Hi all Suby folks!

I have started to develop a new software to tune, log and flash Subaru ECUs. This project started an idea about year ago, to combine Subaru tuning support to my own standalone engine management system software, called FastECU. Time passed by and finally this summer I got a little kick to the project when user rimwall in RomRaider forum started project to mod NisProg opensource kernels to suit flashing Subaru ECUs with NisProg software. We put a little effort together and opensourced JDM Forester XT/Cross Sports ECUs to flashable! I call this fxt02 flashmethod for now on.

After that I decided that now is the time to start my tuning software project, as NisProg is command line tool, RomRaider does not support flashing (latest supports CAN-only ECU flashing via command line) and EcuFlash does not support all ECUs and is missing logging ability and is most likely also out of development. So, for now after few weeks of combining codes I have software which almost fully supports RomRaider editor definitions (support for nested base/inherit defs not yet added) and is able to open, tune and save HC16/SH7055/SH7058 ROMs (DTC disable option still missing, but coming soon).

This software is written with Qt 5.12.8 and it will work atleast on Windows 7+, both 32bit and 64bit and on Linux 64bit platforms. Possible to get working on Macs too but can't test it myself as I have only Linux and Windows machines. From NisProg I use modified opensource kernels and some snippets of code that are related to kernel read/compare/write ability.

So next steps are (not exactly in this order):

  • Adding sti04 (SH7055) flashmethod and open port 2.0 support (these I am doing now)
  • Adding sti05 (SH7058) flashmethod
  • Adding wrx02/wrx04/fxt02 flashmethods
  • Adding CAN flashmethod
  • Adding Diesel ROM support
  • Adding other Subaru ECUs (JECS/Hitachi etc.)
  • Adding logging support
  • Adding EcuFlash definition support
  • Adding Nissan ECUs support
  • Maybe other make/models too

I will release software for test use as soon as I have few flashmethods added and tested. This will be opensource software (under GPLv3), so source code will also be released after I have cleaned all unnecessary code from it (mostly my standalone ems code that has no use in it).
I also have my own forum for this project, found here --> https://www.syvanenmotorsport.fi/forum/index.php, that is meant to be the "base" for discussing of all things related to this software. There is already software to download to read and flash JDM Forester XT/Cross Sports ECUs. Note that this ECU is possible read and write only in car for now, haven't figured out yet what connections it needs to able to do it on bench.

This software will also support basic K-Line cables, so no need for Open Port 2.0 cable if there is no need to pulse 'Line End Check 2' -pin, that is needed for wrx02/fxt02 methods. I have myself used basic K-Line cable on fxt02 method development, I just soldered wire from FTDI-chip DTR-pin to pin9 (in Subaru FSM this pin is noted as pin8) on OBD-connector so no need for Open Port 2.0 at all.

Sti04 flashing method is working with generic K-Line OBD adapter and OP2 in both Windows and Linux. Next I need to add logging support atleast some level and test that wrx02 and fxt02 methods are fully working and then it's time to publish first test version.

Some updates and software is uploaded on github now. There is precompiled files for Win7+ and Linux.

If someone is testing this, please comment all bugs/issues/etc. on my linked forum. It's still very badly in progress due to little time between work and family and like to hear from people how they wan't different things to work.

Why not just extend ROMRaider with a definition and plugin to work with your ECU? What are you using as a test bench / dev environment?

I downloaded and installed the precompiled linux version and will see if can get working in my dev environment. If so, I will try logger and compare with similar RR outputs.

Not sure what you meant exactly by extending ROMRaider to work with my ECU, but this software is for OEM ECUs only, with capability to read/modify/write and log Subaru ECUs, later some other car makes too. Basic idea is have all-in-one software unlike others.

i guess my question is: What are you trying to differently the RomRaider? Is it just to support your stand alone ecu.. and if so, wouldnt it just be easier to add that feature to RomRaider?

I'm basicly doing software with all functionality in one software/gui to tune OEM ECUs. Software is just based on my standalone gui cause it was the easiest way.

EcuFlash does not have logging support and it's closed source so adding other ECUs and logging is not possible. RomRaider uses separate gui for tuning and logging, does not offer read/write except some CAN ECUs from command line and is written in java which is no for me :)

Later I will also add EcuFlash definition support to it and other ECUs (n/a models, other car makes) as I have time. It's just going to be one open source option with "all-in-one".
