Open source tuning for MazdaSpeed - RomRaider definition file(s)

[murphys_law]

New here, not new to cars or ECU/tuning stuffs. I got a bug and decided to start working on ecu definitions for this platform for RomRaider. I've got one up so far, but will probably start adding more as I collect them and get time. This first definition is only for a stock rom file speed 6 (no 2 step, big load maps, map switching, or any mods, yet)

I thought I would pop in and put up a post on it, just in case there are any geeks like me around here that enjoy ECU reverse engineering and disassembly.

Anyways, github is here: https://github.com/mrphyslaw/MazdaSpeedDefs

Just added another Speed 6 definition file. The goal will be to get a smattering of 3/6 roms supported in RomRaider for editing and then build a flasher/logger(I've already started) to enable open source tuning round trip. Hardware support so far will be tactrix devices, and the vLinker FS, because that's what I have access to. This ROM set/ECU is pretty cool because it has a robust OBD ECU recovery, unlike some of the Nissan stuff I've worked with in the past. Much easier to fix a bad flash via OBD than having to solder a bunch of wires and build a circuit to put the ECU in recovery mode.

Anndddd one more post for today since I'm in the zone on this at the moment. This is going to be the flasher/logger. Currently its python, as that was easiest to get a quick working prototype, but I'm going to convert it to C#/.net. Its got support the vLinker FS as of now and only dumps. It will correct checksums and do a read verification as well. I wanted to get it out in the wild and see if anyone wants to test, and the safest way to do that was dump only, for now.
