Reflashing Program from Subaru
Posted: Tue Apr 03, 2007 2:16 pm
This month Subaru of America will release a program to the public which can reflash Subaru ECUs. The program is compatible with Windows 98 and above and requires an SAE J2534-compatible device and application programming interface (API).
It seems like it should be possible to trace that program's calls to the J2534 API and capture the data being sent to the ECU. This data should include the kernel.
If support for J2534-compatible devices were added to EcuFlash, then it would be possible to take a shortcut to support for the non-Impreza 2007 ECUs and all newer model year Subarus, which apparently require CAN support for reflashing.
A description of the J2534 API can be found at http://www.drewtech.com/support/j2534/index.html. Of course, the definitive description is the standard itself, which can be purchased here.
The cheapest place I've found to buy a J2534 device and API is at Tuner Tools. It's $275 there and if you enter the coupon code Enginuity, you get a 5% instant discount. The Mongoose should work with all 32-bit Subaru ECUs plus it comes with free OBD-II scan tool software.
