OTC offers Genisys, Snap-On has its programs, tools in the $5K or higher price range, aimed at shops doing pinpoint diagnostics and troubleshooting beyond code reader-based technology. Speedometer calibration was just the tip of the iceberg for functions you can perform with higher end, interactive scanners and diagnostic tools. You'll see the difference between uploading and downloading data. Click on the link and take the time to watch this video. I borrowed a DRBIII scan tool from friends at OTC/SPX Miller tools to produce the HD video on speedometer recalibration. Tools like the Chrysler DRBIII dealership level Chrysler/Jeep scan tool can actually reprogram elements of the onboard PCM or ECU/ECM software. From $1000 up would be programs that allow uploading information for permitted re-flashing of the vehicle's onboard computer. The next diagnostic scan tool tier is well over $1000, 10X the cost of the basic U-Scan reader. These simulations are essentially continuous reads of streaming data. Be aware that code readers and even their advanced apps are still talking only one way: from the PCM to the reader, whether receiving simple OBD-II or CAN BUS numeric codes or "watching" the sensor functions in real time graphic simulations or various graphs. U-Scan's upgrade "apps" are trendy and fit the Smart Phone culture. You do need the app upgrades to take full advantage of this technology. U-Scan is a Smart Phone view device and has a number of available upgrade apps that include real time sensor readouts. (Follow the link for all the details!) OTC/Actron/SPX/Miller are now all under the Bosch umbrella, which is a real plus for consumers. *Note that Powertrain flash files are supported through Chrysler’s Tech Authority website and requires a subscription, sold separately.JJ, I just received the latest Actron offering for testing: the U-Scan 9599.
This is the exact scan tool software application used in Chrysler, Jeep, and Dodge dealerships to service non-CAN based vehicles from 1998-2007.
