I can access the override codes (P0.1 - P1.7) through the Climate Control Panel. This is great but would like to display it better.
So what I want to do is hook up an OBD1 ALDL Cable to the car and display the information on a laptop, with guages and dials.
I have looked around quite a bit and am not sure which software supports my ECM.
Anybody using software on this era of vehicle?

I believe TunerProRT not TunerPro will do what you want. They list a configuration file for the Deville and will allow both data logging and real time display via a Dashboard Display.

The last time I tried a scan tool with an 88 deville it didn't work even tho it was supposed to be compatible. With OBD1 you are limited with what it can do.
