Adjusting Fuel Maps: Gran Turismo 8 To 10

Changing the fuel map in Gran Turismo is a useful strategy to improve fuel consumption in endurance races. In most Gran Turismo 7 events, you won't need to worry about fuel consumption, but in endurance races, it becomes a crucial aspect of racing. To adjust the fuel map, players must first purchase and install a Fully Customisable Computer from the Tuning Shop, which offers more control over the engine. During a race, players can then use the d-pad to cycle through the different multi-function displays until they reach the fuel settings. From there, they can adjust the fuel map, with higher numbers reducing engine output and improving fuel consumption.

How to access the fuel map menu

To access the fuel map menu in Gran Turismo, you must first ensure that fuel consumption is activated in your race settings. This can be done by creating a custom race and activating "Fuel Depletion". Once fuel consumption is activated, you can access the fuel map menu during a race by pressing right on the d-pad to cycle through the different multi-function displays (MFD) until you see the fuel settings.

On the fuel map display, you can use the left and right buttons on the d-pad to scroll through the electronic settings of your car. When you reach the Fuel Map setting, you can then use the up and down buttons on the d-pad to adjust the fuel map from 1-5 or 1-6. By default, the Fuel Map is set to Power (1). Moving the slider to the right will increase the fuel consumption rate, while moving it to the left will decrease it.

It is important to note that the fuel map menu may not be accessible in all races, and it is primarily designed for endurance races where fuel management is a crucial aspect of the racing strategy. Additionally, some players have reported issues with adjusting the fuel map, which may be due to button mapping or other technical issues.

Adjusting fuel map settings mid-race

Adjusting your fuel map settings mid-race is a useful strategy to improve fuel consumption in endurance races. Here's a step-by-step guide on how to do it:

Step 1: Check if Fuel Consumption is Active

Firstly, ensure that fuel consumption is activated in your race. Most campaign races in Gran Turismo Sport don't have fuel consumption activated, especially early on. It's only when you get to the endurance races that fuel and refuelling become a factor. However, you can create a custom race and activate "Fuel Depletion" to experience fuel consumption earlier.

Step 2: Access the Fuel Map Menu

During the race, press right on the d-pad to cycle through the different multi-function displays (MFD) until you see the fuel settings. The fuel map menu will typically show settings from 1-5 or 1-6, with 1 being the most fuel-efficient setting and the higher numbers increasing fuel consumption.

Step 3: Adjust the Fuel Map Settings

Once you have accessed the fuel map menu, you can adjust the fuel map settings by pressing up or down on the d-pad. Changing the fuel map setting will affect both your fuel consumption and engine output. A higher fuel map setting will reduce engine output and improve fuel consumption, allowing you to go further on a single tank of fuel. On the other hand, a lower setting will increase engine power but use more fuel.

Step 4: Monitor Your Fuel Consumption and Performance

After adjusting the fuel map, keep an eye on your fuel consumption and performance. The MFD will provide an estimate of how many laps you can complete on the selected fuel setting. You may need to adjust your fuel map throughout the race depending on your position, pace, and strategy.

Step 5: Experiment and Adapt

There is no one-size-fits-all setting for the fuel map. The optimal setting will depend on the race, your car, and your driving style. Experiment with different fuel map settings to find the sweet spot that balances fuel efficiency and engine performance for your specific situation. Remember that a higher fuel map setting may be advantageous when you want to delay pit stops, while a lower setting can provide a boost when you need to catch up to other drivers.

The impact of fuel maps on engine output

A fuel map is a combination of everything an ECU (engine control unit) knows about engine-running conditions. The ECU uses a numerical map or a 3D graphical map to determine the amount of fuel to be injected and the ignition timing. The X-axis of a fuel map represents the engine's RPM, and the Y-axis represents the load on the engine or the energy required by the engine to perform a task. The ECU uses the fuel map to control fuel injector pulse width, which is the amount of time an injector stays open in milliseconds.

The fuel map controls the engine's performance and can be adjusted to improve power, efficiency, and drivability across the entire RPM range. In the context of Gran Turismo, a higher fuel map setting reduces engine output and improves fuel consumption. This is particularly useful in endurance races, where fuel consumption management is crucial for success. By adjusting the fuel map setting during a race, drivers can improve their fuel efficiency and extend the number of laps they can complete.

Additionally, the fuel map allows the ECU to make constant small corrections to optimize the engine's performance. The ECU receives data from various sensors, such as the oxygen sensor, throttle position sensor, and manifold absolute pressure sensor, to calculate the required fuel injection amount and ignition timing. By interpreting this data, the ECU can adjust the air-fuel ratio, ignition timing, and other parameters to maximize engine output while minimizing fuel consumption.

In summary, fuel maps have a direct impact on engine output by controlling the fuel injection process and ignition timing. By adjusting the fuel map, drivers can optimize engine performance, improve fuel efficiency, and ensure the engine operates at its highest potential for any given load and RPM combination.

The effect of fuel maps on fuel consumption

The fuel map is the electronic fuel injection system's setting for regulating the air/fuel mix. It is created by engineers during the construction and testing of an engine. The fuel map is not a piece of paper but a set of engine computer settings.

In Gran Turismo, the fuel map can be adjusted mid-race to reduce fuel consumption. The higher the fuel map, the lower the engine output and the better the fuel consumption. This is a useful strategy for improving fuel consumption in endurance races.

In internal combustion engines, the aim is to convert the maximum amount of chemical energy into useful work. Some factors affecting fuel economy in engines are engine power, efficiency, and mixing properties. The efficiency of a diesel engine depends on the conversion rate of the chemical energy of the fuel into heat release.

The fuel consumed by a moving vehicle during a trip can be calculated by the break specific fuel consumption (BSFC), the break mean effective pressure (BMEP), and the mean piston speed. A common way of presenting these three data is through a contour plot showing lines of constant fuel consumption on a load and speed plane. This graph is referred to as the engine or performance map.

The manifold absolute pressure (MAP) sensor provides the vehicle's ECU with information about the load of the engine, or how hard the driver is pressing on the accelerator pedal. MAP sensor controllers trick the vehicle into thinking it is always driving downhill, requiring less fuel. They balance out the signals of the fueling system, maintaining engine performance and preventing the "check engine" light from coming on.

Techniques to save fuel beyond lowering the fuel mixture

While lowering the fuel mixture is one way to save fuel in Gran Turismo, there are several other techniques and driving behaviours that can help you improve your fuel efficiency. Here are some strategies to consider:

Smooth Acceleration and Braking

Gentle acceleration and smooth braking can significantly improve fuel efficiency. Sudden starts and abrupt stops increase fuel consumption and also wear out your vehicle's engine and brakes faster. By anticipating stops and driving with a steady foot, you can reduce fuel usage.

Maintain a Steady Speed

Constantly varying your speed, especially on highways or motorways, can lead to higher fuel consumption. Maintaining a consistent speed allows your vehicle's engine to operate at its most efficient level, ultimately conserving fuel.

Tyre Maintenance

Properly inflated tyres play a crucial role in fuel efficiency. Underinflated tyres create more rolling resistance, increasing fuel consumption. Regularly check your tyre pressure and keep them inflated according to the vehicle manufacturer's recommendations.

Reduce Idle Time

Leaving your engine running while stationary or waiting in traffic wastes fuel. If you anticipate being stopped for more than a minute, turn off your engine. Modern vehicles with start-stop systems can automatically turn off the engine when the car is stationary, reducing fuel consumption in city driving.

Use the Right Gear

For manual transmission vehicles, using the correct gear at the right time is essential. Shift up as soon as possible without straining the engine, and downshift when necessary to maintain engine efficiency.

Lighten the Load

Excess weight in your vehicle can increase fuel usage. Remove unnecessary items from your car, and take off roof racks or carriers when not in use. The less weight the vehicle has to move, the less fuel it will burn.

Plan Your Routes

Efficient route planning can save both time and fuel. Utilise GPS apps or navigation systems that take into account real-time traffic conditions and suggest the shortest, most fuel-efficient routes. This is especially beneficial for delivery drivers or those with multiple destinations.

Avoid Excessive Speed

Driving over the speed limit is not only dangerous, but it also increases fuel consumption. Higher speeds place greater demands on the engine and significantly increase air resistance, leading to more fuel being burned. Staying within the speed limit helps improve fuel efficiency and ensures a safer journey.
