Ford Ranger gets a power kick with Texas Walker conversion

Possibly the most important and first part of the conversion is the fitment of a Unichip performance chip and plug and play system from the team at Dastek Power. The chip has been tested comprehensively on the two Ford TDCi engines and are optimised for South African driving conditions.


With the Unichip and plug and play system on board Ford Ranger owners can expect up to 20% more power and 25% more torque for the 2.2 TDCi engine and up to 20% more power and torque on the already impressive performance figures of the 3.2 TDCi Ranger.

The next stage of the Texas Walker conversion adds extra cooling through the fitment of a custom made Power Cooler to the 3.2 Ranger. This intercooler allows virtually double the amount of cold air into the engine, which allows the engine to breathe and perform even better. With this Power Cooler fitted, the team at SAC can also add a Power Switch. Together these two additions will give you complete control of your engine’s character from inside the cabin.Board

Says Stephen Fisher, founder of the Steves Auto Clinic group and well-known engine tuning wizard: “Our comprehensive testing of both the 2.2 litre and 3.2 litre Ford engines have confirmed that there is significantly more power available under the bonnet. By fitting a Unichip Plug and Play system we are able to tap into that power and, with the help of a Power Switch, the owner can dial into the power or choose a map that favours power, more technical or more frugal driving.”


The second stage of tune on the Ranger Texas Walker Unichip system with Power Switch offers five different driving maps. In its first setting, the Ranger enters a security mode, which renders the engine powerless and the vehicle unable to drive.

Notch the Power Switch up to the second setting and you will reconnect with your standard vehicle, as this setting mirrors the exact engine settings of the standard 2.2 or 3.2 engine. The third setting was created in response to many SAC customers’ need for better fuel consumption in city driving circumstances. In this setting the Ranger will deliver power gradually, with the benefit of better fuel consumption and greater travelling distances between fill-ups immediately evident.


The Texas Walker Unichip conversion adds two more unique engine settings that should be favourites among Ranger owners. The first of these two additional settings is an off road and towing option that changes the engine’s power band to deliver its peak power at lower engine speeds. For lovers of technical off road driving or people who regularly tow a large boat or caravan, this setting is ideal.


The last setting available through the Power Switch is the jewel in the SAC Conversion’s crown. Opt for this engine map and suddenly all of the hidden power in the TDCi engine comes rolling in like the dark clouds before a Highveld thunderstorm.

“Both the 2.2 and 3.2 engines have a large reserve of extra power that we have been able to safely and reliably unleash with our performance chip,” says Fischer.

Book the car inAt Steves Auto Clinic these conversions are done by a trained dyno tuning specialist, who maps engine performance in three dimensions against engine speed, load, fuel mixture, temperature and a host of other metrics. In doing so, the team ensures that each Ranger is optimised perfectly, with the vehicle’s age, condition and specific engine capabilities in mind.


For enthusiasts who would like to increase engine performance and efficiency even further, SAC has developed a brand new 76 mm performance exhaust system for the Ranger. This system, which has been developed specifically for the Ranger, ensures improved back pressure and a clear exhaust path to free valuable extra horsepower on the 3.2 TDCi engine.

“Every Steves Auto Clinic is equipped with modern diagnostic equipment and a dynamometer with which we test and fit any performance upgrades on the Ranger. With this equipment on hand you can be sure that we will safely and reliably add significant power and the choice of many different driving modes to your Ranger, so come in and have a chat with your local Steves Auto Clinic specialist,” says Fischer.
