Datalogging is using a laptop with darn near any flavor of windows.  I find that windows XP works best but with a little work you can run with Vista, 7 or even 8 if you can get around that metro mess. you can run Windows 10 and 11 now with latest version of WINALDL and Tunerpro RT

These days, most customers build setups very similar to one of my projects or one of my posted customers projects to avoid a lot of headaches.  However they still happen.  This tool will allow you to record sensor data while you drive the vehicle around and email me that file which I can play back and help you determine what is wrong.  I also typically like to look at a couple spark plug pictures along with that data so that I can make sure the computer is adjusting the fuel correctly.  More than once I have gone through adjusting the programming on the chip just to find out the o2 sensor was bad screwing up that data or that the customer had the wrong spark plugs for the heads they were using.

I have sub menu items for the software and cable to do this datalogging with your OBD1 (prior to 1996) GM vehicle.

First is the software and 2 programs that I recommend and which to use has to do with the OBD1 vehicles ECM/PCM computer type.

The early 160 Baud TBI systems prior to 1993 and some 1993-1995 5spd ECM’s which were 160 Baud, we use a program called WINALDL from Jonas Bylund.  software has been updated so it now runs on the newer Windows.

Since TTS Datamaster is no longer available, most are now going with TUNERPRO RT which has lots of support. Just google it and you will find the download and datalogging definition files as well as LOTS of youtube videos on using it. If you do use it to send me data, export the data to CSV format under the acquisition menu.

Lastly the cable, www.aldlcable.com is who I have been recommending for years and if you have an issue with the cable they have been good to help my customers out.
