This is a good used Bosch Electronic Control Unit (ECU) for 1500 cc 1984-88 Fiat and Bertone X1/9s with fuel injection. Bosch part number 0 280 000 223.  This ECU can be used in place of earlier blue or orange sticker ECUs, but you will need an altitude sensor (not included). 

This part is used, but guaranteed to work fine.

For reference, three part number ECUs were used in these cars:

0 280 000 191 blue sticker and blue dot, 1980-83, without altitude sensor

0 280 000 208 orange sticker, 1980-83, without altitude sensor, direct replacement for above

0 280 000 223 gold sticker and gold dot, 1984-88, with altitude sensor

Will be shipped via USPS priority mail.  See my other Fiat part listings and save on combined shipping.
