As vehicles become more computerized, the requirement to reprogram those modules is more and more necessary. AutoEnginuity's J2534 reprogramming hardware meets that requirement.
The AutoEnginuity VSI-2534 is a J2534-1 and -2 compliant device and is a stand-alone hardware solution. If you have already reprogrammed modules you will understand how helpful this feature can be. It is not integrated into the ScanTool product to help a shop prevent tying up a computer station with the lengthy process of reprogramming modules.
The J2534-1 Specification covers emissions-related reprogramming which is typically the Engine Control Module and/or Transmission Control Module. The J2534-2 Specification covers everything else. The OEM's aren't mandated to be -2 compliant, but only -1. Everything else is "optional" to the OEM. GM, Ford/Mazda and Toyota are the main OEMs releasing -2 programming calibrations to the Aftermarket.
The J2534 Specification specifically states that calibration data for vehicles 2004+ must be made available by the OEM and that the J1962 connector is to be used. While some manufacturers support earlier vehicles, the J2534 Spec states that manufacturers only have to support 2004+ later vehicles for J2534 programming.
