How come Ecut*k can do it?
Because Stephen Done (the original brains behind what became Ec*t*k) put in the hard yards and resource to suss it out, and once having done so, decided to make a financial return on the time investment he'd put in.
Where it gets slightly more contentious is that he was, in the early part of his research, posting in an open source Yahoo group. Slightly ironic, if nothing else, in the context of Ec*t*k's subsequent position regarding other open source projects.
How are people getting the flashes that have already been posted?
That's easily done, as mentioned in another thread. Think most of the PC-based clients have options for ROM downloading, but if not you can do it via the A0 "block read" SSM command.
I have two 99-00 cars sitting here, both AE802's. one is standard, one is either Prodriv* (PPP) or Ecut*k. I want to get/try the decent map on the standard one.
If it was as easy as that, we'd all be doing it! Unless something has changed in the recent past, Flash99 (i.e. Ec*t*k) is the only gig in town for updating the stock ECU. Colby (the originator of this site, and the OpenPort interface) was originally going to look into the JECS ECUs after sorting the Denso-based Subarus, but seems to have gone more into the Evo, DBW and other areas.
A few of the rest of us have spent some time on it, but the lack of datasheets for the processor used has made it very difficult to make any progress. I'm starting to think it'd be less hassle and time to design and build an ECU from scratch than it would be to fully reverse engineer the JECS one!
