Biondo Racing DDI1067 Elite RPM Shift Controller 4-Gear 3000-9900 RPM

The Biondo Racing Elite RPM Switch is a sophisticated digital shift controller designed for high-performance drag racing applications. This microprocessor-controlled unit manages up to four adjustable shift points without requiring chips, allowing racers to program precise RPM-based gear changes for optimal performance. The RPM settings are adjustable in 100 RPM increments across a 3000-9900 RPM range and are retained in memory even when power is removed.

Key Features:

• Four programmable shift points with 100 RPM increment adjustments (3000-9900 RPM range)
• 40 Amp capacity shift output handles most shifters without additional relays
• Selectable shift mode for Normally Open or Normally Closed operation (air, CO2, or electric shifters)
• Auto-reset functionality eliminates manual button pressing between shifts
• Programmable shift pulse time for precise solenoid control
• Large LCD display for easy reading in race conditions
• Shift test feature allows wiring and solenoid testing with engine off
• Ignition on/off input to disable shift output when not in use
• Compatible with 4, 6, and 8 cylinder engines
• Retains all programming when powered off
• Mounting tabs for secure installation

Dimensions: Face size 4-3/8" x 3-1/4" x 3/4", overall size 5-3/8" x 3-1/4" x 3/4". This precision shift controller is essential equipment for serious drag racers seeking consistent, repeatable gear changes at exact RPM points.
