A friend has is 05 sti tuned via open source tuning with a tactrix cable. Put down great numbers and cleared check engine lights. Is is possible to do this on our older subaru's ?

Thanks,
Jerry

So far the open source tools have been able to work with the Denso based ECMs. I thin maybe some of the later RS'es, but I don't think they are supported by the JECS ECMs.

like kmltick said, you have an obdII ecu. so you have one base covered. the other thing you have to figure out is if you have a denso or jecs ecu. to find that out you'll have to actually pull your carpet up and look at your ecu.

many rs's use jecs ecu's. subaru seemed somewhat random in doing this, as some rs's have jecs while others have denso. its not really something they changed yearly iirc. we have piles of ecu's at ecs and even some 00's used either jecs or denso. its the luck of the draw in what your car actually comes with.
