Hello All-
Just starting this data logging journey...
I have a 1992 K3500 7.4L 4L80E Dually.
I have purchased the 12 pin ALDL to usb cable and downloaded tunerpro rt....
Now I need the correct files to load into tunerpro......and how to get started......
Logging data from the truck to debug open loop @ idle issue is my primary goal..
I have attached the ECM service label..
Any and all help to get started is appreciated.

It looks like this pcm can be a pain for datalogging. There's an old thread with a few different ADX files that may or may not work. There's some discussion in this thread about logging and some discussion about tuning if you end up going that route. http://www.gearhead-efi.com/Fuel-Inj...erceeded-to-D8
One working file can be found here: http://www.gearhead-efi.com/Fuel-Inj...5&d=1337826699
There are notes that you may have to edit connections in the .adx and Eaglemark felt it was important to have the engine running when connected. If you are having trouble getting the adx to connect speak up and someone should be able to help.
