You want to chip tune your smart? You want to get more out of your car to make it faster and more efficient? Maybe you already know the advantages and disadvantages of chip tuning.
In this guide we present this and much more. You’ll also learn how to do chip tuning yourself.
The advantages of chip tuning on your Smart
Benefit from a performance increase of up to 30% as well as a good feeling of safety by chip tuning with the Smart. If the chip tuning is done professionally, the parts certificate is also included for many Smart models. The same applies to the comprehensive engine, engine management and differential warranty.
The innovative technology of PowerControl chip tuning optimizes the engine management of your Smart and uses the existing potential. PowerControl for your Smart uses the manufacturer’s built-in tolerances without overloading the engine and powertrain. This means improved values for power, torque, emissions and fuel consumption under all conceivable driving conditions for your vehicle. This technology is compatible with particulate filters and of course approved by the technical inspection association.
Summary of all advantages
- increases the potential of your Smart
- 25% more power for your Smart
- improved emissions
- a lower fuel consumption
Chip tuning Smart – which performance enhancements are available?
Smart chip tuning is available for all models – whether diesel (Smart cdi), petrol, turbo petrol or electric. It provides higher engine power and a higher top speed to make overtaking on the motorway easier.
The most significant improvement in chip tuning in the Smart is the switch to the dual-clutch transmission, which now carries out the shifting process almost without interrupting the tractive effort.
Is chip tuning necessary for the Smart? – that’s what experience tells us
The term chip tuning probably comes from the early days when chips could not simply be flashed around and updated. With some locked ECUs the removal and exchange of chips becomes an option again. The only option in these cases was to literally replace the chip. Often these would have to be soldered and could be quite fiddly and prone to failure due to the sensitive nature of the chips.
EPROMs, which were erasable and programmable chips, could be backwashed and reinserted into the car. Chip replacements were the only way to change an auto mapping, but now with standardized diagnostic ports it’s much easier.
Recently, more and more Smarts have been equipped with on-board diagnostic ports that allow the upload of a new card.
You can also buy performance chips that you install in your Smart by yourself. These cards are often off-the-shelf and designed for a wide range of vehicles. They offer advantages over the standard, but like all generic mods, they can never compete with a custom card designed specifically for your vehicle and driving style.
In general, any tuning will be advantageous for the Smart, but the bigger gains will come from applications with turbocharging. In a NASP engine, the power gains are 10 to 20%, but in a turbo engine the power gains are about 40% for gasoline and 30% for a turbo diesel. Even a Smart that gets a relatively small performance boost from a Remap will actually be more vibrant to drive.
The maximum power gain number is only a very small part of the equation. The reaction of the motors under acceleration and their torque curve are the main reasons for chip tuning.
The disadvantages of chip tuning are the need for more regular servicing and maintenance of the vehicle. They effectively reduce the safety distances installed by the manufacturers. This compensates for the low-quality fuel or wear and tear associated with longer service intervals.
This is how you can do the engine tuning for the Smart yourself
The ECU of your Smarts is like his brain. For your car to perform at its best, you need to keep it in good condition. With every physical intervention, the data related to such an intervention is stored in the memory banks of your car’s computer. The computer uses the assigned data to determine the optimal control conditions under which the engine should work.
The control unit mixes through the tons of data arriving in the form of measured values to decide what action the engine needs to take to ensure an ideal drive. The ECU not only tells your engine what to do, but also how to do it. Thus, the ECU uses stored data to accurately diagnose the engine control. Although you have made changes to your vehicle, the ECU still receives an input of the old data stored in its memory.
Which products are available?
The input data for the control unit should refer to the situation after the modification of the imported components and parts while the modification is being made. This means that you must delete the old data from the memory, and new data related to the postmodification should be logged in the ECU memory by mapping to new readings. This is why resetting the ECU is essential for optimal performance after a change in your Smart.
Once you have made the change, you should delete any existing data in your controller’s memory. You should then enter fresh data about the conditions that occurred after the change. The controller must work with the newly entered data, as this new data reflects the true conditions after the change.
