Supra A90 — Stage 2 ECU & TCU Tune
- Torque increase of 116Nm
- Noticeable gains in low-end torque delivery
- Improved overall drivability and throttle response
- Faster and more refined transmission shifts
- Enhanced mid-range performance
The A90 Supra platform responds well to a considered approach. This build pairs downpipe and intake hardware with custom ECU mapping and XHP transmission tuning to deliver 281.6 kW at the wheels, up from 234 kW stock. Torque climbs from 431 Nm to 547 Nm, giving the car a noticeably broader mid-range pull.
The XHP transmission calibration is key here. It sharpens shift behaviour and holds gears longer under load, complementing the ECU changes without sacrificing street manners. This is a well-rounded Stage 2 setup suited to spirited road use and closed-circuit work, with gains that justify the investment without pushing beyond the factory bottom end.
The combination of intake, downpipe, and dual calibration keeps the package reliable on 98 RON while making the most of the B58 architecture.
What does the XHP transmission tune change?
XHP tuning adjusts shift points, firmness, and torque converter lock-up behaviour. It works alongside the ECU tune to hold gears longer and deliver crisper shifts under throttle.
Is this build safe on standard internals?
Yes. The power and torque figures sit comfortably within the factory engine tolerance, especially on 98 RON. The supporting mods allow the tune to extract gains without leaning on timing or boost beyond sensible margins.
Can I run this tune on pump fuel?
This calibration is designed for Australian 98 RON. No fuel type was specified, but the gains suggest safe tuning margins for premium unleaded.
