Spool FX-200 HPFP Upgrade | BMW B58 Gen.1

The Spool Performance FX-200 is a high-pressure fuel pump (HPFP) performance upgrade for BMW B58 Gen1 engines. This model replaces the previous FX-180 version and offers significantly increased fuel capacity for demanding tuning setups.

What is the FX-200?

The FX-200 is an upgraded HPFP with a larger piston diameter than the stock pump. This allows for approximately double the fuel flow compared to the original pump.

• Approximately 2x flow compared to stock
• Full E85 compatibility
• Plug & Play installation without cutting or wiring changes
• Enables higher fuel delivery at higher power levels

Additional capacity enables:

• Higher ethanol blends
• Larger turbochargers
• Wider tuning possibilities

Why is an upgrade necessary?

The stock HPFP of the B58 Gen1 engine is a significant limitation in tuning:

• Insufficient fuel supply for higher power
• Use of ethanol blends is limited

FX-200:

• Doubles the fuel system's flow capacity
• Significantly raises the platform's fuel limits
• Enables more efficient and safer tuning

Software Requirements

The use of the pump requires software modifications:

• Calibration must be performed before use
• Without adjustment, use may cause damage and void the warranty

Spool:

• Provides necessary calibration data to the tuner
• Assists in finding an experienced tuner if needed

Note: Spool does not provide ready-made custom tunes

Important Note: LPFP

The low-pressure fuel system is critical for HPFP operation:

• Insufficient LPFP can cause damage to the pump and injectors
• HPFP lubrication is based on fuel flow
• Lack of fuel can lead to wear and failure

Recommendation: ensure sufficient low-pressure side upgrade as part of the overall setup
