Hi guys, my friend has a 92 Cadillac deville with the POS GM 4.9 V8. I saw on diy-efi a zip file with .ds files for just about any application. What program do I use to interpret the .ds file to allow me to datalog a specific application? It's tough to search for a topic like this since ".ds" is not long enough for a search string. We may eventually convert his car to run an F body ECM so we can burn chips for it. It's probably not worth the effort since this thing is even smaller than a 305 and in a heavy tank car, but that doesn't mean we won't try.
