ECU Reflash required? YES
Why do you need it?
The stock HPFP on the M176 Motors is severely limited in capacity when trying to tune and raise the output of the motor. The FX-170 adds 50% more flow to the equation, raising the fueling limits on the platform and helping you run bigger turbos and/or higher ethanol concentration blends.
Spool 10-micron filter unit
Our 10-micron filter unit boasts the best filtration available on the market without any noticeable pressure drop in the low side fuel system. The filter unit helps keep the high-pressure pump and injectors safe by protecting them against debris and is highly recommended.
OPTIONAL Spool Ethanol Content Monitor
The spool ECA kit features a digital readout of in-tank ethanol content and fuel temperature. It includes our SPOOL Ethanol content analyzer app on mobile and readouts are delivered via BLE 4.0 low energy technology. BLE4.0 allows you to use your regular Bluetooth devices on your mobile devices while being connected to the SPOOL ECA module. The ECA module also has a 0-5V filtered output for flex-fuel implementation on the M276 platform if needed. Fuel lines used in the kit are braided steel nylon core fuel lines that are 100% E85 compatible.
Are tune changes required?
The upgraded pumps do require calibration changes. It is important to apply these changes prior to starting the car with pumps installed to avoid any possible damage and void of warranty.
