car diagnostic tool change driver's driving habits
 

With oil price climbing, more and more people worry,
I think a lot of fuel-efficient ways, but no ideal.
Colleague told me, the biggest fuel economy is the driver's driving habits.
He recommended me to buy a ECU Chip Tunning tool.
With this tool can look fuel consumption at any time.
Both save money and environmental protection.

any ideas?

what do you think about it?

why don't you say something about it?
