JeffTron SCYLLA Airsoft Drop-In Programmable HPA ETU Module
(Model: V2)

Features

• Optical + Magnetic Sensors: Provides high trigger sensitivity, fast response, and improved durability
• Wireless Smartphone Programming: Configure settings through the iOS/Android app with real-time changes
• Wide HPA Compatibility: Supports PolarStar F1, F2, JACK, Wolverine Inferno Gen 2, and other 5V single- or dual-solenoid systems
• Adjustable Fire Modes: Supports Safe, Semi, Binary, Burst, Burst/Full-Auto, and Full-Auto modes
• Advanced Solenoid Control: Independently adjust poppet dwell, nozzle dwell, return-to-battery, ROF, and anti-stiction settings for Semi and Auto
• Rate-of-Fire Control: Adds adjustable delays between shots to reduce cadence and create a more realistic firing rate
• Adjustable Trigger Sensitivity: Magnetic trigger adapter allows precise sensitivity adjustment directly through the app
• External Accessory Output: Provides an output for accessories such as BB illumination systems, with configurable activation modes
• Detailed Performance Statistics: Tracks shot count, cycle times, processor temperature, operating time, ROF, and battery voltage
• Technical Lock Function: Helps prevent unauthorized or accidental changes to selected settings and can enforce battery-voltage limits
• Low Power Consumption & Protection: Uses approximately 1.5 mA when not actively operating and features a lacquer coating for added water-damage protection

FIRE MODES:

This feature allows you to configure firing modes and assign the mode to the position of the firing switch on the weapon. The configurable firing modes available on the Scylla are:

• SAFE: No responding on the trigger pull.
• Semi: It fires single shot per trigger pull.
• Binary Trigger: It fires single shot when trigger is pulled and another single shot when is released.
• Burst: Gun shoot burst per trigger pull.
• Burst/Full: Short trigger press fires burst, long trigger press makes auto fire.
• Full: Gun makes auto fire until releasing trigger.

RATE OF FIRE REDUCTION:

Whether you need to reduce your cadence because your field has a limit you don't meet, or you want a cadence that matches a real firearm, Scylla has you covered. The motor runs at 100% speed during each shot, and a delay is applied between shots, making the rate of fire more realistic.

HPA SYSTEM:

You can choose between single solenoid, dual solenoid - close bolt and open bolt.

SOLENOIDS SETTINGS:

You can independently select the following solenoid settings for the selector in the SEMI and AUTO positions:

• Poppet dwell
• Nozzle dwell
• Return to battery
• Rate of fire
• Anti stiction timeout
• Anti stiction pulse

DELAY BETWEEN SHOTS

Adds time in which isn't possible to shoot, it simulates the delay from gun reload or recoil (range 0,1 - 4,0 seconds)

BATTERY VOLTAGE

You can easily check the current battery status in the app. We recommend to use 7,4V lipol battery. The app automatically detects the battery, or you can choose the correct battery type yourself.

EXTERNAL OUTPUT

Used for connecting custom accessories, such as a BB illumination system in the hop-up chamber. The output provides battery voltage.

• Off: The output terminal is disabled
• Motor: The output terminal is ON during firing
• Motor + Xs: The output terminal is ON during firing and remains active for the set time delay
• Always On: The output terminal is continuously active

STATISTICS

The app offers a lot of stats and indicators that allow you to get the most out of your weapon.
Among the most important are:

• Original BB counter (from original system)
• Total number of shots fired
• Semi cycle time
• Auto cycle time
• Processor temperature
• Time how long the Scylla ran
• Rate of fire
• Battery voltage

TECHNICAL LOCK

A add-on designed to prevent unauthorized use or accidental changements.
Perfect for custom builds, high-end rentals, and field techs needing absolute control over AEG operation.

• Function Locking: Lock selected features to prevent changes.
• Battery Voltage Limiting: Set a maximum voltage limit.
• Saved Technician Settings: Locked configurations are saved and can be restored by the user.
• Timestamp Logging: A time stamp is created when the lock is applied.

FEATURES

Easy installation into the mechabox.
Wrapped in lacquer to protect the device against water damage.
You can use a mechanical trigger stop with the Scylla, however it does not have to be used.
