AEM Cam Angle Sensor Disk for Nissan SR20DET RWD KA24DE (50mm OD)

AEM Cam Angle Sensor Disk (30-8760) – Nissan SR20DET RWD & KA24DE (50mm OD)

Upgrade your Nissan SR20DET RWD or KA24DE with the AEM 30-8760 50mm OD Cam Angle Sensor Disk. Essential 24+1 trigger disc for AEM and aftermarket ECUs.

The AEM 30-8760 Cam Angle Sensor (CAS) Disk is a precision-engineered trigger disc designed to replace the standard factory optical disc inside OEM Nissan distributors and Crank Angle Sensor assemblies. Factory Nissan CAS discs utilize uneven or high-resolution slot patterns that standalone engine management systems often struggle to decode accurately at high RPMs or during rapid acceleration.

Featuring a 50mm Outer Diameter (OD) and a D-shaped shaft hub, this 24+1 tooth pattern trigger disc provides an ultra-clean, rock-solid timing signal. It is required for seamless operation with AEM Programmable Engine Management Systems (EMS) and is widely supported across various popular aftermarket ECUs (such as Haltech, Link, MoTeC, and MaxxECU). By delivering clear engine position data, it eliminates misfires, timing drift, and sync losses, ensuring your engine runs reliably under high-boost and high-RPM conditions.

(Note: Always verify your OEM CAS hub shape and disc diameter prior to purchase, as Nissan used multiple CAS revisions across engine production runs).

Best Uses

1. Standalone ECU Conversions: Essential upgrade when tuning on AEM EMS or compatible standalone engine management systems.
2. High-RPM & High-Boost Builds: Recommended for high-performance Nissan SR20DET (RWD) and KA24DE engines where stable, precise ignition timing is required.
3. Misfire & Timing Drift Resolution: Ideal for resolving trigger signal issues or sync errors caused by stock Nissan optical discs.

Features

1. 24+1 Tooth Trigger Pattern: Features 24 evenly spaced teeth and 1 reference/sync tooth for clean crank and cam angle decoding.
2. Precision 50mm Outer Diameter: Designed specifically for 50mm OEM Nissan CAS housings.
3. D-Shaped Center Hole: Direct drop-in fitment for D-shaft distributor/CAS assemblies.
4. Direct Replacement Design: Installs directly into the factory distributor housing without requiring custom brackets or external sensors.
5. High Precision Stamping: Engineered to deliver crisp optical sensor edge transitions for accurate signal readings across all RPM ranges.

Benefits

1. Rock-Solid Ignition Timing: Eliminates spark scatter, timing drift, and sync loss for smooth, accurate ignition timing.
2. Enhanced Tuning Capability: Allows tuner-friendly setup and setup stability on standalone ECUs.
3. Cost-Effective Upgrade: Replaces the stock optical disc inside the factory unit, saving the cost of custom crank trigger wheel setups.
4. Improved Engine Reliability: Prevents engine knock and misfires caused by inconsistent OEM trigger signals under heavy load.
5. Plug-and-Play Fitment: Fits into original mounting locations within compatible OEM Nissan CAS units.
