This method would allow the speed to drift up and down by about 4-5 MPH while maintaining the 54 MPH trip average. I have been monitoring the trip average by use of a Scangauge.

In Scenic, which is showing real time fuel consumption, I can see that a very light change on the right foot can change the FE by 15% (10% is easy) and change the speed by only 1-2 mph. This is a technique I do use, noticeably on the highway or whenever I'm at a too high speed to pulse & coast.

If I had a cruise control and a real time fuel consumption in Megane then I would use them to test my mods. Currently I'm using Coast Down Testing but I can see that another car or a light change in the slope can influence the deceleration. I have the feeling that the effect is higher on the FE.

PS Anyway, what ever the method used, I wish you good results. I'm often frustrated to not be able to tell by how much each mod is improving my car as I have more and more the feeling that my butt-o-meter tells me what I want to hear. Being able to reply to other people with numbers (other than consumption in daily commutes) is also important.
