    I'm new to the world of computer controls and tbi. I have picked up on the fact that ALDL is a great diagnostic tool but I am not clear what exactly it is. Is it a scan tool? If so, is it affordable for someone that doesn't wrench for a living?

    I guess you could call it affordable, it's a shareware program you can download for free. /forums/images/graemlins/grin.gif If your are handy with a soldering iron, you can make the interface cable for a little bit of nothing. If not, you can order one online or have a bud make one for ya. One thing though, you DO need a computer to use it. I don't have a laptop, so I drug an lod computer that I had layig around out to the garage and am using it.

    Assembly Line Diagnostics Link /forums/images/graemlins/thumb.gif

    It is found lower left of the steering column right underneath the dash. This is where you can hook into the computer with a diagnostic tool, or if you build/buy the cable, and get the software, you can see what the engine is doing on a computer, preferably laptop.

    That is the very basic stuff. Some of the other guys on here can get into detail of it.........

    Are you asking where to get ALDL? If so, it comes on GM computer controlled vehicles, i.e. fuel injected ones.

    There are links on that site for the cable. Looks like about 40 bucks.

    I just built my own for about $10 buying all the parts. Just some wire, a clam shell, resistor, and a diode.

    Also, to make sense of it, your going to need a book. At least I did. BlazinOr (now BurbinOr) recommended "How to Tune and Modify Chevrolet Fuel Injection" (ISBN 0-7603-0422-X) which is very VERY useful for dealing with both TBI and TPI. Reading the sections on TBI will give you the knowledge to understand important numbers like BLM and INT along with proper ranges/meanings of all the other stuff.
