Their are tune systems that access toyota vw and lots of other cars, afaik all manufacturers have some kind of lock sequence you cannot just read it out without cracking some form of key sequence. Im sure subaru could make it more difficult if they wanted though as could all manufacturers.

Most aftermarket tunes dont comply fully with emmissions in most countries but thats another issue



They also dont tell anyone about how the ecu works or tavle locarions or functions its all reverse engineered from the ecu code.

I believe the e-tunes from Feb 2019 on have all been done by Bill!

how does that work? wouldnt zach be unable to access the old CSG/DT tune since DT has the key?
