To answer your question about the program there are very few scanners that will do both as Mark said. If you are just wanting to be able to do obd1 vehicles or your vehicle more specifically its hard to beat the data that datamaster can provide. http://www.ttspowersystems.com/DataM...ownloads2.html

Just find your vehicle and give it a try before you buy it.

If you arent wanting to be tied down to just that vehicle then efi live v4 is another option although I have never used it and can not speak for it. http://www.efilive.com/index.php?opt...=48&Itemid=133

You can use the cable listed above with either.

I am sure there are others floating around but those are just two I know of.
