Product Details

Circuit Board Medics offers a brand-new, custom-built FICM (Fuel Injector Control Module). A built-from-the-ground-up redesign of the factory module, it features brand-new components and modern engineering replacing the OEM FICM in your vehicle. No programming required, simply plug-and-play.

Proven Performance

We didn't just build it, we rigorously tested it. Our team recently made the drive from Greenville, SC to Indianapolis, IN towing 13,000 lbs the entire way and running our brand-new, built-from-scratch FICM head-to-head against an OEM unit. The results speak for themselves. Fuel delivery was flawless, EGTs stayed consistent, and there was zero difference in drivability between our FICM and the factory unit, a truck pulling a heavy trailer from South Carolina to Indianapolis and back without a single fueling issue. When we ran a side-by-side comparison over a 3-hour round trip test drive to Charlotte, the numbers were nearly identical across injection command, MAF, and RPM, proving our unit performs right in line with OEM standards.

At Circuit Board Medics, every product we release has earned its place on the road. We test relentlessly, we refine obsessively, and we don't call something finished until we'd stake our own truck on it.

  3. Install your FICM - Once your new FICM arrives, install it in your truck.
  4. Ship your old FICM back to us - just ship your original "core" back to us. We do not require an up front core deposit, but a core charge must be captured if a completed LLY FICM is not returned to Circuit Board Medics. 

If Circuit Board Medics does not receive your core within 15 calendar days of the ship date of your new unit, an additional core charge of $500 will be charged to your credit card. Your original FICM must meet the following qualifications:

Core Return Requirements

Your core does NOT have to be rebuildable. It MUST be a complete LLY FICM. This means returning the old part in its entirety, with no pieces missing or removed.
