With already impressive performance in standard form, the Nissan Navara can at times be lacking in low RPM punch. When heavily loaded or towing, the lack of torque is even more pronounced - necessitating higher engine revs in a lower gear - and poor fuel economy.
By making fine adjustments to the EFI strategy - particularly to the injection timing settings, significant gains are made with Dtronic across the entire RPM range.
Right from 1,000 rpm, Dtronic boosts the engine torque by an outstanding 20% - and at only 1200 - 1300 RPM, the Dtronic enhanced Navara produces more torque than the standard engine's peak output.
When the going gets tough, Dtronic delivers more. As can be seen from the table below, Dtronic provides an additional 64 Nm of torque at 2,000 RPM for an outstanding total of 380 Nm and an equally impressive boost of 16 kW at 3,500 RPM for a peak power figure of 126 kW.

In order to produce these outstanding results, accurate injection timing control through the Dtronic computer is an essential function.
Accurate injection timing control is also critical not only for the best possible fuel consumption, but also to control peak exhaust gas temperatures for optimum durability.
The Dtronic computer can be simply unplugged at any time - thus returning the vehicle back to factory ECU control.
The Safari Dtronic computer provides significant benefits in both on and off-road operation:
- improved acceleration for safer overtaking
- maintain comfortable cruising speeds when towing in undulating conditions
- improved 4x4 performance in both desert and high country terrain
- improved throttle response for finer vehicle control in technical 4WD conditions
- improved acceleration after installation of increased diameter tyres
- improved towing performance
