Unichip + Power Plug Frequently asked Questions:

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. Contact the SAC Branch near you about a Power Plug for your vehicle
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.  More questions? Contact the Expert at the SAC branch near you.
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.

Why the stage 1 conversion is still the best bang per buck.

The electronic tuning of diesel and petrol engines compare in that only the fuel amount and point of ignition are being altered.
The ignition point is determined by the spark plug firing instant in a petrol engine and the point of fuel injection in a diesel engine.
To ensure engine safety, the amount of fuel injected at any particular time is crucial. Too little fuel for a petrol engine and conversely too much for a diesel engine can lead to problems.

In terms of fuel quantity, the optimum power output for a petrol engine always corresponds to a safe fuel amount, however for a diesel engine the optimum power output occurs well beyond the engines safety point.

· Where do improvements come from?
When manufacturers develop their ECU’s they must make compromises that take into account the production and operating variations of the vehicle.
No two vehicles are exactly the same due to production tolerances and depending on where and how the vehicles are used they may experience different climatic conditions, fuel quality, service intervals, driving styles etc.

Taking all these factors into account results in a manufacturers pre-set MAP which isn’t optimum for the region of use.

If you have any questions related to Power Plug improvements for your vehicle, contact the Expert at the SAC Branch near you.

· What adjustment is being made?
These are less complex than you may have been led to believe. The simple fact is a diesel engine only needs air and fuel to operate.
Given that the air consumption of the engine is governed by mechanical factors i.e. Cylinder head and manifold design, the only adjustments that can be made electronically by chiping are the amount of fuel injected and the point at which fuel is injected.

Unichip vs other performance chips

When comparing a Uni-Chip (tuned by SAC) based product i.e. Plug & Plays, it is important to know that you get what you pay for. In the illustrations hereunder it is clear that the Uni-Chip (tuned by SAC) is by far the more superior tuning product – tool. We cannot therefore talk price or compare prices and neglect to identify the benefits or advantages of an (SAC tuned) Uni-Chip vs the rest. If you use the chart hereunder and you have a product that you would like to compare, check which boxes it ticks and do the comparison this way.

Show me some performance figures.

If we talk results, gains and claims, SAC has always maintained that reliable power needs to be achieved. The only way to truly know whether or not you have achieved reliable power is by way of measurement with state of the art correct equipment on a chassis dynamometer. Turbo charged diesel or petrol vehicles can easily have power gains that render the engine unreliable or overstressed, not to mention – unpleasant to drive.

The ultimate result is “once removed” no footprint or trace of the original installation at all. Unlike other systems there is no tampering with the vehicles’ ECU or wiring.
The Plug ‘n Play System has evolved over the past 15 years to become a universal tuning tool that can be simply plugged in via a specially made harness that requires no cutting and soldering of wires to the OEM equipment with world class adaptability and functionality.
Most modern vehicles are electronically controlled.
The Electronic Control Units (ECU) have been developed to suit World Markets, and have certain tolerances.
The U-Connect – Power Plug is a highly developed, re-programmable piggyback microcomputer which works in conjunction with the Engine Management System (EMS), already fitted to most modern engine vehicles, in order that improvements in engine efficiency, power and fuel consumption can be realized.
The U-Connect – Power Plug is capable of interacting with your vehicle’s ECU to optimize the air / fuel mixture, timing, boost and injector pressures, under various loads and driving conditions.
If you are not tuning your vehicle with a Plug ‘n Play System, you are not unleashing the full potential of your vehicle nor making use of the wide range of performance options this powerful tuning tool allows you in being number one on the drag strip or simply having a more drivable car that uses less fuel on the journey to work and back each day.
The U-Connect – Plug ‘n Play System has been programmed specifically to enhance your vehicle’s performance under tough conditions, taking into consideration all relevant factors.
SAC, the performance tuning specialists, are able to offer extraordinary levels of expertise in Unichip serial port tuning, conversions, modifications & upgrades with guaranteed results.
