Overland Tailor Tuning (OTT) is proud to announce the official release of our highly anticipated ECU and TCU tuning solutions for the 2024+ Toyota Tacoma, featuring the 2.4L (T24A-FTS) engine in both gas and hybrid variants.
After more than 6 months of extensive development and in-house testing, OTT is excited to offer a precision-engineered, comprehensive tuning solution designed to optimize performance, enhance drivability, and improve reliability.
For those who are familiar with OTT from our work with the 3rd Gen Tacoma, you’ll find the same high level of commitment and precision in the new models. OTT’s tuning is designed with a focus on real-world reliability and performance, not just raw power—though the new platforms certainly deliver a punch! In some cases, they provide more than three times the gains compared to what was possible with the previous naturally aspirated platforms!
Key Features of OTT’s New Tuning Solutions:
• Reworked Throttle Control Strategies: The new generation ECUs feature a completely new throttle control strategy compared to previous Tacoma generations. With this new strategy, we offer throttle sensitivity options of “Stock,” “Base,” and “Enhanced,” allowing drivers to tailor their vehicle’s throttle response to their preference, replacing the previous “Lite,” “Mild,” “Medium,” “Spicy,” and “Super Spicy” naming conventions.
• Enhanced Throttle Response and Reduced Spool Time for Turbocharger: OTT’s tuning sharpens throttle response and reduces turbocharger spool time, allowing for more immediate low-end and midrange torque. This means the engine reaches usable boost pressure more quickly, improving drivability and acceleration, particularly during off-the-line starts and when accelerating from low RPMs. This results in a more responsive driving experience, with faster throttle reactions all with smooth delivery.
• Stage 0 Customization: OTT offers Stage 1 and Stage 0 tuning solutions, with TCU updates for each drive mode to enhance driving performance. Stage 0 is available on request for those requiring reduced output at lower boost levels.
• SR Trim Calibration Option: OTT will offer the ability for SR trucks to receive “OEM Spec” calibration updates, bringing the base trim to the full output of the higher trim trucks. SR Trim vehicles are also supported in Stage 1 and Stage 0 configurations.
• Fuel Requirements: OEM Spec through Stage 1 calibrations are designed for Regular to Premium fuel, with peak performance achieved on Premium (Recommended).
• Exclusive Calibration Capabilities: One such ability is OTT's offering of a proprietary MAF calibration that ensures perfect integration with a retrofitted TRD Pro/Trail Hunter airbox, without triggering CEL codes. In addition, OTT is developing solutions such as Auto Start-Stop disable and other advanced vehicle customization options (to be announced at a later date).
