Alfa Romeo Busso plug-in adaptor engineered to replace unreliable OEM ECUs also on Fiat, Lancia and Porsche Cup engines.
The kit provides a reliable replacement for failure-prone hybrid ME7.3.1 ECUs, which commonly develop difficult-to-repair faults such as a clicking throttle body, continuously running engine cooling fans, and a flashing check engine light. Due to their obsolescence, OEM ECUs are extremely expensive and increasingly difficult to find on the used parts market.
Compatible with and can replace any of the following ECUs:
- ME7.3.1 - Alfa 3.2 V6, Alfa Twin Spark 1.6/1.8/2.0
- ME3.1 - Alfa 2.5/3.0 V6, Fiat and Lancia R5 2.0/2.4
-
MS3 and MS3.1 - Porsche Cup
Fully functional CAN bus for the Alfa Romeo 156 GTA, 147 GTA, and GT 3.2.
Integration with the original cruise control system is also possible due build-in switchboard.
For vehicles with other engine variants, the CAN protocol can be customized upon request.
For vehicles equipped with the Selespeed robotised transmission (TS, GTA, and Stilo Abarth), please contact us.
Kit features CNC-machined, anodised aluminium mounting hardware for secure installation with alternative ECU spacing. Compatible with EcuMaster Black (requires wideband sensor wiring) or EcuMaster Pro 8 (dual LSU 4.9 lambda connections). Extended lead harness allows flexible ECU relocation, typically mounted next to ABS unit or fuse box for optimal packaging. Eliminates common OEM ECU failures with proven alternative architecture and complete hardware package included.
Available options:
- Adapter only — adaptor for EcuMaster Black plus base map
- EcuMaster Black kit — adaptor, EcuMaster Black ECU, Lambda-to-DTM link loom, and wideband lambda sensor
- EcuMaster Black kit plus — includes all Black kit components plus Lambda-to-CAN module and second LSU 4.9 sensor for dual-channel capability
- EcuMaster Pro 8 kit — EcuMaster Pro 8 ECU, two Lambda-to-DTM link looms, two LSU 4.9 sensors, and adaptor prepared for Pro 8 fitment
Note: Pro 8 kit may require an additional CAN-to-USB communication tool if your tuner does not already have one.
