AEM V3 Standard Controller Kit - Internal MAP w/ 35psi Max

AEM V3 Standard Controller Kit with 35psi Internal MAP | PN 30-3304

Upgrade your boost setup with the AEM V3 Water/Methanol Injection Standard Controller Kit (35psi max). Features an internal MAP sensor, linear flow, and failsafe protection.

The AEM V3 Standard Water/Methanol Injection Controller Kit (Part Number: 30-3304) delivers precise progressive flow control for turbocharged and supercharged gasoline engines operating up to 35 PSI of boost. Designed around an internal onboard Manifold Absolute Pressure (MAP) sensor with an integrated barbed fitting, this controller reads manifold pressure directly to inject fluid proportionally as boost rises.

The V3 series features an optimized flow-control algorithm that yields linear fluid delivery, matching engine demand to maximize charge-air cooling and detonation resistance. Encased in a splash-resistant housing, the controller features large turn-resistant adjustment dials for setting start and full-activation pressure points, an integrated splash-proof test button, and a built-in fuse. Coupled with a color-coded, positive-lock wiring harness, it eliminates wiring errors while integrating AEM’s Boost Safe failsafe system to protect your engine under error conditions.

Best Uses

1. Boost-Dependent Forced Induction: Turbocharged or supercharged gas engines targeting up to 35 PSI of manifold pressure.
2. High-Octane Equivalent Tuning: Preventing engine knock/detonation under high boost on pump gas without running expensive race fuel.
3. Intake Charge Cooling: Reducing air intake temperatures (AITs) during track days, drag racing, or heavy towing.
4. System Upgrades or Replacement: Replacing older V2 controllers or upgrading standalone water/methanol setups with modern linear flow algorithms and positive-lock wiring.

Features

1. Integrated 35 PSI MAP Sensor: Built-in manifold pressure sensor with a molded barbed fitting eliminates the need for external voltage sensors.
2. Turn-Resistant Adjustment Knobs: Oversized, easy-to-read dials let you independently calibrate start and full-injection boost thresholds.
3. Integrated "Boost Safe" Failsafe: Monitors system continuity, shorts, low fluid levels, and voltage faults to trigger a ground output for engine protection strategies.
4. Terminated Positive-Lock Harness: Color-coded, vehicle-ready wiring harness equipped with positive-lock connectors and an integrated pump ground circuit.
5. Linear Flow Control Strategy: Updated V3 firmware scales injection output linearly relative to boost for smoother power delivery.

Benefits

1. Suppresses Detonation: Reduces air inlet temperatures significantly, preventing pre-ignition under high boost levels.
2. Unlocks Extra Power: Enables safer increases in boost pressure and advanced ignition timing for power gains of up to 20%.
3. Engine-Safe Operation: The Boost Safe failsafe feature quickly alerts or triggers limp-mode strategies before damage occurs.
4. Simplified Installation: The internal MAP sensor and pre-wired connector eliminate complex external wiring and sensor plumbing.
5. Efficient Fluid Delivery: Linear fluid mapping minimizes fluid waste while maintaining maximum cooling effect under load.
