Diagnostics are a critical part of making any vehicle more efficient and powerful while also maintaining its emissions control system. With our scanning, logging, and diagnostic software, VCM Scanner, dive deep into your vehicle’s performance data with customizable charts, graphs, gauges, tables, and more so you can diagnose issues and find hidden performance!


  • Scan for Diagnostic Trouble Codes (DTCs). From exhaust and vacuum leaks to misfires, VCM Scanner can scan and read powertrain DTCs when that check engine light pops up on your dash. Scan, log, and chart all your data with customizable charts, graphs, gauges, and tables to find the root cause and officially diagnose the issue.
  • Manage Vehicle Controls. Unlike the average scan tools at your local auto part stores, MPVI3 and the power of VCM Scanner can control functions like open and closed loop, fans, gear select, timing, and air-fuel ratio—without flashing your control module.
  • Utilize Special Functions1. Take advantage of special functions like throttle relearn and transmission cleaning (for select GM transmissions) and view/reset various engine and transmission adaptives so you can build the most accurate calibration.1 Use other special features like Gear/Tire Wizard, allowing you to recalibrate your speedometer after installing bigger tires or adjusting gear ratios.
  • Experience High-Speed, Standalone Data Logging Experience high-speed, standalone data logging on the dyno, track, or street with VCM Scanner and MPVI3, now standard with Pro Feature Set—removing your laptop from the equation. Speed up the process even further with access to exclusive broadcast parameters (available for most supported vehicles). Have eyes on all your vehicle data in real-time and document every log in the process.
  • Diagnostics for Emissions Compliance View emissions critical diagnostic data in VCM Scanner from your O2 sensors, PCV system, EGR system, catalytic converter, misfires, fuel imbalances (Rich/Lead Threshold), and mass air flow meter to keep your vehicle running efficiently and emission compliant.

Whether you’re an enthusiast or a professional tuner, VCM Editor is built for you. This vehicle control module editing software offers full read, edit, and write functionality with access to a multitude of complex parameters—like torque strategies, spark tables, fueling, RPM limits, and more.

With the fastest read and write times available and more defined parameters than the competition, VCM Editor delivers unparalleled control over your vehicle’s performance.


  • With VCM Editor, read most vehicle control modules’ flash memory and save it in our proprietary .HPT file structure. Once you’ve finalized your calibration, write your changes back to various control modules via your MPVI3 tool.
  • VCM Editor’s flash utility allows not just calibration reflashing and automated recovery, but entire VCM/PCM image reflashing. This means that you’re free to make any operating system or calibration level modifications and flash those to the VCM/PCM. This has many uses for the advanced enthusiast, serious tuner, or engine swap workshop, allowing complete control over the VCM/PCM software environment.
  • VCM Editor also allows for increased vehicle support for tuners, along with access to extra VCM/PCM operating system code modifications. Additionally, VCM Editor allows the option to modify a VIN, a useful feature for mail order VCM/PCMs.
