Controller Specifications

COMPUSHIFT II

System Design

• High-speed microcontroller running COMPUSHIFT II software
• Software-preprogrammed shift and pressure tables, proprietary shift algorithms, built-in diagnostics and display software
• Nonvolatile memory for storage of calibration and programming information
• High-density multilayer surface-mount printed circuit board
• Factory- and field-upgradeable

Programming

• Factory programmed with all necessary software
• Adjustments, setup and calibration via handheld display or PC setup utility
• No PC or laptop computer required to completely program COMPUSHIFT II

Chassis

• Chassis is a factory-sealed black powder-coated aluminum box with mounting flanges. There are no user-serviceable parts inside. The chassis should not be opened.
• Dimensions
  • 4.875 x 6.375 x 2.125″ (excluding mounting flanges)
• Mounting Flange Dimensions
  • 0.625 x 6.375″ (two flanges, opposite ends)
• Mounting Holes
  • 2 – #10 holes per flange

Mounting Requirements

• Controller must be mounted in a dry area, not exposed to heat from the exhaust, cooling, or heating systems
• Controller must have clear air circulation (a 1″ air clearance around the sides and top is recommended)

Environmental Requirements

• Relative Humidity
  • 0% – 90%, non-condensing
• Temperature (Operating)
  • -30º – 60º C (-22º – 140º F)
