logging data but noting happend. rebooted laptop and all. I ran the car and everything too. Is there a way that i test the com port to see if i get a connection like through hyper terminal or something? I have a pretty good feeling that my cableing is correct because i had a senoir electrion help me from radio shack. are there any sets i can take to figure out what i have done wrong?

thanks all

 

Dude, you should have just bought a Moetes cable and been done with it. He writes his own driver for communication as well.

I guess an idea would be to download his driver and see if that works. www.moates.com Don't be afraid to email him, he is a cool guy.

As for TunerPro, you have to make sure your com port settins are correct within TunerPro, somewhere in a drop down menu. Then make sure your O/S com port settings are the same. On the Moetes site their is directions for an install. I would follow those for starters.

Craig Moetes also sent me a web address for a ALDL cable test. It tests your cable to see if it is working. I don't remember what the site was. My problem turned out to be an incorrect com port setting in TunerPro.

So in a nut shell. I think you have a com port problem or a driver problem.

 

I'm thinking you did not load an "ADS" communication definition file when running TunerPro.

I found one that "might" work on the http://www.Moates.NET site, (Jack' that link brings bunches of popups )
http://www.moates.net/fileman/index....%20Definitions

Try the 12277165_160 baud .ads file.

I use a different setup so I'm not much more help than this.
Unless someone else knows where a "good" $32B ads file is.

While your there go "up" in the directory structure and look under the BIN files and "ECU" definitions to see if one for your car already is there.

 

Good new I think. I install that 12277165_160 baud .ads file. this seems to get me to connected. I looked at my com port setting in windows with the home made cable i created. With the cable connected and car running i was able to have windows tell me the com port was in use. then i opened tuner pro and looked at com port settings it seemed to be connected. so for a test i unpluged the cable(home made aldl cable) at clicked on connect and nothing connected which is normal. Then i plugged it back in a clicked connect and it connected which is great I hope. Anyway i think my cable is working properly After being connected i ran a monitor and it started to monitor but I have nothing but errors. So i might need that driver from craig moats to work with the software. See but i all so tried winaldl and freescan and those seems to be the same deal.... ummm maybe i should just buy a cable. Guess i'll try getting that driver or i might be able to look at anthoer wiring setup before buying one.

thanks

 

Hi all,
Last night i downloaded the datamaster (http://www.ttspowersystems.com/) program along with the cable test program and ran them both. The datamaster cable test passed both tests passed in fact. I got an error when i started monitoring the pcm. error said: Cable is working fine no pcm connected check if the program is correct for your pcm( i did download the 86-88 corvette program) or check your cable for a connection to the PCM? Any thoughts so i did past that cable test from what the program says. plus my com port and my pcm have not gone up i smoke yet, so something seems right.

thanks

 

I believe the TTS check program checks the connection to thier hardware cable only.
That's why you saw the error.
Keep trying with TunerPro. Many people use it. Locate the files, check your settings again and again to be sure they are correct.
I have heard that some of the 160 baud communication setups take a bunch of times hitting connect untill they begin working.
Do some searching on the boards, there are many threads on this. The 160 baud rate stuff if kinda quirky from what I've read.
I think there is something to do with putting a 10K resistance across the A & B terminals to put the ECM into the right mode to begin communicating, then remove it to continue.
Like i said before, I have a different setup so I'm not much help with your particular one.
Keep trying!

If I stated anything too incorrect, someone plese chime in

 

.

 

Cool I'll read up more soon again. Although i did not use a 10k R between the A and B terminal. The only thing i connected was in the A terminal and the E Terminal with my cable. Should i connect my cable and the 10k R at A and B? How can i tell if it runs at 160 baud?

thanks

 

Anybody?

 

So anybody in the hizzel, guess everyone is out drinkin that goood ol Green Beer. I'll be doing that pretty soon too. hey i tried doing more searching but not really any luck i think its time to put this post to rest, I'm just gonna just buy a cable. It's been really fun trying to build this cable though. Thanks for all the help y'all

 

I'm hopeful I'll be luckier with v4.0 of TunerProRT. I had worse luck than you with my experience.

 

Don't give up yet! You have to use the 10k resistor between A and B to get your 165 ecm to broadcast data. With moates' software your supposed to be able to unconnect the resistor after you link up, but with the 165 ecm's I've played with you have to leave this resistor plugged in. It causes the idle to raise and may change a few other things. I'm sure others can tell you more about this.

 

this a pretty helpful post

 

Oh ok i'll try that so I'll pull in my normal connectors E and A terminals then i'll put the resistor between A and B. Cool Ok i'll try that this weekend. Thanks again

 

Quick question for you 8UpAFord-

How did you put together your homemade cable? I'm planning on making one, rather than shelling out the cash to buy a fancy one with the ALDL connector.

Thanks,
Bob B.

 

Sure yeah i hit up radio shack for most items. I'll post it as an attachemnet. Easy to build but damn i'm not sure why it's not working. gets old i gave up after a total of 3 hours or so.

 

I've been there also, stay cool.
A 1227165 ECM in a 1988 vette...I would have thought that the BAUD rate was 8192 and not 160 and data was from A (Gnd)& M (data)???

My 88 IROC LB9 using ECM12327165, ACXS chip and $32b mask connects using a 10k resistor (soldered inside a AKM RS232 interface box) across A & B at 8192 baud. My data connection is to the ALDL pug A & M.
I have connected using EFIlive, DataMaster 32+32 and Tunerpro RT (6E). I also installed a new parallel connector as my ALDL socket was a bit sad. The new socket also provided 12vdc from car to power the interface box. Connection in my case was not immediate it takes about 30 secs or so before the ECM responds I keep sending a connect command from the software and watch the TPS volts.
But then maybe your 88 vette is different?

 

Well the thing is I'm not really sure what buad i'm running. I've given my computer spec in the above posts about my car. I do know that i do not have a M on my aldl. So i have to use E. When using the Tuner Pro software it does say connected but maybe i'm missing somthing or not configuring the software correctly. I might try again

Thanks

 

8UpAFord...160 Baud.

Yes, 160 baud at ALDL E is correct.
I seached around about this as I am also a bit confused to say the least. BUT, as I understand the situation, the E pin is 160 Baud and is the primary data output (this will vary from one ECM to another)...it is present at all times and does not require a software trigger or resistor. 8192 Baud is found (when present) on M pin and rerquires either a 10k resistor across A-B to trigger althrough in some cases a software trigger will also do it.
Now bear in mind that assuming the laptop and cable are correct for 160 baud transfer....the software you are using must also comply with 160 baud data. The Moats ADLU1 seems correct for both 160 and 8192 data using Datamaster and Tunerpro but not for Winadl. I have seen at this link a serial port design that also appears to do both 160 and 8192.
www.techedge.com.au/vehicle/aldl8192/8192hw.htm

I unable to read your schematic file, still trying.

Yeah OK, renamed file to bmp....looks OK....but I've read that you should not use the 10k mode resistor on A-B with TPI systems...use only on some carb systems. See link; www.winadl.joby.se/aldlcable.htm

 

Siggy,
Great thanks so i'm at 160 baud. i'll try the moats software, I think thats really the only thing i have not tried yet. Thanks for all your help i'll download it and check it out

 

Siggy,
I can't find the ADLU1 software on moates site? Can you give me a direct link?

thanks

 

ADLU1 is a interface box for USB connection and transfers both 8192 and 160 baud.
Link
http://www.moates.net/index.php?cPath=24

HOWEVER, the more I look at the 160 baud issue the harder it becomes...Moates ADLU1 box transfers 8192 and 160 but I.m not sure that all software can take it from the USB port...? I read in the DataMaster manual that it would not take 160 from USB..? A Email to Moates could clarify the issue.
It would seem that you need to look carefully at matching your choice of software and interface using 160 baud, which of course is the only choice you have...maybe one reason why people change ECM's? Looking at the WinALDL site http://winaldl.joby.se/aldldata.htm
indicates that at least WinALDL (software) supports 160 with a recommened cable arrangement.
The link http://www.techedge.com.au/vehicle/aldl8192/8192hw.htm also has very good info for your situation.
Confusion? me too, sure glad my Camaro gives me 8192 baud. I think that unless you can clarify the use of USB at 160 baud you may be better using the serial port.

 

well thank you very much for all your help. I'm thinking looking at the schmatic gives me a head ache, so i'll just probaby contact moates later. I mean don't really think my BLMs are way off. I did a few minor tweeks nothing crazy. So i'll wait till i get more cash in my pocket and get that setup. For know i'm going to probaby save my money for exhaust from full front to back and port out my intake then go from there.

thanks for all your help
