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.

has this issue been resolved? having this issue on a altezza 280t using the g4+ plugin ecu... 

What issue do you have?  Has yours been tuned in modeled mode? 

Provided your ecu is less that about 3 years old it will work correctly for models 2001 and earlier.  Some of the older ecu's may need a code update in the BEAN controller.

it is a Feb 2019 manufactured ecu, tuned using the basemap for altezza in the pclink software which I believe is a modeled fuel.

Hello, I am also late version altezza owner.

May I know what modification is required if I install altezzlink?

Will there any support from LINK if I can send my OEM ECU to LINK for investment?

If your car is later than 2001 then it is not supported.  If it is a 1998-2001 model and tuned using the modeled fuel equation then the fuel gauge should work correctly.

Hi Adamw, may I know beside the missing fuel gauge signal, any other modification is required?

Someone told me the ignition coil signal are different. But I am not sure about this info. (OE ignition coil part no. Are different on early and late version)

Having not done any testing on the later cars its a little hard to answer. 

The coils likely improved and generally this required lower dwell times.

It is really struggling on my case.

I am running my altezza with PowerFC. But after I upgraded to 2.2 toda kit. I found there is too much limitation on PowerFC setup and looking for a AltezzaLINK.

Do you have suggestions on my case? CAN I send.my OE ecu to LINK and defined a solution on my case?

Link would need a complete car to test, not just the ecu.  Given the low popularity of the model and the complex BEAN communication I suspect it would not be economical for Link to look at reverse engineering a later model when there is little demand.
