You can find a complete listing of all the OE service sites at Once you’re on that web page, select the OE websites tab that is on the left of the page and read the information on programming. Next you will need access to the OE information. ![]() The laptop will need Windows Internet Explorer, Acrobat Reader and Java with NO virus protection.

Make sure you read their requirements before purchasing anything. Remember that not all OEs use the same requirements for software or hardware. If an aftermarket shop wants to get into the reprogramming business, they will need to have (at a minimum) a laptop or PC (Windows-based operating system), a solid high speed Internet connection, a J2534 tool that is proven compatible with the make you intend to reprogram, a subscription to the OE service website (or purchase access, usually on a one- to three-day basis) and the vehicle that needs the update. ![]() As with any software and hardware configuration, you have to make sure that your laptop meets the requirements for the OE that you are working on.

It sometimes goes by different names like ECU reprogramming, flash programming, Pass-Thru programming, calibration updating and software updates. J2534 is the regulated standard for installing software in onboard light duty vehicle computers.

The purpose of the MemCal PROM then and reprogramming today is to update the Engine Control Module (ECM) with the most current information.
