Plug 'n Play - FAQs

SAC, South Africa’s leading performance tuners, are able to offer extraordinary levels of expertise in Engine Management Systems (EMS), Electronic Control Unit (ECU) chipping, modifications & upgrades, with guaranteed results.

The U-Connect – Power Plug intercepts the signals from the engine’s sensors and allows the ECU’s original pre-set MAP to be altered and enhanced.

These modifications allow the engine to reach its full potential in terms of power, fuel consumption and drivability.

The U-Connect – Power Plug is fitted by professionally trained tuners with Original Equipment Manufacturer (OEM) ECU connectors which are specific to your vehicle’s model, so you simply unplug the vehicle’s wiring harness from the ECU, plug the vehicles harness into the Power Plug and plug the Power Plug harness into the ECU.

Currently it is the only unit on the market with the capability to intercept and modify all sensor and actuator signal circuits.

For an additional performance increase, U-Connect – Power Plug is the only unit that can be individually tuned to your vehicle while live on a dynamometer.

This means that an ECU MAP specifically optimised to your vehicle can be achieved.

The U-Connect – Power Plug is also re-programmable, so when any modifications are made to your vehicle, (i.e. exhaust, camshaft, etc.) the Power Plug can be re-mapped to adjust the ECU’s parameters to take full advantage of these alterations.

This will only involve a further rolling road session to once again optimise your engine’s settings.

For additional safety these U-Connect – Power Plugs can be fitted with their own exhaust gas and coolant temperature sensors that continually monitor and if necessary alter the fueling to safeguard the engine.

Most other diesel plug products only adjust the fuel quantity. The speed or load of the engine is rarely taken into account during this adjustment, and they are incapable of adjusting the point of fuel injection.

These limited scopes of adjustment leads to an inability to control smoke output, critical combustion temperatures, and pressures.

Dastek are able to alter the fuel quantity and injection timing of over 476 individual points of the engine speed hwile live, and load MAPS to provide the optimum combination of performance, economy and safety.

This is done using a rolling road dynamometer, a device which accurately measures your vehicle’s power to 1/10 horsepower, and precisely monitoring these critical temperatures, pressures and smoke emissions.
