[PERUN] ETU++ with Japanese instructions

*DEANS specifications take time to be ordered, so please contact us if you are interested.

The functions are condensed into an extremely small board, so with just this one device you can freely set pre-cocking, burst settings, active brake settings, and more!

It's incredibly cost-effective and multi-functional! It's about the size of an electric gun connector, so it can be stored anywhere. It's smaller than the original G&G ETU, so it doesn't take up much battery space!

PERUN ETU++ is a custom control board that enhances the functionality of electric guns equipped with G&G ETU.
It allows you to customize various shooting modes and perform pre-cocking, etc.
It is also smaller than the original board, dramatically improving battery storage capacity.

■ What is PERUN ETU++ ?<br>This product is a custom circuit board designed to further enhance the functionality of electric guns equipped with G&G ETU.
By replacing it with the genuine G&G ETU control board module, the following functions become available.

-Fire mode change including 2-5 round burst -5-level active brake -8-level pre-cocking -Binary shot -5-level fire cycle suppression -5-level DMR mode -Lipo alarm

Each function can be set independently to either the SEMI or AUTO position of the selector.
In addition, it is significantly smaller than the original ETU board, and the inclusion of an electronic fuse makes it possible to make the overall wiring layout smaller.

Installation of this product does not require disassembly of the gearbox, which gives it the advantage of being relatively easy to install among electronically controlled products with pre-cocking control.
Due to the above characteristics, this product is not compatible with any electric guns other than those equipped with G&G ETU.

In case you forget the settings, the unit is also equipped with a factory reset function, allowing you to reset the settings from scratch.

■ Models that can be installed <br>This product is designed exclusively for electric guns equipped with G&G ETU (including G2).
It is not compatible with G&G models that do not have an ETU, or electric guns made by other companies that have an ETU.
Please note that this is not compatible with semi-auto models as it requires a selector to set up.

Compatible models: Only models equipped with G&G ETU.

• CM16 Series
• ARP Series
• GC16 Series
• MBR Series
• KAC SR Series (SR-25 requires selector modification)
• SBR8 Series
• ARP9 3.0 series (LM9/FAR9) (Conversion connector and wiring processing required)
• SSG-1 Series (Wiring processing required)
• TGM (MP5) series
• F2000 Series
• (GR14) M14 series
• L85 Series (Please read the notes below)
• RK74 / PRK9 series

For models with pistons that use resin teeth, such as the products below, we recommend replacing them with pistons with all-metal teeth.

• CM16 Series
• CM16 ARP 9 / ARP 556 2.0 / Raider 2.0E series
• GR14 (M14) series
• CMF-16 Series

■ Applicable conditions <br>The applicable conditions for this product are as follows.
<Allowable voltage>
・7 to 17V

<Compatible battery>
・Li-Po: 2 to 4 cells (7.4V to 14.8V)
・Li-Fe: 3 to 4 cells (9.9V to 13.2V)
・Ni-MH/Ni-Cd: 8 to 10 cells (9.6V to 12V)

<Operation cycle>
・Up to 50 shots per second

■ Note : The voltages listed in the applicable conditions are merely the allowable values ​​of the board, and it is assumed that the electric gun into which it is installed will operate mechanically without any problems at the voltage used.

This product is equipped with the latest electronic fuse, which has a much faster response speed than a physical fuse, but there is a risk of the board itself being damaged by extreme overcurrent, reverse power connection, fatal short circuit, etc. This will not be covered by the warranty, so please be careful when setting up your electric gun, checking the polarity of the power supply, and pinching the wiring.

-The G&G L85 comes standard with pre-cocking, and when the piston stops moving backward (pre-cocking), the linked bolt cover is disconnected and closes.
When setting pre-cocking using "PERUN ETU++", the piston stopping position will be forward or backward from the position when using the standard ETU board, so the bolt cover will be in an open position while setting pre-cocking.
The PERUN ETU++ has a function that allows you to release the pre-cocking by pulling the trigger for a long time, but if you do not omit blowback, you will not be able to release the pre-cocking.

・Installing this product will void the 90-day warranty from G&G JAPAN. Installation is at your own risk.
PERUN JAPAN does not guarantee any problems that may arise from installing this product.

- The retailer will not handle any problems with this product alone, so please contact PERUN JAPAN directly.

PERUN ETU++ Features

In PERUN ETU++, the following functions can be set independently for both SEMI and AUTO positions on the selector.

■Firing Mode
You can freely set the shooting modes to safety, semi, 2-5 round burst, and full.
With burst fire, pulling the trigger once will always fire the specified number of bullets.

■ Active Brake (AB)
This is an electric brake that uses the inertia force to stop the motor.
Normally, even if the power to the motor is cut off when shooting stops, the gears will continue to rotate to a certain extent due to inertia, but by applying the active brake, it is possible to prevent the gears from spinning freely due to inertia when shooting stops.
Using the active brake improves the shooting feel and makes the firing feel more crisp. It also stops the piston more accurately in situations where a semi-auto would normally double fire (overrun) at high response speeds.

■ Pre-cocking
By keeping the piston in the retracted position, the semi-automatic response is improved.
The firing cycle of a normal electric gun is that when you pull the trigger, the piston is cocked and then the BB bullet is fired. Because of this mechanism, the trigger response speed (the time from pulling the trigger to actually firing) of a typical electric gun is inevitably a little behind that of an air-cocking gun or gas blowback gun.
However, by using the pre-cocking function, the gun can be kept in a cocked state at all times, and firing can be performed immediately by pulling the trigger.
It will be possible to achieve trigger response speeds equal to or faster than those of air-cocking guns and gas blowback guns.
When the pre-cocking function is enabled, the cocked piston can be released by holding the trigger for more than two seconds.

■BINARY TRIGGER
One shot is fired when the trigger is pulled and one when it is released.
This feature is only active in semi-automatic fire.

■RoF Reduction
Suppresses the firing cycle during burst and full auto.
If your electric gun cycles too fast and causes problems, you can use this function to keep it at an appropriate cycle.
In PERUN ETU++ this setting does not affect the first shot in semi-auto, burst or full-auto.
It allows you to suppress the firing cycle without reducing the first shot response.

DMR Mode
Sets the delay time to prevent repeated trigger operations.
Like a sniper rifle, this function can be used to simulate situations where you need to fire each shot carefully. You can also use this function to prevent unintentional continuous firing.
When performing delicate trigger work, if chattering on the switch interface causes the ON/OFF operation to be pressed repeatedly, resulting in burst fire, enable this function.
Enabling this feature will ignore burst and full fire mode settings and force semi-automatic fire.

■Li-Po ALARM
When using a LiPo battery, a beep will sound to notify you of a drop in voltage.
When the voltage drops below a preset level, it will beep every 30 seconds.
This product automatically detects the optimal default value depending on the number of cells in the connected LiPo battery.
Please note that this function is not an auto-cut function for LiPo batteries. If the alarm starts to sound, replace the battery as soon as possible and charge it appropriately.
Also, if you are using a battery other than a LiPo battery, please turn this function off.

■ Electronic fuse * Always ON
This is an electronic fuse that instantly detects overcurrent and cuts off the current.
When an electrical overload caused by a short circuit, piston lock, gear crash, etc. is detected, the power supply is immediately cut off to protect the circuit board.
This electronic fuse is state-of-the-art and responds much faster than a physical fuse, providing greater safety and protection for your AEG.
They cannot withstand extremely high currents or reverse polarity connections, which are most often caused by serious human error.
This function cannot be turned off as it is related to safety.
