Lead Technician & Founder
Jim Ferguson
Jim Ferguson has spent over 35 years diagnosing and repairing vehicles across every major system — from early OBD systems to today’s advanced driver assistance technology. His career spans independent shop work, fleet diagnostics, and the emerging ADAS calibration field.
Jim founded Accurate Calibrations & Programming to give independent repair shops access to the level of technical expertise that was previously only available at dealerships. He operates as a mobile and remote service provider, traveling to shops throughout Northeast Ohio and offering remote diagnostic and programming support nationwide.
Every job is documented, every procedure follows OEM specifications, and every calibration is verified before the vehicle leaves service. Jim’s approach is technical first — no shortcuts, no guesswork, no returns.
