About

WinALDL is software to datalog on GM vehicles that use the old 160 baud rate.  This includes but is not limited to vehicles using a 1227747 and 1227165 ECM.  Most older TBI GM computers will speak this protocol.  WinALDL does NOT speak to newer GM OBD1 vehicles that use 8192 baud communication.

WinALDL is available from http://winaldl.joby.se/

WinALDL was written several years ago.  It will work best on Windows XP or older operating systems, if available.  You may need to use a VM or Windows XP compatibility mode on newer Windows7 systems in order for it to run 100% properly.

WinALDL will work with both our ALDU1 and AutoProm.

Setup

There are a few setup tasks that need to be performed.

• Ensure that your ALDU1 or AutoProm is assigned a COM port between 1 and 4.  Make sure you choose a port that does not conflict with system resources.  (see USB guide)
• If you are using the AutoProm, ensure that it is set to pass-through *NOT* AutoProm mode. (see AutoProm troubleshooting guide)
• On most 160 baud applications, you will need to set the switch to 10k mode on your AutoProm or ALDU1
• Set the COM port selection in WinALDL to match what it set up to on the USB driver under the control panel.
• Set the baud rate to 4800 within the WinALDL program.
• Select the ECM type in WinALDL which matches your ECM.
• Make sure the ALDU1 is connected to the laptop prior to starting the software.
• Turn your key off, connect the ALDU1 to the car, and start the software.
• Turn the car on, it should connect.
