Part 36

Unlock the full potential of your ride in Need for Speed Underground 2 Part 36! Get the best suspension, drivetrain, aero, and ECU tuning for maximum performance.

Alright, let's dive into Part 36 of your Need for Speed Underground 2 journey. This section is all about fine-tuning your car's performance, specifically for the 'Street X' class. We'll be looking at suspension, drivetrain, aerodynamics, and the ECU. Pay close attention here, as these settings can make a huge difference on the track!

Street X Tuning

Suspension

For suspension, we're aiming for a setup that keeps your car planted but still responsive. Here’s what the guide recommends:

• Low Lowering: -1.30 inches in the front and -1.29 inches in the rear.
• Soft Springs: 0.00 for both front and rear.
• Hard Shocks: 10.00 for both front and rear.
• Soft Sway Bars: 0.02 in the front and 0.00 in the rear.
• Medium Steering Ratio: Set to 1.00.

This setup should give you a good balance of grip and handling.

Drivetrain

The drivetrain is crucial for how your car accelerates and reaches its top speed. The guide suggests prioritizing acceleration, as you often won't hit your absolute top speed in races. Here's the breakdown:

Gear	MPH
1st Gear	33.6
2nd Gear	52.8
3rd Gear	74.9
4th Gear	98.2
5th Gear	127.3
6th Gear	167.5
Final Drive Ratio	4.34

The recommendation is to set your gearboxes to be really sequential for even better acceleration. This means each gear will smoothly transition into the next, keeping you in the power band.

Aerodynamics

Aerodynamics help keep your car glued to the road at high speeds. For this setup, you'll want strong downforces:

Downforce	Value
Front Downforce	9.98
Rear Downforce	10.00

While these settings might not show a huge difference on the dyno, they'll definitely impact your car's stability and handling on the actual track.

Tires and Brakes

For tires and brakes, the focus is on maximum grip and control:

Component	Setting
Front Tire Grip	10.00
Rear Tire Grip	10.00
Brake Bias	0.50

Maxing out tire grip is essential for cornering, and the brake bias setting helps balance stopping power.

ECU

The ECU (Engine Control Unit) settings are about getting the most torque out of your engine, especially at higher RPMs. The guide suggests aiming for strong torque from around 4000-5000 RPM onwards. The settings are broken down into ranges:

RPM Range	Torque Value
0-1	120-125
1-2	125-130
2-3	155-160
3-4	165-170
4-5	178-180

Remember, these ranges aren't exact, but they give you a solid target for tuning your engine's power delivery.

Note on Nitro: The guide mentions Nitro but states you can't use it for this particular setup. So, don't worry about it for Part 36!
