I'm helping a friend tune a 93 Z28 (LT1) using TunerPro RT and Autoprom. We are using the default ALDL definition (.ADS) file that Craig provides for the 92-93 LT1 ECMs. I notice that there are quite a few paramenters that I can't see (i.e. Park/Neutral flag). Is there a list of available ALDL data parameters along with their byte/bit storage locations so I can customize the ALDL definition file with the specific info that I want to see?

On Moates site there is a file called "ALDL stuff.zip" IIRC
It has allot of definitions in there.
Just find the one that is correct for you and go from there.

Guess I'm just in a helpful mood today

Thanks, that's exactly what I have been looking for.

I'm not new to EFI, but this is my first experience with PROM calibration changes. I've done a lot of searches and reading on various topics, but it's tough sometimes to find specific material.

When looking at all of the flags, constants, & tables in TunerPro, I understand about 70-80% of the items and their effect on the tune of the engine. The other 20-30% is the part I'm struggling with. Like the FAQ sticky says, I'm trying to wade into the pond a little at a time.
