SAC introduces “Lekker Ou Jan”

“Lekker Ou Jan” – not a name you’d think would be associated with a performance upgrade, but Steve’s Auto Clinic (SAC) has chosen the name for its Isuzu KB300 D-TEQ upgrade as “a way of paying homage to the trusty old plaasbakkies”.

The culmination of the testing and development of a Unichip with PowerPlug for the 3,0-litre D-TEQ optimises power delivery and improves fuel consumption.

“With the ‘Lekker Ou Jan’ performance upgrade, we have utilised the full power of Unichip, and the difference in engine performance will be immediately evident, thanks to an improvement of 30 to 40 kW in engine power, up to 170 kW, and a jump in torque from 380 Nm to around 490 Nm,” says Stephen Fischer, founder and CEO of the SAC Group.

For the performance upgrade, the Unichip Q4/PowerPlug plug-and-play combination precisely controls fuel and boost pressure with a timer control. It also allows for certain maps to override the fuel injector settings for improved fuel consumption, or greater performance.

The Unichip also monitors engine temperature to ensure that the engine remains within its standard safety parameters at all times, while delivering more power.

The Isuzu D-TEQ’s additional power can be easily controlled by the driver, thanks to the inclusion of a Power Switch. The switch allows the driver to switch between five different pre-programmed performance maps on the fly.

The first map removes all engine power and ensures additional security when the vehicle is stationery. With this setting, the driver simply removes the Power Switch and carries it with him, leaving the vehicle almost impossible to drive.

Another map is a special 4×4 and towing setting, which optimises torque delivery at low engine speeds for technical off-road driving, or towing a heavy load.

“By optimising engine performance, the driver should experience improved fuel consumption in any of the performance settings, but in Fuel Consumption mode the improvement can be as much as 15 percent, depending on environmental conditions and driving style,” says Fischer.
