About ALTEZZA fuel gauge

Recommended Posts

We have only confirmed and tested on up to 2001 model. It is sold as supporting up to 2001 

Unfortunately  there is no support for the fuel gauge on the later models

How long have you had the unit for? There is a hardware update that needed to be done for early released ECUs

That is a old one so if its not been back in for a service I would say that will be the cause as the hardware updates won't have been done.

HI
It hasn’t ever sent for any service before. Can I send it now? The only issue is the fuel indicator is not working as it should.

If I update firmware may it fix the issue? Or does it need a hardware upgrade?

It is likely that the upgrade will fix the issue. Its firmware but for a sub-micro that is not field upgradable.

You are welcome to send the unit in for this at any time that suit you.
