AEM 30-8761 CAS Trigger Disc - Manual (Page 2)

Page 2 of 25
**Cam / Crank Angle Sensor: AEM trigger disc MUST be used
Discrepancies have been observed in the OEM cam/crank signals between model years
and/or trim levels; to avoid confusion the Series 2 EMS does not support the OEM Nissan
trigger pattern. A replacement trigger disc is now included with every Nissan EMS and
must be installed before attempting to start the engine. The following installation was
performed on a stock 300ZX. Installation in a Skyline or modified 300ZX may require
removal of different components to access the CAS sensor, but the procedure for the CAS
disc change should be identical.

(AEM P/N 35-8761, supplied with 30-6620 EMS)
