  1. It allows you to buy more licenses so you can have multiple platforms on the same scanner.


  1. I needed this to “re-learn” the new throttle body that I put on my 2010 Silverado. It worked perfectly ! Before I used this…. my idle speed was way off, and made driving difficult at best after I changed my throttle body. After aligning my throttle body with the scan tool it idled perfectly and drove nicely. It has many, many more features that I haven’t even used yet, but I’m looking forward to doing so in the future.


  1. I bought this to program fobs and replacement radio on my 2004 Cadillac cts. So far I’ve got my fobs programmed. So far this scanner is awesome. Only bad thing is downloading the programs. Its somewhat a pain.
