If you or someone you know has been affected by a failed FICM in an LLY Duramax, you are not alone, and help is available. Circuit Board Medics has launched our very own LLY Duramax FICM. Built from the ground up, you will get OEM-level drivability backed by the reliability that Circuit Board Medics is known for. We didn't just build it and put it on our website. We have relentlessly tested it in the real world to ensure it will handle whatever you throw at it. Click the link below to get your Duramax back on the road!
