Fuel Meter Precision

[ecarruda]

Hi Guys,

I'm from Brazil and i have Volkswagen Jetta MK5 2.5 (20v 5cc) 2010, this car has all electronics from MK6 version...

I have a problem about precision o Fuel Meter Gauge, i replace my Fuel sensor by OEM sensor ( now we know about precision of this sensor ), i have 3 different problems about precision display:

1. When I refill fuel tank ( stop on automatic stop of bomb ) it takes some time (days) to exit the maximum indicator
2.<=50% speed is incremented very high.
3. ON 0 position i have 1 - 2 L of fuel on tank

How i can change precision of this? I need to change scale or fuel meter curve? Some one did it or know how do it?

I can attach eeprom dump file if someone want to see OEM configuration.

Thanks!

Is it an approach to do it?
