Part 34

Master your car's performance! This guide breaks down the optimal settings for Aerodynamics, Tires, Brakes, ECU, Turbo, and Suspension in Need for Speed Underground 2.

Alright, let's get your ride dialed in for Part 34. This isn't about a specific race, but about fine-tuning your car's performance parts to dominate on the track. We'll go through each section, explaining what the numbers mean and what you should aim for.

Aerodynamics

For aerodynamics, you want both front and rear downforce set strong. While these settings won't affect your dyno run, they're crucial for keeping your car planted during races, especially at high speeds. Aim for the maximum values here.

Front Downforce	9.98
Rear Downforce	10.00

Tires and Brakes

Grip is king! Max out both front and rear tire grip. As for the brakes, the guide suggests you shouldn't really be using them much. This implies you should focus on smooth acceleration and cornering rather than heavy braking. The Brake Bias can be adjusted, but with max grip, you might not need to touch it much.

Front Tire Grip	10.00
Rear Tire Grip	10.00
Brake Bias	-0.50 - 0.50

ECU

The ECU tuning is all about getting that torque where you need it – in the higher RPM range, starting around 4000-5000 RPM. The numbers here represent tuning stages, and you'll want to push them higher as you progress through the stages to maximize that high-RPM power.

0-1	130-135
1-2	140-145
2-3	150-155
3-4	160-165
4-5	180-185
5-6	180-185
6-7	Maximum
7-8	Maximum
8-9	Maximum

Turbo

Similar to the ECU, the turbo settings are designed to give you a significant torque boost at high RPMs. You'll see 'Nothing' for the initial stages, meaning no boost there, but then the values ramp up considerably. Aim for the higher end of these ranges, especially from stage 3.1 onwards, to get that explosive acceleration when you need it.

0-1	Nothing
1-2	Nothing
2-3.1	10-15
3.1-4.3	26-28
4.3-5.4	50-53
5.4-6.5	70
6.5-7.6	88-90
7.6-8.8	Maximum
8.8-10	78-80

Nitro

The guide mentions nitro being powerful and lasting longer, with a specific hint to press right 4 times from 0. This suggests a tuning setup that balances power with duration, likely around the 4th stage of tuning.

Suspension

For suspension, the goal is a low, stiff setup that sacrifices some comfort for better handling. You'll want to lower the car significantly, use soft springs (which might seem counterintuitive, but combined with hard shocks, it works), stiffen the shocks, and use soft sway bars. The steering ratio should be medium.

Front Lowering (in)	-1.30
Rear Lowering (in)	-1.29
Front Springs	0.00
Rear Springs	0.00
Front Shocks	10.00
Rear Shocks	10.00
Front Sway Bar	...
