2 engines, 1 ECU part-number family. Find the controller your car runs, then clone it onto a donor or adapt it remotely.
Engines and their ECUs
| Engine | Engine codes | ECU family | Model code |
|---|---|---|---|
| 4.0 V6 / 4.6 V8 | 1GR-FE, 1UR-FE | Denso Gen1 (NEC 76F00xx) / Denso Gen2 (D76F01xx / 02xx) | |
| 4.7 / 5.7 V8 | 2UZ-FE, 3UR-FE, 3UR-FBE | Denso Gen1 (NEC 76F00xx) / Denso Gen2 (D76F01xx / 02xx) |
Tow-package trucks carry their own ECM number — a non-tow donor is a mismatch even on the same engine.
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 Tundra / Sequoia 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 2007–2021 Tundra / Sequoia have?
It depends on the engine. The 4.0 V6 / 4.6 V8 (1GR-FE, 1UR-FE) runs Denso Gen1 (NEC 76F00xx) / Denso Gen2 (D76F01xx / 02xx), model code 89661-0C. The 4.7 / 5.7 V8 (2UZ-FE, 3UR-FE, 3UR-FBE) runs Denso Gen1 (NEC 76F00xx) / Denso Gen2 (D76F01xx / 02xx), model code 89661-0C. The label on your module settles it in seconds.
Can you clone the ECU on a Tundra / Sequoia Second generation?
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 Tundra / Sequoia 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.
