Aveo local fuel economy

[Mightyspider]

Hi Wezzo,

i have a Chev Aveo LS 1.6 as well and would like to know more about the Fuel Management system upgrade.

How long does it take them to do it?
What do they do when upgrading the FMS (Fuel Management System)?
What is the cost of doing this at a GM dealership?

I live in Cape Town and my work place it quite far from where i stay, I travel to work for about 45min and the disctance from my place to work one way is about 46km so to round it off to work and back home cost me about R100 ($11.75) So if the fuel management system improves the fuel economy then ill be very intrested to upgrage my FMS.

Regards
