ACC Strategist - My free Android app (+ web app) to easily calculate fuel and strategies


Based on various easily editable parameters, this app provides you the best strategy without fuel saving, as well as all the different strategies possible with up to 20% of fuel saving.

This app is 100% free and doesn't have any ads.


- Default lap times for each track, changes are saved. A reset to default button is available.

- Default fuel usage for each track-car combo (default values given by the game in Setup menu), changes are saved. A reset to default button is available.

- Multiple strategies are calculated, based on the race length, formation lap, pit stop rules, max stint duration, average lap time, fuel usage, tank capacity and time lost in the pits, with 0 to 20% fuel saving.

- For each strategy, the app calculates the following informations:

* Number of laps

* Number of pit stops

* Lower cut-off lap time (if the average lap time is lower than this value, the race will be longer)

* Higher cut-off lap time (if the average lap time is higher than this value, the race will be shorter)

* Starting fuel

* Fuel saving (Either "No", or the percent of fuel to save in the longest stint of the race, up to 20%)

* For each stint: Number of laps and fuel usage average

* For each pit stop: Lap of the pit stop and amount of fuel to add

- How to use ACC Strategist
Just fill the form, adjust the average lap time and fuel usage if needed, and click Go!
The app will then show you a screen with all the information needed for your race.

- How does it work?
The app first calculates a base strategy, without any fuel saving.
Then, if the race has more than 1 pit stop, it will compute a strategy with 1 pit stop less, which means with fuel saving.
If this strategy is valid according to the rules and the fuel saving is under 20%, it will be shown in a separate tab.
Average lap time and cut-offs are adjusted too, to compensate the time gained by avoiding a pit stop.
Then, the app tries to reduce again the number of pit stops, until it's not valid anymore. There can be up to 6 strategies for 24h races.

- Does the app takes any margin?
No, the app doesn't take any margin, but it shows you for each stint the average fuel consumption.
If you keep your average under this value, you will be fine, as long as the average lap time was not set too slow.
If you want to take some margin, you can always add a few more liters or increase the fuel consumption.

- What are lower and higher cut-off times?
Lower cut-off is the average lap time limit where the race would be 1 lap longer, and higher cut-off the limit where the race would be 1 lap shorter.
If the average lap time is close to the lower cut-off, you might want to take a few extra liters just to be sure.

- Which engine map should I use?
Use the fastest engine map in practice and enter the fuel usage in the app.
If the race is long enough to justify a fuel saving strategy, test different maps to see how you can reach the fuel usage wanted without loosing too much time.

- How to save fuel during a race?
There are 3 different ways to save fuel: short shifting (don't rev all the way to the rev limiter, switch gear earlier), engine maps (see above) and lift'n'coast (lift the throttle earlier than the normal braking point, coast a bit, then brake later than the normal braking point).
It seams that the last one is not very effective in ACC, but short shifting and engine maps can save you a lot of fuel with minimal time lost, but it will change a lot for each track-car combo so you'll need to do some tests.

- Should I go for the fuel saving strategy?
You can see that the average lap time is different for each strategy. If, for example, the average lap time is 2:00 for the normal strategy and 2:01 for the fuel saving one,
then if you can reach the fuel usage needed without loosing more than 1s per lap, go for the fuel saving strategy, otherwise the normal one.

- What about wet races?
You can adjust the average lap time and fuel usage to match the weather conditions.
Just take a bit of margin in case the weather is getting better and lap times are getting faster again.

- Why is there not every versions of the cars?
There's a few GT3 cars that have 2 different versions in the game (normal and Evo, 2015 and 2018) but they always share the same fuel tank capacity, as well as the same default fuel usage, so you can safely use the app with any of the 2 models.

- Can I see a lap-by-lap breakdown?
Yes, just click on a stint to open a detailed view.
