I have the USB WINALDL cable and the newest version of WINALDL software. When I connect to the car I only receive data on the RAW data panel. I have numbers for MW2, PROMIDA, PROMIDB, and an occasional number for IAC and CT. Nothing else shows up. No other screen shows any data.
I have the 1226870 ECM selected.

Am I doing something wrong? Is my ECM bad?

SBNova

Are you using the 10k resistor? On my 85 with the 6870 I had to use the resistor full time to get data, otherwise I only got a few fields.

DarthD

Yes, I am using the resistor. Without it the top rows fill with numbers but they do not change.
With the resistor, the numbers do update.

since were on the subject....SAME boat here too-almost. With my winaldl program running (While connected to my 85's ecm) I get the raw data,sensor data and errorcodes showing, but as for BLM, 02 and INT--these 3 are exactly the same, shows a bargraph and a bar floating between 800-1200 scale----I'm assuming thats the RPM of the car as its running. I thought the bar graphs would show the data right there before me, But I have discovered by hitting the
"save" button at the bottem, it will save the file onto the aldl program. And when you click on that, you'll get several bar graphs show up and the bottem ones have "1" in every section...Any idea of how to get the proper readings, pcm4less needs the BLM/02/INT readings inorder to properly check the readings and make sure the chip is correct that he did for me.

Here is 1 same off of an o2 file: Not sure what 24/48/72/96 etc are ?? baud rate, I know the left column is the RPM range,

Nevermind. I find help at thirdgen.org. I needed to change the baud rate to 4800. Now all the data shows up.

chillcat

Hey, does your data show up under blm int and o2 ?

DarthD

I have data under the BLM tab but it is slow and takes a while to show up. So far I see nothing under INT or O2. A box will light up just like the BLM but no data shows up.

chillcat

so data will start accumulating in the BLM graph? Mine doesn't, instead it has a lit up box showing 800-1200 and moves back/forth.

Why not just try TunerPro? Its much newer and better than WinALDL. There never used to be a publicly available XDF for a 6870 but I think there is one posted on Moates.net/fileman now. A 6870 is $1F right?

http://www.moates.net/fileman/index....neral%20Motors

I think you'll also need the datastream definition here;

I wanted to try other software but could not find the XDF file. Now I can. Thank you!

Will TunerPro work with the .ads file here? The only 870 ECM file I see is: 1226870_160baud_85_Fcar.ads which appears to be for the LB9 (305ci TPI). Will this work, or ??

Thanks,

Gary

SBNova

I never tried it because my 6870 ecm is long gone. The 6870 was used in a few different cars in '85, and although the bin file changed the ecm is still the same so it should work fine. Newer 165 bins are easily interchanged between F and Y cars.

chillcat

I downloaded that tunerpro file, so when I connect the aldl chord to laptop, I open the tunerpro log and fire up engine and will data start showing up in the bargraph? I'm not familar with tunerpro. Car is at chevy getting a problem fixed so I can't check it yet.

SBNova

You'll actually need TunerPro RT. It costs $35 to register it, but its free to use eternally if you dont mind the 10 second nag screen. You *should* load the correct XDF file for the 6870, which really only shows what you can change in the bin file, if you have the means to read or burn a chip (or emulate). Then click the small icon near the top that looks like a hand holding a piece of paper. Under datastream definition there is a box that says "browse". Click that box, and select the 6870 .ADS file from wherever you stored it. While your on that page, click the "select log file for REC/PLAY" button, and create a file to store your datalog. Logging/recording is not required to view data, but this is where you create and name the file to do so. Choose a name and click "open". It will say the file doesnt exist and ask you if you want to create it- click "yes". You are now ready to record data. I usually name my files with the date. Create a new file each time you log.

Once the cable is hooked up to the ALDL port and your laptop, turn the key on (some just start the car, but I like to log the startup myself). Click the two opposing arrows- thats the connect button. It will say "connecting" or "connected" at the bottom. Once connected, you can click the letters near the top of the screen "D" "V" "F" or "M", those are different ways to view data. When in "D" or "M", you can right click any field and change it to view whatever you want, like TPS,RPM,engine temp, etc...

To record, just hit the red dot, and to stop hit the stop button. Then disconnect communication and hit play to replay the data.

When I connect the USB/ALDL cable, I get the following on the MW2 line on the raw data page, I get 255 over and over. When I turn the key on, everything stops, starting the engine also stops the 255 from showing up. Nothing else shows up anywhere in the program. Please offer some suggetions !!

Slinky85

do you have the right ECM definition selected? idk if WinALDL has a specific ECM # for 1990, It could, I never checked, go to configuration tab to switch , I think you need to run 4800 Baud also, 2400 is default. also make sure you are in the right com port...

rons85

I'm using that .ads file with Tunerpro on my '85. Does work OK, with a couple of problems. A few of the data fields are looking at the wrong places in the datastream, you will have to edit the datastream definition (simple to do) to fix it.

I use the Moates cable setup with the 10K resistor switched on, works fine.

I have the same problem as you with WinALDL - only data on the RAW tab. This is With that same Moates cable setup and With the resistor on. Yes, I had to select 4800 baud to even get That much. The good news it that at least all of the sensor data appears to be correct and accurate. I wish it would show the BLM's in a table, though I guess I'm not certain that the -6870 ECM even Has that sort of organization.
