Why Oklahoma customers mail in duramax lb7 / lly ficm repair

Oklahoma has roughly 3.6 million registered vehicles, and full-size pickups & SUVs make up much of what Oklahoma City-area shops and owners mail us. Domestic work like duramax lb7 / lly ficm repair runs high-volume across Oklahoma — we see a steady stream out of Oklahoma City, Tulsa, Norman. Neighboring state — typically 1 day each way, the fastest non-Texas round-trip.

What we see from the South

Sustained underhood heat is the dominant stress on southern trucks, and heat is cumulative: it does not usually fail a board outright, it ages the joints and the power-supply components until a fault appears warm and disappears cold. If your truck starts fine at dawn and acts up at noon, say so when you ship — that pattern points somewhere specific on the board.

How long does shipping take from Oklahoma to your Arlington TX workshop?

Do you accept duramax lb7 / lly ficm repair modules from Oklahoma?
Yes — we receive modules from Oklahoma City, Tulsa, Norman, Broken Arrow and the rest of Oklahoma regularly. With about 3.6 million registered vehicles statewide, full-size pickups & SUVs are the bulk of what we see from Oklahoma.
Is there a duramax lb7 / lly ficm repair shop in Oklahoma City I should use instead?
Most Oklahoma City shops don't keep the bench equipment for duramax lb7 / lly ficm repair — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Neighboring state — typically 1 day each way, the fastest non-Texas round-trip.
Does Oklahoma vehicle inspection or emissions testing affect this service?
Oklahoma has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Oklahoma and federal requirements.
How do I know whether it is the FICM or an injector?
The pattern is the best clue you have before anything comes off the truck. One cylinder that is consistently dead usually points at that injector or its wiring. A whole bank dropping out, or a miss that appears only once the engine bay is hot, points at the driver side — the module. Balance-rate data helps a lot, and so does whether the fault ever clears on its own. Text us the codes and what you are seeing before you order; we would rather talk you out of a shipment than take money for the wrong repair.
Does my truck even have a separate FICM?
LB7 (2001-2004) and LLY (2004.5-2005) trucks do. From the LBZ onward GM moved the injector drivers inside the ECM, so those trucks do not have a separate FICM to repair — an injector-driver fault there is an ECM job. The 2006 model year is the one to be careful with, because early builds are LLY and later builds are LBZ. Send us your VIN and we will tell you which one you have.
