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.
Right. It's intended to allow independent repair shops to reflash ECUs, allowing them to be more competitive with dealerships. EPA rules require it.Freon wrote:Interesting. So presumably this is just a tool to update to newer Subaru calibrations, not to say it couldn't be hijacked?

Also, I imagine the likelihood, that STIS would ship one of these CD-ROMs directly to a non-US address, is very small.
Call Subaru's Service Technical Information Company, toll-free, at 1-866-428-2278 and tell them you want to purchase the Subaru J2534 Pass-thru Reprogramming CD-ROM. The software is on the CD-ROM. Cost is $75 plus S&H and any applicable state sales tax.cboles wrote:How does one actually obtain this software though?

Yes, this might be a technique for discovering how to reflash other brands. For instance, you can download Nissan's J2534 Windows program for free from http://www.nissan-techinfo.com/Nissan/consult2/Nissan-CONSULT-II-J2534.exe (9 MB). But you have to buy each data file containing the ROM data that will be reflashed.salex wrote:The J2534 protocol seems like a good solution to learning a lot for ECUs we know nothing about. Not only for Subaru, but also for all the other manufacturers who have to provide this type of support to smaller garage shops.
