OK so I'm driving my supra to vacation a 3 hr trip and i hit little traffic and it cuts off with out any warning never over heated or anything. So i pop the hood and check around and nothing looks wrong so i pull a hose off to cause a vacuum leak and she starts up fine . I decided to say fuck it and drive it anyways and she then wont hit boost sputter like shit and starts to burn rich as shit i couldn't even drive it so i plug the vacuum back in and the idle drops dramatically and when you give i gas she revs up spools ans when it comes back down cuts off . i yank the map off and nothing happens any ideas ?

Did you bother checking for codes? I would start there first and see what it says. I am going to go with the ecu just took a dump on you though.
might not be the ECU could be something as simple as FPR just needs adjusting or replacing. Or maybe an injector that is stuck open
Unfortunately you always start diagnosing with the ECU on these cars. It tends to be the problem about half the time lol.
check your IC pipes? mine pooped off once and did the same thing. but i would look in to the ecu if its not been re caped I'd have it done.

Went through 2, and said fuck it. I now have an aristo ecu on the stock 1jz harness.

No, but you can buy/build an adapter harness, and you'll have to run 3 additional wires for the sequential injection system of the aristo, and you'll have a reduced rev limit.
I would recommend repairing the ECU first. I fixed mine 2 years ago and it's been fine since then.

That is kinda wild. I would never expect an O2 sensor to just go like that. Good job figuring that out!
