I'm looking for a good diagnostic program with data loging for my OBD1 LT1 for my lap top . I need it to moniter sensors and check for trouble codes .Diacom ? I'm not looking to spend a ton of money on it . Or can someone burn a copy if it is possible ?

I don't know about diagnostic programs, but you can get Freescan, of course for free, and TTS Datamaster is free for the first 20? logs. Both log data quite nicely, but neither has any real diagnostic routines built in.

Check out the AKM webpage, Andrew has a lot of information on this: http://www.akmcables.com/

Any other options ? has anyone used Diacom ?

 

From what I have seen, TTS DataMaster is the way to go. It is light years ahead of Diacom. Go to the Diacom website.... it was Popular Mechanics "Product of the Year" in 1991!!!!..... the dark ages. It is an antiquated DOS-based program, with a ridiculous price. I think if you want the limited graphing capabilities, you need the Diacom "Plus" or something like that, which is around $500. Not recommended, unless you have a stable of 1985-1995 GM cars of various brands that need a lot of scanning. DataMaster is limted to the OBD-I LT1.

They also misspell the name of the product as "Diatom" on one page...... .

DataMaster does have some features that aid you in diagnosing problems, or at least interpreting the data. On the BLM's for example, it will color code the cells that are deviating from normal, to indicate the magnitude of deviation. The only thing I have found odd in some of the data logs that people have sent me to look at is the numbers it produces for injector duty cycle... they just look way too high for the power some of these engines are making.
