Fitting Alfa Romeo ECUs to your car
Alfa Romeo engine computers depend on the engine version, power output and year, so the same car model can have different control units. The safest way is to compare every number on the label of the used ECU: the manufacturer number (for example Bosch or Siemens) and the OEM number.
Numbers and markings of Alfa Romeo control units
Among Alfa Romeo listings you will meet ECU families such as MJD. The family marking is only part of the identification, so always check the full number on the label. The Bosch number 0281032518 is sometimes written as 0 281 032 518, so search both ways. Engines in the listings here include 1.9 JTD, 1.9 JTDM, 2.4 JTD.
