The Technician
35
Years in the Field
Jim Ferguson, Master Technician
Jim Ferguson has spent 35 years in the field — from dealership bay technician to independent diagnostic specialist. He built Accurate Calibrations out of a single observation: most shops don’t have access to the factory-level ADAS calibration expertise their customers need.
Today, Accurate Calibrations dispatches a fully equipped calibration lab directly to collision centers, dealerships, and independent repair shops across Northeast Ohio. Every job is performed by a certified master technician, not a subcontractor.
Our documentation standard matches what OEMs require. Every vehicle leaves with a pre-scan, post-scan, calibration report, and target-position record — providing complete liability protection for your shop.

01
OEM Procedure. No Exceptions.
We follow the manufacturer’s calibration procedure exactly. No shortcuts, no approximations. If the OEM requires a dynamic drive cycle, we do it. If it requires a specific target distance, we measure it.
02
Full Documentation on Every Job.
Every vehicle we work on leaves with a pre-scan report, calibration target-position record, and post-scan verification. Your shop has complete liability protection.
03
Mobile by Design.
We bring the lab to you. No tow. No downtime. Your facility, your schedule. Our equipment fits in a van and calibrates in your bay.
04
B2B First.
We work with shops, not around them. We do not compete with you for customers. We are your specialist subcontractor, invisible to your end customer if that is what you need.
