The model code is the family-level part of the label (for example 89661-06X91). A donor must match the full number, which we confirm against your VIN for free before you buy.
Clone the Lexus GS ECU — $350 flat
Mail your original and a donor with the same full part number. VIN, immobilizer data, coding and adaptations are copied across on the bench, typically within 24 hours of arrival. Factory immobilizer stays on.
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.

Which engine ECU does a 1998–2020 Lexus GS have?
It depends on the engine. The 3.0 / 3.5 V6, 4.3 / 4.6 V8 (2JZ-GE, 2GR-FSE, 3UZ-FE, 1UR-FSE) runs Denso pre-CAN engine ECU → Denso Gen1 (NEC 76F00xx) → Denso Gen2 (D76F01xx / 02xx), model code 89661-30. The 3.5 hybrid (GS450h) (2GR-FSE / 2GR-FXE) runs Denso Gen1 (NEC 76F00xx) / Denso Gen2 (D76F01xx / 02xx), model code 89661-30. The label on your module settles it in seconds.
Can you clone the ECU on a Lexus GS S160 / S190 / L10?
Yes — every engine ECU on this generation is a routine bench clone. Mail your original and a donor with the same full part number and we copy the VIN, immobilizer data, coding and adaptations across for $350 flat, typically within 24 hours of arrival.
Will a cloned Lexus GS ECU need dealer adaptation?
Usually not — it leaves the bench carrying your VIN, immobilizer data, coding and adaptations. If the car still asks for an on-car step, we run it remotely with Techstream over your J2534 interface for $250.
