Toyota / Lexus / Scion engine ECU cloneOn-car software step — remote Techstream, $250
Some cars still want an on-car step after a module swap — an ECU communication ID registration on a smart-key car, a calibration update, or a key registration. Plug a J2534 pass-thru interface into the car and we run the factory Techstream software on it from our bench — no dealer visit. The same session covers programming after any other Toyota or Lexus module replacement.
