Landcruiser VDJ79 — Stage 2 ECU Tune
- torque elevation of approximately 200 Nm
- power increase of 34 kW at the wheels
- enhanced diesel engine responsiveness
- improved intercooler efficiency
- upgraded clutch capacity for increased torque handling
The 1VD-FTV responds well to better airflow and proper exhaust breathing. This Stage 2 file was developed for a 2022 VDJ79 fitted with a front mount intercooler, full exhaust system, and upgraded clutch to handle the additional load.
The workshop supplied dyno results showing 130 kW at the wheels, up from 106 kW stock, with torque climbing from 350 Nm to 515 Nm. That extra mid-range grunt makes a noticeable difference when loaded or towing across long highway hauls, particularly in summer heat where the larger intercooler earns its keep.
The clutch upgrade was necessary — the factory item won't live long at these torque levels. Fuelling and boost mapping were adjusted to suit the improved flow path while keeping everything inside safe margins for extended touring work.
Why is a clutch upgrade required for this power level?
The factory clutch in the VDJ79 isn't designed to handle 515 Nm. Without the upgrade, you'll face slipping and premature wear, especially under load or when towing.
Can this tune run on regular diesel?
Yes, the calibration is designed for standard Australian diesel. The power and torque figures shown were achieved on pump fuel.
Is the front mount intercooler necessary for Stage 2?
Absolutely. The additional boost and fuelling generate more heat, and the factory intercooler becomes a restriction. The front mount keeps intake temps in check, particularly during extended climbs or towing in warm conditions.
