Bring your Isuzu into its own
The secret to more power
Did you know that there is between 70 & 100 Nm of additional torque waiting in the D-TEQ engine of your Isuzu KB300? With the new “Lekker Ou Jan” conversion kit from Steve’s Auto Clinic you are mere minutes away from unleashing that power!
The Lekker Ou Jan Conversion is the culmination of the testing and development of the Unichip with PowerPlug for Isuzu’s D-TEQ 3.0 turbo diesel engine. It utilises the full power of the Unichip and PowerPlug to not only optimise power delivery, but also to improve fuel consumption.
To bring out the best in the 3.0 D-TEQ, the engineering team at Steve’s Auto Clinic have programmed the top of the line Unichip Q4 to monitor and control multiple aspects of the engine at the same time. This is in stark contrast to most of the “off the shelf” performance upgrade chips, which simply increase fuel pressure, no matter the engine coolant temperature or boost pressure.
In the Lekker Ou Jan conversion, the Unichip Q4/ PowerPlug plug and play system controls fuel pressure, 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 D-TEQ remains at all times within its standard safety parameters, while delivering more power.
“With the Lekker Ou Jan conversion, we have utilised the full power of Unichip and the difference in engine performance will be immediately evident, thanks to an improvement of 30-40 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.
The Isuzu D-TEQ’s additional power can also be easily controlled from inside the cabin, thanks to the inclusion of a Power Switch. The switch allows the driver to switch between different performance maps on the fly, choosing between different pre-programmed settings.
There are five standard performance maps pre-programmed into the Lekker Ou Jan conversion. The first map removes all engine power and ensures an additional layer of 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.
The second map returns the Isuzu D-TEQ to standard, with no change in performance or fuel consumption, while a third map changes engine characteristics and performance to dramatically improve fuel consumption.
“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%, depending on environmental conditions and driving style,” says Fischer.
The remaining two maps offer the best in engine optimisation. One of these is a special 4×4 and Towing setting, which optimises torque delivery at low engine speeds for technical off road driving or when the Isuzu tows a heavy load. This setting should be ideal for people who chose the Isuzu for its high load and tow ratings, which remains one of the best in class.
In the final setting, the engineers at SAC come into their own and the D-TEQ delivers optimal power. In this setting, all latent power is made available to the driver, giving him a very rewarding driving experience, while maintaining engine durability and safe operating conditions.
Throttle boost added
As an additional feature, SAC has added a throttle boost option to the conversion. This additional control module ensures smooth acceleration and improved throttle response, regardless of engine speed and it removes the so-called flat spot that many D-TEQ owners have experienced when accelerating hard through the rev range.
“We chose the name “Lekker Ou” Jan as homage to the trusty old ‘plaasbakkies’ that we all know. From those early days, Isuzu has established itself as a manufacturer of trusty and reliable pick-ups and it remains a very popular option. Today, we allow owners to dramatically improve their driving experience, fuel consumption and performance, while maintaining the reliability that it has become known for,” says Fischer.
The primary function of an upgraded intercooler is to improve on the cooling efficiency over the standard cooler. This means that the entry air temperature needs to be dropped as far as possible (more than the standard cooler) at the exit of the cooler without compromising or interfering with the flow and or charge pressure- the boost. Our upgraded intercooler has been through very strict Research and Development procedures and has been properly tested to meet the requirements of today’s technologically advanced and challenged Diesel Turbo vehicles. The new cooler mounts in the same location as the standard one and in most cases, utilizes the original pipes and clamps. (With the exception of the D4D Hilux that goes from top mount to front mount) The intercooler upgrade is an integral part of the performance enhancement process that optimizes the volumetric efficiency of a TDi Bakkie. In short, the way that the cooler works is to cool down the air as much as possible – that is being produced by the turbo charger (that heats up when compressed). Fast-hard riding as well as towing causes thermal engine temperature creep which eventually spirals out of control and deteriorates your vehicles engine condition and shortens its life. It’s not only about more power, sometimes we need to consider what the engine is being exposed to and have some mechanical mercy. Our upgraded intercooler is an absolute “must have” product for those performance fanatics out there, or the people that want maximum power at safe levels.

Bolt on exhausts
Gone are the days that you take your half a million-rand Bakkie to a corner exhaust shop for a cheap free flow exhaust. It’s fair to say that the bolt-on free flow exhausts of today at SAC have been revolutionized and are becoming more and more popular amongst the enthusiasts. It is no longer just a poorly welded and routed exhaust that rattles and knocks over every bump, it is a properly engineered, big bore, mandrill bent stainless steel-low restriction exhaust system. It is manufactured in such a way to be a bolt-on fitment in a workshop with very little effort to ensure perfection. Seeing the exhaust system in its raw form, packed and laying on a shelf – it is clear to see that this is an export quality product that will be installed on your vehicle, and it will compliment without any doubt – the performance enhancement plug and play kit and or upgraded intercooler system in many ways – most of all the sound and power will be much improved. The bolt-on exhaust system is routed along the exact same rout under your vehicle and hangs with similar brackets on the standard rubbers. The heat protection that has been provided by the manufacturer under your vehicle to protect the undercarriage is still effective and useful with the fitment of these bolt-on exhaust systems.
