Toyota LandCruiser 70 Series 2.8L (GDJ70 / 1GD-FTV) 2024-2026
Toyota Land Cruiser GDJ70 Series 2.8L Tuning (GDJ70 / 1GD-FTV)
About The Toyota Land Cruiser 70 Series 2.8L
The Toyota LandCruiser GDJ70 Series, powered by the 2.8L 1GD-FTV turbo-diesel engine, brings modern efficiency, emissions compliance, and refinement to the iconic 70 Series platform. While extremely capable from the factory, the stock calibration is heavily restricted to meet global emissions standards, resulting in conservative throttle response, muted torque delivery, and less-than-ideal drivability—particularly when towing or operating under load.
At Diesel & Performance Tuning Brisbane, we specialise in custom ECU and TCU calibration for the GDJ70 1GD-FTV, delivering measurable improvements in torque, drivability, and transmission behaviour while maintaining Toyota-level reliability.

Package Upgrades
Information about the upgrades included and available options for your vehicle.
ECU Remap
The factory ECU calibration on the 1GD-FTV V8 is highly conservative, particularly in torque delivery and throttle response. An ECU calibration optimises engine control, improving torque, drivability, and overall performance while maintaining safe operating limits for touring and towing. Key benefit: stronger, smoother torque with OEM-level reliability.
Includes:
- Preliminary Health Inspection
- Full System Diagnostic Scan
- Prelimary Test Drive
- ECU Software Update (Latest) With Factory Diagnostic Tool
- Prelimary Dyno Testing
- Prelimiary Data Logging
- ECU Calibration
- Calibrated Dyno Testing
- Calibrated Data Logging
- Final Dyno Test & Report
- Final Test Drive
TCU Remap
Frustrated with the indecsive shifting, torque converter flare, hunting gears, expecially when towing? Our Landcruiser GDJ70 Series TCU Tuning totally redefines the Aisin 6-speed transmission, addressing all of these issues by custom tuning the calibration to provide smoother, more responsive gear changes, complementing the enhanced performance of a professionally tuned engine. Pairing transmission tuning with our ECU remap is not mandatory, however, is extremely popular especially when towing. For best results, ECU and TCU tuning should be performed together.

- Preliminary Health Inspection
- Full System Diagnostic Scan
- TCU Software Update (Latest) With Factory Diagnostic Tool
- Prelimary Test Drive
- Prelimiary Data Logging
- TCU Calibration
- Calibrated Data Logging

Exhaust Upgrade
The factory exhaust system is a very restrictive, press bent, mass-prodiced unit, and increases backpressure once torque is increased. A 3.5" DPF-back exhaust improves exhaust flow, providing more efficient power delivery. 3" options are availble where space is of concern (toolboxes, trays, water tanks), as well as various combinations in 3"-3.5" single and twin exit, full systems from turbo-back for non-DPF models and systems compatible with airbags, GVM upgrades, coil conversions and more. We have you covered. Overall, an exhaust upgrade on the GDJ70 improves response, sound, and thermal control.
Includes:
- 3.0" or 3.5" Exhaust Upgrade
- Options for Single, Twin, GVM, Coil Conversion, Extension All Available - ***Please Advise**
- Gaskets Nuts & Studs
- Installation

Stage 1 ECU Remap – GDJ70 1GD-FTV
Our Stage 1 ECU remap for the GDJ70 2.8L 1GD-FTV is designed to safely unlock the engine’s true potential without requiring any hardware modifications.
Each calibration is:
-
Developed in-house
-
Dyno-tested and validated
-
Optimised for Australian fuel quality and climate
Key benefits of our Stage 1 ECU tune include:
-
Stronger low- and mid-range torque
-
Sharper throttle response
-
Improved towing performance
-
Smoother power delivery across the rev range
-
Improved fuel efficiency in real-world driving
This results in a LandCruiser that feels more responsive, more confident under load, and significantly easier to drive in everyday and touring conditions.
TCU Remap – 6-Speed Automatic Transmission
The factory Aisin 6-speed automatic transmission fitted to the GDJ70 is durable, but its stock shift logic is tuned conservatively. Under towing or heavy throttle, this can lead to unnecessary gear hunting, delayed downshifts, and excess heat generation.
Our TCU remap for the GDJ70 recalibrates the transmission to work seamlessly with the tuned engine, delivering:
-
Faster, more decisive gear changes
-
Improved torque converter lock-up strategy
-
Reduced gear hunting when towing
-
Better control under load and off-road conditions
-
Lower transmission temperatures in demanding use
When combined with the ECU remap, the vehicle feels significantly more cohesive and controlled.
Stage 1 ECU + TCU Tune – Dyno-Tested Results
Our Stage 1 ECU + TCU package is the most popular upgrade for the GDJ70 1GD-FTV, offering the best balance of performance, drivability, and reliability.
On the dyno, this package consistently shows:
-
Noticeable torque gains throughout the usable RPM range
-
Stronger mid-range pull for towing and overtaking
-
Smoother, more stable power delivery
-
Improved real-world performance without overstressing components
Unlike headline-chasing tunes, our focus is on usable torque and long-term durability, not inflated numbers.
Dyno Development & Validation
Every GDJ70 tuned at Diesel & Performance Tuning Brisbane is:
-
Dyno-tested before and after calibration
-
Logged under load to verify boost, torque, and temperatures
-
Tuned using OEM-level diagnostic tools
-
Validated for Australian towing, touring, and off-road use
Our dyno graphs reflect real gains you can feel, not theoretical results.
