Some bugfixes and sti05 flashmethod confirmed. https://www.syvanenmotorsport.fi/forum/index.php?topic=15.msg16#msg16

Another update with EcuFlash definition support and some bugfixes https://www.syvanenmotorsport.fi/forum/index.php?topic=15.msg16#msg16

More updates to software: https://www.syvanenmotorsport.fi/forum/index.php?topic=15.msg32#msg32 https://github.com/miikasyvanen/fastecu-oem

https://www.syvanenmotorsport.fi/forum/index.php?topic=15.0 Some updates, software is 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.

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.

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 [b]rimwall[/b] in RomRaider forum started project to mod [b]NisProg[/b] 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. - Miika Syvänen

I think you need to lock the tgv valves to open position.

Could also be that some gear is missing a tooth or part of it etc. When foot off the clutch, input shaft and gears are rotating with engine, so if there is something broken it will make a noise.

Hi everyone! My name is Miika, I am owner of car tuning/maintenance business in Finland near Helsinki called Syvtech Inc. I've been working with Subarus since 2006, and about 8 years now make it for living. Some 10 years from now, I started developmenting engine management system for Subarus, starting from idea to get older Subarus fully tunable for reasonable price. First, it was just hobby, based from interest how everything works and started with using 8-bit ATmega128 microcontroller just because I have many of them on the shelf from other projects. Later, as I was still working on other automotive related company, I started coding with STM32F4 in one project and started thinking that maybe I should boost my ECU project "little bit" with it So now I have new version of it with whole new design and goal to use it with Subarus all the way from year 1990 to at least 2007 or so. And of course other car make/models too. At this moment, I have plug'n'play versions that fully supports gen1/2/3(rev a/b/c) Legacy turbos (yes, also 3gen JDM twin turbos, 2gen untested), Impreza GC8/GF8 turbos and Forester SF turbos. It also works nicely with N/A cars that share same pinout with turbos, e.g. 2gen Legacy EJ20 N/A, only thing to add is MAP to get it running. Adding IAT is recommended of course but not necessary. ECU is based on design that all share the same controller board and has only car specific connector on the base board so changing from version to another need only to change the base board. Newage versions are under testing, supporting TGV, AVCS and ETC, also OBD and CAN is coming and DCCD control. EZ30 AVCS/AVLS and other N/A versions will be available at some point. Only thing that will not probably be working (haven't tested and coded) on older ECUs is narrow band O2 sensor, so if one want closed loop control, wide band sensor should be used. Also newer type stock wide band AFR sensor will be working in the future. Knock sensor feedback control software is under development. Tuning software uses live tuning, so results shows immediately, and after satisfied just store to eeprom. ECU will also later support bluetooth, that will be used mainly for monitoring, e.g. android tablet to show gauges, but tuning is also possible via bluetooth. Here's pic from 3gen Legacy ECU that will control electric throttle and intake AVCS in my car: https://www.syvtech.fi/wp-content/uploads/2021/05/1620227721799.jpg And pic from tuning software: https://www.syvtech.fi/wp-content/uploads/2021/05/1620227721799_2.jpg If here is interested people to support this project, get these for testing and help me to add/improve features, give ideas how things should be etc. price will be 500€+postage for now, and everyone who buys this now get new "full" version with 30% discount when it's ready. Both sets includes base and controller boards. If any questions etc. whatever, feel free to send me a message anytime!
