ECU Maps

The following information comes from : [1]

Aston Martin v12 GT3 & Aston Martin v8 GT3 (EVO)

Level	Description
Dry Maps
1	Fastest high fuel consumption
2	A bit slower, normal fuel consumption, aggressive throttle map
3	A bit slower, normal fuel consumption progressive throttle map
4	Slowest, less fuel consumption, progressive throttle map
Wet Maps
5	Similar to dry 2 & 3 map, normal fuel consumption with slightly progressive throttle map
6	A bit slower, less fuel consumption and progressive wet throttle map
7	Identical to 6 with more progressive throttle map
Pace Car Map
8	Very slow map and low consumption for Pace Car situations

Audi R8 GT3 & Audi R8 GT3 EVO

Level	Description
Dry Maps
1	Fastest high fuel consumption
2 & 3	A bit slower, normal fuel consumption 2 different throttle maps
4	Slowest, less fuel consumption, same throttle map as level 3
Wet Maps
5	Fast map, normal fuel consumption with slightly wet throttle map
6 & 7	A bit slower map with less fuel consumption and 2 different wet throttle maps
Pace Car Map
8	Very slow map and low consumption for Pace Car situations

Bentley 2016 & Bentley 2018

Level	Description

BMW M6

Level	Description
Dry Maps
1	Fastest very high fuel consumption, aggressive throttle map
2 & 3	A bit slower, normal fuel consumption, 1 linear throttle map, 1 gradual throttle map
4	Reserve engineers map, don't use. Very low power
Pace Car Map
5	Very slow map and low consumption for Pace Car situations
Wet Maps
6	Fastest high fuel consumption, wet throttle map
7 & 8	A bit slower, normal fuel consumption, 2 different wet throttle map

Ferrari 488 GT3

Level	Description
Dry Maps
1	Fastest normal fuel consumption
2	A bit slower, less fuel consumption
3	A bit slower, normal fuel consumption
4	Slowest, lowest fuel consumption
Wet Maps
5	Fastest normal fuel consumption, wet throttle map (less linear more gradual)
6	A bit slower, less fuel consumption, wet throttle map (less linear more gradual)
7	A bit slower, normal fuel consumption, wet throttle map (less linear more gradual)
8	Slowest, lowest fuel consumption, wet throttle map (less linear more gradual)
Pace Car Map
9 -> 12	Reserved and Pace Car levels. Very low power maps and low consumption for Pace Car situations

Ferrari 488 GT3 EVO

Level	Description
Dry Maps
1	Fastest extremely aggressive throttle and power delivery, high fuel consumption
2	A hint slower, still very aggressive throttle and high fuel consumption
3	Normal, aggressive throttle and normal fuel consumption
4	Normal, moderately aggressive throttle slightly less consumption
5	Normal, almost linear throttle, slightly less consumption
Wet Maps
6	A bit slower, less fuel consumption, wet throttle map (less linear more gradual)
7	A bit slower, normal fuel consumption, wet throttle map (less linear more gradual)
8	Slowest, lowest fuel consumption, wet throttle map (less linear more gradual)
Pace Car Map
9 -> 12	Reserved and Pace Car levels. Very low power maps and low consumption for Pace Car situations
