There is a saying, "If it's too good to be true...." Take a look a this: http://www.digimoto.com/

 

I have one. Bought it for $99 on ebay. Looks like a real quality piece. I don't have any cars with OBDII PCMs at the moment so can't comment on how it actually works (sold the car I bought it for soon after I bought it. DOH!) but I remember when I bought it that it did quite a bit of cool stuff!

 

interested in selling it? Are you still working on the Domed Letters?

 

I have a number of friends who come over and fix their cars at my house so was going to keep it as a diagnostic tool for the "shop"

Domed letters should be available in less than 2 weeks
