Toyota GR86 Performance Tune
The Toyota GR86 builds on everything that made the original GT86 such a driver-focused car: rear-wheel-drive balance, low mass, and a chassis that encourages you to push harder every time you drive it. While the larger FA24 engine delivers more torque from the factory, it is still constrained by conservative torque modelling, limiter strategies, and throttle control logic that blunt response and mid-range urgency. The result is a car that feels capable, but never quite delivers everything the hardware is capable of. At AutoUpgrades, we see that as unfinished business. Our Toyota GR86 ECU calibration focuses on unlocking usable torque and sharpening response while retaining the OEM control framework that keeps the car refined and predictable.
During the tuning process, we work directly within the factory torque-based control strategy used by the Denso 115631-0010G ECU. By aligning torque request, calculated torque, and delivered torque, and optimising ignition and fueling, we allow the FA24 engine to deliver stronger and more consistent output across the rev range. This is not about chasing peak numbers. The real transformation is in how the GR86 responds to throttle inputs and how confidently it pulls through the mid-range. The car feels more eager, more linear, and far more satisfying to drive on real roads.
Key Features:
Increased Usable Torque: Engine torque modelling and request logic are recalibrated to unlock meaningful gains while retaining OEM safety strategies.
Improved Throttle Consistency: Torque-to-throttle mapping is refined to deliver a more predictable and connected driving feel without increasing maximum throttle angle.
Optimised Ignition and Fueling: Spark and lambda targets are carefully recalibrated to improve efficiency and response under load.
OEM-Controlled Operation: All factory knock control, thermal protection, and torque monitoring strategies remain fully active.
Power Gains: 2.4 FA24: +18HP, +25Nm
How It Works:
Morning Drop Off: Bring your Toyota GR86 to our workshop and discuss how you use the car and what you want to achieve from the ECU calibration.
Calibration Development: We recalibrate torque models, torque requests, ignition timing, fueling targets, and limiter behaviour directly within the factory ECU, with no software version changes.
Validation: The updated calibration is checked across all operating conditions to ensure smooth delivery, consistent response, and factory-level drivability.
Afternoon Pickup: Collect your GR86 and experience a car that feels stronger, sharper, and more cohesive every time you drive it.
The AutoUpgrades Toyota GR86 ECU calibration enhances what the car already does well. It does not change its character or compromise its refinement. Instead, it delivers a more confident and responsive engine that finally matches the capability of the chassis. If you want your Toyota GR86 to feel more immediate, more rewarding, and more complete from behind the wheel, this calibration delivers a genuine improvement you will feel on every drive.
