Renault Logan 1.6

I purchased a unit for my 2009 Renault Logan 1.6 which I fitted to the vehicle (little bit worried that it would work) but I’m pleased to report that it DOES work.
I am not the lightest foot when it comes to driving so I was surprised when my consumption changed from 8/9 km per litre (town driving) to a fantastic 13/14 km pre litre. CAN’T wait to get on the open road for a long trip!!!
Such a small adjustment for quite a difference.
Do you have a unit to fit a 2006 Ford Bantam?
Once again thank you
