NissanDefinitions

Nissan and Infiniti ECU ROM Definitions for use with RomRaider Editor.

About

Current Stable RomRaider Version: v1.0.0

NissanDefinitions supports ECU ROM definition files for SH7055/SH7058 Nissan and Infiniti ECU's. These definition files are formatted to be compatible with RomRaider. Vehicles with these ECU's typically includes model years between ~2001-2010.

Each ROM has its own definition file that stores the ROM addresses for all defined tables. This definition file references the A2L template file, which contains table specific data. The ScalingData file is where all table scalars are stored. Using the "Combine All.bat" file will merge all files into one. As time goes on, more and more ROMs will be defined.

Important Notice

Due to RomRaider no longer allowing bitwise switches larger than four bytes, DTCs are currently in a very dysfunctional state. So while DTC addresses will be accurate, the actual DTCs you'll see have no guarantee of accuracy. So I'd highly recommend not altering DTCs for the time being.
