Do you get any error messages?
Do you have more than one serial port? The program uses serial port 'COM1' by default. You can edit the file winaldl.ini with notepad. You can select which com port to use in that file.

The software links up with my '88 8063 just fine.. needs a little value tuning, but if a tunable developmental version were released, I could start work on getting the formulas... someone has to hack this ecm someday, and I'm bored enough.. anyway, alot of the values seem to be quite similar to the 8746 values (most of the data seemed quite feasably accurate minus CTS and a couple other things) Great software, loads of potential, and you just can't beat the going price tag. Keep it up, guys =)

The Radio Shack Catalog No. for the 2N2222 transistor is 276-1617. The pin out on the back of the card it wrong according to the Motorola web site. When wired 1=C, 2=B and 3=E my cable works.

Update: WinALDL v1.01a works absolutely fine on the '88 ECU. IAT seems high, but feasable. CTS is right on. TPS reads 11% throttle at closed throttle and, while otherwise accurate, TPS readout is awfully low on detail (hops by about 4 percent, doesn't shift for each change of raw ECU data).

Also, Radio Shack transistor MPS2222A works in place of the 2N2222 (good, since 2N2 isn't available in stores, and MPS is)

Is anyone adding a data logging function to this program?

The IAT uses the same temp calcuation as coolant. That might not be right. I need a conversion table for the IAT to fix that.

I convert TPS voltage (0V - 5V) to percentage(0% - 100%).

At idle the TPS reading should be around 0.5V , about 10% of the 5V range. At WOT you probably won't get much more than 80% or so ( 4.0V ). If someone knows the specification what the TPS voltages should be at idle and WOT I can adjust the percentage scale.

I have been thinking about adding data logging. It would be easy to log the raw data, but that is not very useful. If I log all flag, sensor and errorcode data the log file would get large fast.
It is also a required to be able to turn on / off the logging.

If you have any good ideas please let me know!

You could log the raw data and have an option for the program to read the raw data log and convert it, with ability to read the data one full packet at a time, or at 160 baud for a neat playback option. Would save lots of space on the logfile and it would log all possible functionality.. probably be very good for helping to determine min/max values too.

Btw, TPS min value *should* be .54-.56 volts.. I checked my tps less than 2 weeks ago (since it was fubar and intermittently shorting to a valve cover) and it was where it should be (when it wasn't shorting anyway). WinALDL reports the ecm as sending 29 for the raw tps at closed throttle. I'll check WOT later today. I think we'll need to get a large base of people to test this.

Anyone using the software, grab a multimeter, your laptop, and a friend! Start logging precise volt values for TPS vs. ecm raw data. This program has lots of potential, and I, for one, will be sending you a full breakdown of the TPS data soon.

And yes, I think the IAT needs to be changed.. seems way too hot when "cold air" is 118 degrees while it's about 55 outside.
[NOTE]: 'course.. that could be my thermac's fault.. I'll go see what it says before I even start my engine today.

After staring at a couple other programs, I noticed one allows you to change closed/WOT TPS settings within the config and adjusts the percentage scale accordingly... This may not be a bad idea in case people have slightly different TPS ranges.

I found some info about the TPS sensor for a 1990 TPI Corvette.

With throttle closed: 0.54Volts +-0.8V (0.46V - 0.62V).
WOT: 4.6 Volts

If our cars are the same ( They probably are) then the voltage span is 4.06
Volts.

That would make the percentage range go from -13.3% to 109.9%.


I could add that (0.54V and 4.6V) as default parameters with the possibility to change them in the ini file.

New version 1.01b

* Buggfix Sometimes the INT / BLM / O2 tabs would stop updating when switching from Spark tab. (if high RPM / high MAP)

* Changed the TPS percentage range ( -13.3% to +110% ) to put 0% at 0.54Volts and 100% at 4.60Volts. The range can be changed in the configuration file WINALDL.INI

Spiffy =)

And I was wondering if that was a bug or because I turned my car off before switching around....

Any further final word on this prog's compatability w/ 88' ECMs?

If so I'll have two happy TBI brethen, who I serve as their "tech-department"

How come my connector looks different than the one shown above? Mine is |F|E| |C|B|A|
|G| | | | |M|
I have an 88 TBI, but I didn't know if it should be different or not.

You're fine tyler... all you need is A (ground) and E (data) for the scanner to work. Lemme know on IM how your progress is coming, and happy turkey day man

Ver 1.02b Beta is out now.

http://www.winaldl.webhop.net

* New configuration dialog - no more editing in the INI file.

* New data logging with dialog.

* New configurable TPS percentage range.
* The 1227808 data is updated.
* Buggfix New MAT calulation.

Hmm I dont see any place to connect it to my computer in my car....

All wires and connectors are connected to something... Unless im not looking hard enough.. Are their any connectors that I need to disconnect to get a readout? Thanks...

Very Cool. This has been a great tuning tool, and it was interesting to watch my BLM's go up after I installed a very low-restriction exhaust. Please, Please keep up the great work!

OK, I diconnected the only thing that I could fine with a through like g... I plugged in the ground in a and data in e.. tried to start my car and it wouldn't

I then connected the connector with the data and ground still there... The car start but was rough... turned off the car and then started it again.. everythying started fine but Im not getting a reading from the software.... Im on com1 and I exited the program while it was still conntected... the car went back to idling reallly rough liike it was going to stall.... How come Im not getting a reading?? Could it be the connector.. I made exactly like the others posted... Can anyone help me? Thanks...

ANy chance I could pay one of you guys for this cable?? Right me at mike@mikekey.net with your price.

Could someone post alternative Transitor PN's. I can't find the 2N2222A anywhere. Also, I have a laptop, but it's fairly new so it has no DB9 serial port. the 2 serial ports are USB, and I Believe they're set to COM 1 and COM 3. Is there an adapter anyone knows of? I've done some reading to try and figure out how to make a USB interface, but it seems way out of my electronics scope. Thanks guys.

I don't know if anyone ever tested if the USB to RS232 adapters work with the scanner software.

Where Can I find a Cross reference chart to see what is normal and what is abnormal? I have the data, but now I'm need to figure out what is good and what is bad.

Thanks

Read up on all the values and what them mean over at the www.diy-efi.org website. Go to the GM-ecm site and then I think the next link is "papers by members." Look for Tuning information. A few pointers: Learn about open loop and closed loop, understand that BLM above 128 means fuel is being added because of a lean condition at the o2 sensor. BLM below 128 means the ecm is taking away fuel from the stock VE (fuel) tables. The scan tool isn't useful under WOT because our baud rate is on the slow side. Remember that BLM goes to 128 instantly when you smash the pedal to the floor. It takes time before you fully understand how everything works together and relates but if you search the board you'll find 98% or your answers.

I am interested in this program but I am unsure of my ecu compatibility. I have a 1992 tbi s10 2.8liter v6 .

I am going to see what I can find out about my ecu.

Perhaps the next version can incorporate a small "?" option that would breifly describe data subjects within the software directory itself. Like the "?" option on windows.

Very Impressive Software.

link at the top of this post no longer works? does anyone know the correct link to this tbi software? i checked it out once before but I run a carb and Im thinking of switching to tbi again...and wanted this scan software...came to look for it and I can't find it

Try this one, it just worked for me. http://winaldl.webhop.net/

I'm looking at trying this out and am going to build a cable.

<b>question:</b> The web site for WinALDL has the diagram with a 10 K resistor going from pins A to B on the ALDL connector. The accompaning picture only shows two wires that are plugged into the car. Is the resistor only needed for certain ecms or is it just a typo. I have a 91 RS.

Thanks,
Jess

.

That resistor is used to select the ECM mode. Some ECM's need a 10k resistor to start sending data, but it will also put the ECM in a different mode with high idle. First try without it. If that does not work then add the 10k resistor.

i need a little help.. i did not see any software that would go for a 92tbi.. will that software work.. also will any cable of that type fit or do i have to make one. if i have to make one will anybody be willing to sell me one at a decent price. thanks

I think that the software should work on the 92 TBI.

which one do i dl ver 1.07b? also any responses about the cable?

How often does the 160 baud capture data? I've been thinking about doing this to help me tune my carb (I've still got the 7747 hooked up) and was wondering how many values I'd get in a normal 0-60, 1/8, or 1/4 mile run. Anybody know?

92rsconvertable, download the latest version. ( today it is 1.07b )

Mark305TBI, You get about one sample every second.

Yikes JoBy.. you're just pumping out version after version..
Thanks for everything =)
And a BIG thanks for the logging function =)
