At ExcelTune, we believe in combining safety and reliability with performance. We offer dealer level service, chip tuning or remapping, and do our utmost to ensure optimum performance and risk-free driving.
The microchip in your car’s ECU (electronic control unit) contains a lookup table that informs the engine how to respond under specific conditions. For example, if you’re driving down the highway at one hundred kilometres per hour and you suddenly accelerate, the computer will detect this and request information from the chip on how it should react or respond. The chip refers to the lookup table and instructs the computer how much petrol to send to the engine.
On a factory chip, the manufacturer dictates all possible parameters. For example: how and when an automatic vehicle must shift the car into a lower gear, how to adjust the timing and, if the car has a turbocharger, how much turbo boost to provide.
When you decide to install a performance chip, the lookup table parameters are adjusted to ensure the vehicle yields the best performance in terms of fuel economy, emissions and other constraints that usually impede performance.
Engine control units are a recent addition to vehicles, having first appeared in the late 1970s. Carmakers must adhere to global performance criteria, for example, fuel injection. These factory settings can sometimes diminish a car’s performance, and some engines only perform at 60 to 70% of their actual capacity.
The ECU in modern vehicles, combined with innovative engine technology, makes it possible to control many aspects of a car’s performance, such as spark timing and fuel injection. The ECU may also control electronic throttle control (drive-by-wire), poppet valve timing, boost control (in turbocharged engines), anti-lock braking systems, the automatic transmission, speed governor (if installed), and the Electronic Stability Control system. Manufacturers design for a specific timing and this may limit performance.
However, we can easily and safely change this by adjusting the data stored on the chip.
The term chip tuning can be misleading as people often use it to describe ECU tuning, which does not involve swapping the chip. Modern ECUs can be tuned by simply updating the software interface through a standard interface such as On-Board Diagnostics. This procedure is commonly referred to as Engine Control Unit (ECU) Tuning.
ExcelTune can achieve performance optimisation by adjusting the ignition timing advance, which may result in better performance. However, to cope with advanced timing, you must run high-octane fuel to avoid pre-ignition detonation or pinging.
If there are engine, intake, or exhaust modifications to your car, these ‘plug-and-play’ adaptations alter the flow of the engine, often causing a change in the air to fuel ratio. Without re-mapping the fuel tables, some of the performance gains may not be achieved.
If your vehicle’s engine control unit is poorly tuned, it can result in diminished performance, driveability, and could even cause engine damage.
At ExcelTune, we are your tuning experts and would love to help you improve your vehicle’s performance. As your Quantum Tuning Authorised Dealer in Melbourne, we can safely remap or tune your car and guarantee we have the experience to do it correctly.
In our modern workshop, you’ll find Dyno Dynamics tools – a global leader in the manufacture of dynamometers – created right here in Australia.
With a chassis dynamometer (or ‘dyno’), our experienced mechanics can mimic various torque and speed requirements, to provide insight into the engine or chassis functioning, whether it’s a petrol- or diesel engine, 4WD, light truck or motorhome. We then compare the results to the manufacturer’s specs. This device lets us test the entire drivetrain at once by anchoring your vehicle to the floor and placing the drive wheels on rollers.
We can test and confirm the following:
This premium electronic diagnosis equipment means we don’t guess when working on your modern engine. With this innovative technology, our experienced technicians can achieve optimal and precise performance for you to enjoy your car to the max!
Let us remap or tune your vehicle when your main aim is to save fuel. To save you money, we focus on improving the low-end torque and widening the power-band as far as we can.
This increase in low-end torque will mean the engine requires less throttle input to maintain cruising speeds, whether fully loaded or on a gradient. Your vehicle will require fewer gear changes in general and be more comfortable in higher gears at slow speeds.
Add an adjustment in your driving style to make the most of the extra low-end torque and you will see an improvement in fuel consumption. This procedure is most effective on turbo-diesel engines where the savings could be as much as 20%!
We can tune any modern vehicle with an engine management system, both petrol and diesel. Do keep in mind though, that it delivers the best results on turbo- or supercharged engines. Raising the turbo boost pressure gives you considerable gain in power, especially when combined with proper ignition timing and fuelling adjustments.
