Toyota's 2GR, 2AR and D-4D diesel engines offer ECU tuning potential, particularly the 2.8 D-4D diesel in the Hilux and Land Cruiser Prado, and the turbocharged 1.8T in the new Yaris GR. The GR Supra with BMW B58 is an outstanding tuning platform.
The Toyota GR Supra with B58 3.0T six-cylinder responds to Stage 1 with +50–80 Nm — exceptional results on this BMW-based platform. The Hilux with 2.8 D-4D diesel delivers +45–65 Nm. The Yaris GR with 1.6T three-cylinder responds to Stage 1 with +30–50 Nm.
Toyota ECU tuning covers OBD port access for D-4D diesel and GR models. The Supra uses BMW-standard tooling. All calibrations preserve Toyota safety systems. Fully reversible to factory specification.
