Parts/Change Settings Tuning Information

Set A, B, C
Configures the set (A, B or C) settings. You can store 3 sets of settings for each car. Divide these up depending on the target race. Be careful because tire settings may change automatically if you are participating in a limited race.


Exhaust and Air Cleaner: These are exhaust and air cleaner combinations that increase the air intake and exhaust efficiencies. You can choose between the 3 levels of sports, semi-racing and racing depending on the characteristics and tuning level of the car.

Racing Chip

Computer: Upgrade the program of the computer that manages your engine to get the full potential out of the engine. This is able to increase the power and torque of the car across the board by efficiently setting the ignition timing, air-fuel ratio, etc.

NA Tuning

NA Tuning: This is tuning that increases the base performance of an engine without using a turbo or supercharger. There are three different levels known as stage 1, 2 and 3. In stage 3, torque may be sacrificed in the low to medium speed range in order to push the peak power up to the limit.

Tire Type

Tire Category: Dry Tires are divided into 3 categories. In order of increasing grip, these are normal, sports and racing. Each of these categories further contains a number of different types of tires with different grip and endurance properties. There are 3 types of normal, 3 types of sports and 5 types of racing tires, and you can fit different tires to the front and rear as long as they are from the same category. Within each category, there is an inverse relationship between grip and endurance such that the tires wear more quickly as the grip of the tire increases.


Front/Rear Tires: There are a number of choices of tires with different grip and endurance properties for each category of tire.


Nitro (N20): Nitro is an abbreviation for Nitrous Oxide. Because Nitro contains approximately 33 oxygen whereas air only contains approximately 22 oxygen, more power can be extracted when petrol is mixed with nitro and combusted. Nitro is generally used by fitting a compressed liquefied tank to the car and injecting the nitro into the intake port, etc. of the engine as needed. This section lets you configure nitro settings.

Nitro Adjustment

Adjusts the concentration of nitro (Nitrous Oxide) injection. Because the tank capacity is fixed, increasing the concentration will decrease injection time. High concentration settings are needed for the quarter mile and super high speed testing, while low concentration settings are needed for endurance races.

Turbine Kit

Turbine Kit: A turbocharger is a device where the turbine is driven by the pressure of exhaust gases from the engine, with the charging produced by this turbine generating relatively high power. Although this can deliver an overwhelmingly large increase in power, the bad points are that the charging is insufficient in the low RPM range, and that the charging has a time lag. Here you can choose from 4 different turbine kits depending on your car exhaust volume and target power. Stage 1 features a relatively mild charging response, and as you proceed through the stages the power also increases. However you should be careful of the lack of torque in the low RPM range that accompanies this increase in power.


Intercooler: The intercooler is a part that cools intake gases after the temperature rises as a result of pressurization by a turbo charger or a supercharger. Because the volume of a gas decreases as the temperature decreases, you can then feed a larger amount of gas into the engine at the same inlet pressure. In this section you can mount a large capacity racing intercooler in addition to a sports intercooler.


Supercharger: A supercharger is a device that charges the engine using a compressor that is turned by the driving force of the engine itself rather than the exhaust gas pressure as in a turbocharger. In principle, there is no time lag like that of a turbocharger, and so you can get good response from the effects of the charger even from low speeds. However at high RPM there is a loss of driving force and so this is recommended more for the technical circuits than the high speed challenges.


Brakes: You can replace the normal brakes with a racing brake kit that can endure continuous braking from high speeds. This kit contains large radius rotors, highly rigid calipers and carbon metallic brake pads.

Brake Controller

Brake Balance Controller: This is a device that can adjust the balance between front and rear brakes.
Brake Balance Controller Adjustment: This adjusts how the brake balance controller is applied to the front and rear wheels. If the front is stronger, the car will tend to under steer and if the rear is stronger the car will tend to over steer.
