Edelbrock AVS2 650 Series Calibration Kit for 1905 & 1906 Throttle Bodies — Precision shims & hardware

The Edelbrock Calibration Kit for AVS2 650 Series (1905 & 1906) is a precision set of components designed to fine-tune your AVS2 throttle body system for correct airflow and sensor response.

This calibration kit provides the hardware and references you need to adjust the AVS2 650 Series throttle body assemblies so they operate within the intended specifications for the matched Edelbrock systems. It is intended to be used by technicians and experienced enthusiasts during installation, maintenance, or when optimizing the unit for a specific vehicle application. The kit supports accurate calibration of sensors, mechanical linkages, and flow characteristics to help the AVS2 perform as engineered.

What does this calibration kit include and why is each part important?

The kit contains the specific items required to align and validate the AVS2 650 Series throttle bodies for models 1905 and 1906. Each component helps ensure measurements and adjustments are repeatable and reliable during setup.

• Precision hardware for setting throttle stop positions and cable geometry.
• Sensors or adapters used for verifying electronic feedback where applicable.
• Reference shims and spacers to correct minor alignment and flow discrepancies.
• Documentation or calibration charts that show target values and tolerances.

How will using the calibration kit affect installation and initial setup?

Using the kit during installation saves time by giving clear, repeatable settings and reducing guesswork. It helps installers reach correct baseline adjustments so subsequent tuning can focus on vehicle-specific calibrations rather than correcting mechanical errors.

• Speeds up attaining proper throttle geometry and idle control positions.
• Reduces back-and-forth between shop and dyno by establishing correct starting points.
• Helps prevent premature troubleshooting of electronic or fuel systems tied to mechanical misalignment.

Can this kit be used for maintenance or troubleshooting?

Yes — the calibration kit is useful beyond initial fitment. It provides standard references for periodic checks and helps pinpoint whether a symptom originates from hardware misadjustment or from unrelated systems like fuel delivery or engine management.

• Use it to re-establish factory-recommended settings after service or component replacement.
• Compare current measurements against the kit’s reference values to isolate issues.
• Validate sensor outputs and mechanical ranges without guessing at tolerances.

What should a technician know before using this kit?

Familiarity with AVS2 throttle body layouts and standard shop measuring tools is required. The calibration process assumes access to the vehicle’s installation instructions and any engine management adjustments that may follow mechanical setup.

• Have basic tools: feeler gauges, calipers, and torque wrench for accurate adjustments.
• Follow vehicle-specific installation steps before final calibration checks.
• Document baseline measurements to support later tuning or warranty checks.

Who is this for? This kit is intended for performance shops, experienced home installers, and Edelbrock-savvy enthusiasts working with AVS2 650 Series throttle bodies (part numbers 1905 and 1906). It’s most valuable when combined with professional installation practices and a methodical approach to engine management tuning. If you want predictable mechanical settings and a reliable starting point for further ECU or dyno tuning, this calibration kit provides the targeted tools and references to get there.
