GATE Pulsar D HPA Engine, TITAN II Bluetooth, Front Wired

This is the complete conversion set with the GATE Pulsar D HPA engine and TITAN II Bluetooth EXPERT for V2 gearboxes in the Front Wired version, where the power wires run forward in the replica – typically to a battery in the handguard. The set turns a V2-based AEG into an HPA replica with two solenoid valves and closed-bolt operation, controlled by GATE's optical ETU/FCU.

The advantage of buying engine and control unit together is that they are developed for each other: the TITAN II registers the nozzle position optically with every shot, so the return time is continuously adjusted – even as the magazine spring pressure changes from a full to an almost empty magazine. Everything is set up live via Bluetooth in the GATE Control Station app (GCS) on iOS, Android, Windows, macOS, watchOS and Wear OS, from trigger sensitivity and fire modes to ROF.

Pulsar D with TITAN II – key features

Pulsar D and TITAN II together:

• TITAN II Bluetooth EXPERT: Optical trigger sensor with up to 50 sensitivity steps in the first millimetre, Bluetooth 5.2 and configurable fire modes such as BINARY and BURST – functions otherwise only found on AEGs.
• Dual solenoid valve and closed bolt: Nozzle and main air are controlled separately, and the nozzle seals against the bucking before the shot. That gives consistent feeding and makes the set less sensitive to replica alignment than a single-valve engine.
• Automatic cycle synchronisation: Optical registration of the nozzle position means you don't have to fire thousands of BBs to find the right valve timing – the system calibrates the return time itself.
• AEG nozzles included: Five nozzle lengths for MP5 and M4/M16 are included, and standard AEG nozzles can also be used. Air consumption is approx. 0.7 PSI per shot at 90 PSI.
• Multi-function port: The TITAN II has a port for accessories such as a bolt catch button, magazine sensor, tracer in the hop-up chamber and electric magazine feed.

Maintenance and safety

• Installing an HPA engine requires experience: the gearbox must be emptied, the engine placed fully forward against the front wall of the gearbox, and wires and air line routed without being pinched. We are happy to fit and set it up in our workshop in Aulum, Denmark.
• Only use high-pressure air via a regulator, and keep the operating pressure within 60–140 PSI (approx. 4.1–9.7 bar) – higher pressure can damage the engine. GATE recommends, for example, PolarStar MRS, Redline SFR or Wolverine STORM as regulators.
• The TITAN II and valves are powered by a small 7.4 V battery. With Front Wired routing there must be room for the battery at the front of the replica. The air line has a 6 mm outer diameter and M5×0.8 thread in the engine. A QD fitting (US/EU) is not included and must be bought for your system.
• The Pulsar D uses AEG nozzles and must not be combined with a nozzle sleeve. GATE advises against silicone buckings with Pulsar engines, because they wear faster and change properties with temperature swings. Rubber buckings such as Maple Leaf Mr. Hop, Madbull Blue, TNT Black with nub or G&G green typically work well.
