Do you accept speedometer / tire & gear recalibration modules from North Carolina?
Yes — we receive modules from Charlotte, Raleigh, Greensboro, Durham and the rest of North Carolina regularly. With about 8.4 million registered vehicles statewide, trucks, SUVs & imports are the bulk of what we see from North Carolina.
Is there a speedometer / tire & gear recalibration shop in Charlotte I should use instead?
Most Charlotte shops don't keep the bench equipment for speedometer / tire & gear recalibration — 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. Cross-region southeast — about 2-3 days each way.
Does North Carolina vehicle inspection or emissions testing affect this service?
North Carolina requires an annual safety inspection statewide, with OBD-II emissions testing in a set of more populous counties. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all North Carolina and federal requirements.
Can the speedometer be recalibrated on the bench by mail?
On supported, unlocked GM ECMs (primarily E38, E67, and E92), yes — we rewrite the tire-size and axle-ratio values in the calibration on the bench so the speedometer, odometer, and shift points read true. Support depends on the controller, operating system, and calibration, which we verify by VIN and module label before accepting the order.
My vehicle isn't a GM — can you still do it?
Sometimes. Bench recalibration only works on controllers that are unlocked and bench-readable. Many non-GM vehicles, newer locked controllers, and cluster-based systems must be recalibrated at the car over OBD and cannot be done by mail. Send us your VIN and module label and we will tell you up front whether yours is a bench job before you ship.
