How does Unichip increase engine power? [FONT=Arial,Helvetica]Every engine requires optimum ignition timing and air fuel ratio at all RPM and load conditions. unichip gives the experienced Dynamometer technician the access to and ability to adjust and optimize both the ignition and fuel system. Unichip has 17 RPM sites between 500 RPM and 8000 RPM and 12 load sites between zero throttle position and wide-open throttle position. This equates to 204 possible adjustments for fuel and a further 204 adjustments for ignition timing.[/FONT] [FONT=Arial,Helvetica]How much extra power can I expect from Unichip?[/FONT] [FONT=Arial,Helvetica]Power gains of 10 KW to 30 KW are common place, as measured by an accurate chassis dynamometer. Whilst less common, power gains of 50 KW have been verified. The exact power gain however depends on the design and condition of the engine and the factory calibration of the engine control unit. No two engines are identical. The Unichip results represent the optimization of each individual engine. Unichip results are verified by before and after dynamometer tests measured at 100% throttle opening across the entire RPM range.[/FONT] [FONT=Arial,Helvetica]Will Unichip improve my car's fuel economy?[/FONT] [FONT=Arial,Helvetica]Yes. In most driving conditions, Unichip will improve fuel economy. Many modern fuel injected engines waste fuel by running very rich air fuel ratios at part throttle openings. With Unichip, it is a simple procedure to correctly adjust the air fuel ratio over 12 throttle positions and maximize the fuel economy for cruising at part throttle.[/FONT] [FONT=Arial,Helvetica]How is Unichip different from "performance chips"?[/FONT] [FONT=Arial,Helvetica]Unichip is a supplementary engine management systems. As such, it is far more advanced than "generic plug-in performance chip" products. It is individually programmable to meet the requirements of engine and driver. Being fully adjustable, Unichip can cater for non-standard, current and future engine modifications. Best of all, unichip can deliver the most personalized power result every time - uniquely tuned for fuel type and rating, and even particular ambient conditions of operation.[/FONT] [FONT=Arial,Helvetica]What are the engine management advantages of Unichip?[/FONT] [FONT=Arial,Helvetica]Unlike many other engine management systems, Unichip does not alter the cold start, knock sensors, water temperature sensors, air temperature sensors or oxygen sensors. All remain genuine components. A major advantage of Unichip is that it works in harmony with the factory ECU to enhance and unleash the best possible performance result without compromising engine durability.[/FONT] [FONT=Arial,Helvetica]Is the original factory engine control unit modified by installing Unichip?[/FONT] [FONT=Arial,Helvetica]No. Unichip is a supplementary computer which is programmed to contain the optimum fuel and ignition adjustments for each individual engine. the factory engine management control unit is not altered in any way. The Unichip is simply installed by connecting to the wires of the original factory ECU.[/FONT] [FONT=Arial,Helvetica]Unichip real-time tuning - What does this mean?[/FONT] [FONT=Arial,Helvetica]Real time tuning describes the process whereby adjustments are made to the ignition timing and air fuel ratio whilst running the vehicle on a dynamometer. In doing so, the technician can optimize power output at any RPM point. For example, if we run the vehicle at 2,000 RPM, we can increase the ignition timing to the point of maximum power before reaching combustion detonation. The same practise applies to the air fuel ratio. We can clearly see, by watching the dynamometer power graph, what air fuel ratio produces the highest power at 2,000 RPM.[/FONT] [FONT=Arial,Helvetica]Is it safe to tune my car on a Dynamometer?[/FONT] [FONT=Arial,Helvetica]Yes, it is safe. A dynamometer does not create any greater load on the engine than what you experience in normal driving conditions. Very efficient cooling fans are utilized to ensure safe engine temperature control.[/FONT] [FONT=Arial,Helvetica]Does the Unichip need to be serviced or retuned?[/FONT] [FONT=Arial,Helvetica]There is no need to readjust the Unichip unless the engine has been modified. It is nearly impossible for the Unichip data to change after the Unichip ECU has been programmed, causing the engine to be detuned. It is possible however for the fuel pressure to drop (if the fuel pump deteriorates) which would cause the engine to run a leaner air fuel ratio than normal. Other items such as fuel injectors and spark plugs will need servicing from time to time which will also change the state of engine tune.[/FONT] [FONT=Arial,Helvetica]Should I use unleaded or premium unleaded fuel with unichip.[/FONT] [FONT=Arial,Helvetica]Your engine should always be tuned using the fuel which you intend to use day to day. Premium unleaded fuel will always produce the best power result, as it will allow the engine to use all of the ignition timing in the timing map. As most modern EFI engines utilize knock sensors, if you change from premium unleaded to standard unleaded, the engine's knock sensors will detect detonation and reduce timing accordingly, resulting in a loss of power.[/FONT]
