Toyota Tacoma 2.7L OTT Tuned ECU (4-Cylinder Models)
Unlock improved drivability and responsiveness in your Toyota Tacoma 2.7L 4-cylinder (2TR-FE) with a professionally calibrated ECU loaded with the Overland Tailor Tuned (OTT) by Big Dawgs Toyota Tuning.
From the factory, 2.7L Tacomas are reliable but often feel underpowered and sluggish — especially with larger tires or added overland weight. This tune increases throttle response, improves drivability, and delivers smoother power delivery across the RPM range.
Perfect for daily drivers, work trucks, and overland builds.
This is a 2.7L 3rd Gen Tacoma model ECU. It is updated with the latest Toyota TSB and tuned with the newest OTT calibration.
ECUs are year & drivetrain specific. They are not interchangeable. Please double-check that you select the correct model year for your vehicle before ordering.
You’ll remove your factory ECU and install the tuned unit using the included step-by-step instructions. No additional tuning or programming required.
Please note: a $350 core charge is applied at checkout and will be fully refunded once we receive your original (stock) ECU & verify its working condition.
Once purchased, you will receive an email requesting details about your truck. It is pertinent you respond with the information requested.
Warning! Installation of this ECU incorrectly may result in ECU/TCU failure. Please contact Big Dawgs Toyota Tuning if you have any questions.
