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

Do you accept speedometer / tire & gear recalibration modules from Connecticut?
Yes — we receive modules from Hartford, Bridgeport, New Haven, Stamford and the rest of Connecticut regularly. With about 2.9 million registered vehicles statewide, European luxury (BMW, Mercedes, Audi) are the bulk of what we see from Connecticut.
Is there a speedometer / tire & gear recalibration shop in Hartford I should use instead?
Most Hartford 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-country northeast — about 3 days each way.
Does Connecticut vehicle inspection or emissions testing affect this service?
Connecticut requires a biennial OBD-II emissions inspection for most vehicles statewide. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Connecticut 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.
