S15Link NS15X

Description

The NS15X fits inside the factory enclosure and replaces the OEM ECU of SR20 engines with the 64-pin blue header plug, with no alteration to the wiring loom. E-Throttle control as standard and the new 4-pin powered CAN connector.

G4X Plug-In ECUs replace the factory ECU and fit inside the original enclosure, with no alteration to the vehicle wiring loom. All the features of a Link G4X wire-in ECU, with a direct-fit installation.

Important notes

• Before purchasing, check that your factory ECU connector matches the header shown in the photos.
• Manual transmission only.
• Onboard 7 bar MAP sensor.
• Most factory features are supported.
• E-Throttle (drive-by-wire) support included as standard.
• 4-pin powered CAN connector: use the CANJST4 cable (Link PN 101-0198) to connect CAN devices. The old CANPCB cable is not compatible. The port also provides a protected 12 V supply with a 3 A self-resetting fuse.
