Do you accept speedometer / tire & gear recalibration modules from District of Columbia?
Yes — we receive modules from Washington DC and the rest of District of Columbia regularly. With about 0.3 million registered vehicles statewide, European luxury (BMW, Mercedes, Audi) are the bulk of what we see from District of Columbia.
Is there a speedometer / tire & gear recalibration shop in Washington DC I should use instead?
Most Washington DC 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 District of Columbia vehicle inspection or emissions testing affect this service?
The District of Columbia requires a biennial safety and emissions inspection for registered vehicles through the DMV. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all District of Columbia and federal requirements.
Will this fix my transmission hunting after a re-gear?
Often, yes — when the ECM still thinks the vehicle has the old gears, speed-based shift points land in the wrong place and the transmission can hunt. Correcting the axle ratio in the calibration fixes the shift-point math. It does not repair mechanical transmission wear or torque-converter faults.
Is this an odometer rollback service?
No. This corrects the calibration so the speedometer and odometer reflect the vehicle's actual tire size and axle ratio. It is not an odometer-rollback or mileage-alteration service and will never be used to misrepresent recorded mileage.
