WinALDL - 160 baud ALDL reader

WinALDL is a program that reads the ALDL data from some supported ECM types. The data is presented in a way that will help when tuning a car after engine modifications. A simple hardware interface must be built to convert the ALDL data stream and make it compatible with a PC serial port

The original idea for this program came from Ken Kelly. At first we just wanted to write a good free scanner for the 1227747 ECM. Then We added another one ... and another ...

I have used information found on the internet when writing this software. I don't have access to the ECM's supported, so I can not test everything. Please let me know if you find something wrong and I will try to fix it. If you have a 160 baud ECM that is not supported you can still use the raw data logging. I might be able to add support for more ECM's, but I need information about the 160 baud data stream for that ECM.


If you feel like saying thank you for the software and wish to donate a buck, you can use the PayPal button to the left. Otherwise, ignore the button and use the software anyway.
