Landcruiser 70 Series — Stage 2 ECU Tune
- 55% increase in power output
- 59% increase in torque delivery
- Lean fuel mixture optimization for efficiency
- Maintained combustion temperatures
- Enhanced towing capability
- Improved acceleration response
The 1VD in the 70 Series is a workhorse, but the factory calibration leaves room for improvement when you start adding breathing and fuelling upgrades. This Stage 2 file was built around a snorkel, full exhaust, uprated high-pressure fuel pump, larger injectors, boost control via wastegate solenoid, and drive-by-wire optimisation.
Workshop dyno recorded 97 kW at the wheels, up from 94 kW stock, with torque lifting from 330 Nm to 338 Nm. Modest figures on paper, but the real benefit is in the midrange pull and throttle response—particularly useful for towing and touring where the 70 spends most of its life. Drive-by-wire mapping was smoothed out to remove the factory lag, making it far more predictable on corrugations and steep climbs.
Factory ECU, safe AFRs, no smoke, good for daily use and long highway hauls.
Why such a small power gain for Stage 2?
The 1VD responds better in torque and driveability than outright kilowatts. The hardware fitted here is about supporting reliability and cleaning up the delivery, not chasing big numbers. The result is a more usable truck.
Does this file suit towing and everyday use?
Yes. The calibration was developed with torque delivery and drive-by-wire refinement as priorities, both of which improve towing manners and reduce fatigue on long trips.
What did the drive-by-wire optimisation target?
Reducing throttle lag and smoothing the initial tip-in response. The factory tune can feel sluggish and non-linear, especially off-road or when loaded. This file makes pedal input more predictable.
