Why Missouri customers mail in duramax lb7 / lly ficm repair

Missouri has roughly 5 million registered vehicles, and trucks, SUVs & imports make up much of what Kansas City-area shops and owners mail us. Domestic work like duramax lb7 / lly ficm repair runs high-volume across Missouri — we see a steady stream out of Kansas City, St. Louis, Springfield. Regional north — 1-2 days each way.

What we see from the Midwest

Salted winters plus long agricultural and towing duty cycles are the pattern we see from the Midwest. Modules on these trucks accumulate an unusual number of thermal cycles — cold soak overnight, hot underhood by mid-morning — and that is the loading that eventually opens a marginal solder joint. It is also why an intermittent fault that follows temperature is worth mentioning on your job note.

Missouri FAQ

Common questions from customers shipping from Missouri.

How long does shipping take from Missouri to your Arlington TX workshop?
USPS Priority Mail from Kansas City, MO reaches our Arlington workshop in about 1-2 business days. USPS Priority is a short run north from the North Texas network; often 1-2 days. We start work the same day your module arrives and typically ship back next business day at the return speed you chose at checkout.
How much does it cost to ship a module from Missouri?

Do you accept duramax lb7 / lly ficm repair modules from Missouri?
Yes — we receive modules from Kansas City, St. Louis, Springfield, Columbia and the rest of Missouri regularly. With about 5 million registered vehicles statewide, trucks, SUVs & imports are the bulk of what we see from Missouri.
Is there a duramax lb7 / lly ficm repair shop in Kansas City I should use instead?
Most Kansas 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. Regional north — 1-2 days each way.
Does Missouri vehicle inspection or emissions testing affect this service?
Missouri requires a safety inspection for many vehicles and emissions testing in the St. Louis metro area. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Missouri and federal requirements.
Where does the work actually happen?
At our own bench in Arlington, Texas. Auto Module Lab is a mail-in electronics lab — we do not have branches in other cities and we do not sub the work out. Modules come to Arlington from all fifty states and go back out from here.
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.
