Description
The Renesas processors are usually found on Japanese-built control units and are quite common more on Japanese vehicles than on their Western counterparts. The most famous families are SH705x and SH725xx, which are widely used from 2005 to today. Denso is a ECU manufacturer that vastly uses Renesas processors. These OBD & bench protocols allow for full ECU access: both internal flash and internal EEPROM can be entirely read and written as a backup file for cloning and restoring purposes, and Flex allows to read and write maps directly, as well as calculate checksum for all the tuning enthusiasts. At the moment the special protocol seems to work on specific ECUs, but we are constantly expanding our technology and we are already looking for some extra unit to add to the list.
