Technically the Tactrix can work all the way back to 99, but you need the definition files for the vehicle at hand in order to edit the ROM and those are not always available. Usually on 05+ cars you can find the file definition online somewhere. But the older the car the less likely you are to find one. ALSO - be VERY cautious with non turbo cars - the definition files aren't always as fully developed as they are for the WRX's, etc. It's literally someone's "best guess" with a hex editor as to what any given address in the ROM relates to. I've seen everything from the modifications doing nothing at all (seemingly) to making a single change to a check box for a code or for force readiness and having the car not even start and having to flash back to the old file. Knock on wood I've never bricked an ECU but I've come DAMN close to it. You can REALLY wreck your whole day with these tools. GD

OH, I'm sending 2 sheets I printed from that thread and one of them is the instructions I used. Doing some more reading/familiarization would be a good idea though. start a thread and report what you find/work on. Could be interesting to others.

If it has a hill holder, one channel splits at the hill holder, and the other will come right from the master (3 port master). If not, all 4 lines originate from the master (4 port). There's a proportioning valve in there somewhere in line to the rears, on the EJ cars, it's under the hood, but I think on the EA82s it's under the car in the rear.

Bleed the system really well afterwards. You might go through a few bottles of fluid (Don't resuse the new fluid that goes through the system), but its worth the cost of wasted fluid to not have air pockets in your brake circuit.
