JEM-Sport – 2018-2023 Mustang EcoBoost 2.3L Standalone ECU

JEM-Sport – 2018-2023 Mustang EcoBoost 2.3L Standalone ECU

This is a 2018-2023 Ford Mustang PCM/ECU/ECM programmed by JEM-Sport to run standalone without PATS. This is the ECU you need when pairing with the JEM-Sport 2018+ EcoBoost Mustang Chassis/Patch Harness.

Once installed, your engine can run without the need for OEM components such as the key, dash, BCM, ABS, steering control, HVAC, and fuel control module. In high-demand cases a remanufactured ECU may be substituted — in all cases the ECU is guaranteed to function as new.

Tunable via HP Tuners, COBB (Ford Performance Accessport only — not the standard Mustang or Focus AP), and other OEM reflashing software. HP Tuners requires 2 credits for this ECU. JEM-Sport recommends HP Tuners as COBB has discontinued the Ford Performance Accessport and no longer supports it.

JEM-Sport can pre-load any tuning changes before shipping, or your tuner can make adjustments after delivery. This ECU can also be programmed to run any 2.0L or 2.3L EcoBoost engine.

Compatibility: 2018-2023 2.3L EcoBoost Mustang — pairs with JEM-Sport 2018+ Mustang Chassis/Patch Harness

Tuning: HP Tuners (recommended), COBB Ford Performance AP, and other OEM reflashing software

Note: In high-demand periods a remanufactured, fully tested ECU may be substituted
