ECU identification

Moto Guzzi Quota 1000 and Quota 1100 ES models


// //

There have been two ECUs Electronic Control Unit) used on the Quota 1100 ES. The early version was supposed to be replaced or upgraded on all models. The first version had a nasty flat spot between 3,000 and 4,000 RPM. How can you determine which version you have?

  1. Remove the left side cover.
  2. Look for a finned aluminum module about 4 inch square immediately to the left of the fuses and relays.
  3. There should be a sticker on the box that says Moto Guzzi Quota 1100.
  4. The sticker should also list a number. If the number ends in i or 01, then you have the later ECU. It is also likely that your ECU has been updated if there is a sticker on top of the original Magneti Marelli sticker, or if your ECU is labeled for an entirely different model. In typical Moto Guzzi fashion, documentation is varied and more than a little haphazard.
