Bulletproof 6.0L Power Stroke FICM
The Last Injector Module You’ll Ever Need
The onset of fall and winter usually ushers in a host of cold-weather problems for 6.0L Power Stroke owners. One well-documented issue that’s often masked during warmer months but surfaces when cooler weather arrives, is fuel injection control module (FICM) failure. The FICM is in charge of sending the precise, 48-volt pulse that each injector solenoid needs in order to fire its respective injector, and when one goes south, the voltage sent to fire the injectors drops. This causes hard starts, poor cold-engine idling, lack of performance, and a decrease in fuel economy. Weak or dying batteries, as well as the 6G alternators found on ’03 to ’07 Super Dutys, are to blame for most FICM failures.
Going a step beyond the external causes of FICM failure, the folks at Bullet Proof Diesel took a closer look at the unit’s internal weak points and came up with a host of improvements. First, the power supply side of the FICM was completely redesigned and fitted with an upgraded circuit board that features much better heat transfer capability. High-quality, military-grade electrical components replace the factory, failure-prone pieces. A billet, anodized-aluminum case with added fins is utilized to better dissipate heat. To further increase durability, Bullet Proof also created the six-phase FICM, which offers two extra phases over its standard four-phase unit. The extra phases share the workload, so the circuits are never overworked. Read on to see our experience with one of the company’s six-phase FICMs.
