    Hey everyone,

    I know this is more of a haltech forum, but I was wondering if I might be able to get any information or if anyone knows anything about this model?

    I bought a used TRD 3RZ-FE supercharger kit, and this computer came along with it. I can't find anything about the computer itself, no part number or anything. The computers they're making now look nothing like the one I have. I did find some references to the T module or turbo module which I think is the small chip on top of the computer.

    I reached out to Unichip and they basically told me to kick rocks and they don't support models this old or have information on it. (But they'd be happy to sell me a new one of course)

    Anyone have any information on this, like how would I utilize this, wiring diagram, installation instructions, etc? Anything would help!

    That's shitty... Not a lot of wires there...

    At least they should be able to provide a manual or tuning software?

    Else tell them you'll be sure to document to thousands of people what their customer service is like

    It’s probably just a module that alters the MAF, O2 sensor, etc signals on its way back to the ECU, to provide additional fueling.

    Yeah that's what I asked for, unfortunately they said that it was 3 generations old and they no longer have any information on it

    This looks pretty close, though not sure what it gets you
