Plug 'n Play - FAQs

SAC, performance tuners, are able to offer extraordinary levels of expertise in Engine Management Systems / EMS, Electronic Control Unit / ECU chiping, 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 it’s full potential in terms of power, fuel consumption and drivability.

The U-Connect – Power Plug is fitted by the tuners with genuine manufacturers (OEM) ECU connectors specific to the vehicle model, so you simply unplug the vehicles wiring harness from the ECU, plug the vehicles harness into the PowerPlug and plug the PowerPlug 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 – PowerPlug is the only unit that can be individually tuned to your vehicle live on a dynamometer.
This means that an ECU MAP specifically optimised to your vehicle can be achieved.
The U-Connect – PowerPlug is also re-programmable, so when any modifications are made to your vehicle, (i.e. Exhaust, camshaft, etc.) the PowerPlug 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 engines settings.
For additional safety these U-Connect – PowerPlugs 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 live, the fuel quantity and injection timing of over 476 individual points of the engine speed 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 vehicles power to 1/10 horsepower, and precisely monitoring these critical temperatures, pressures and smoke emissions.
