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

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. o_O
 
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.
