It's good to do a speed vs. mpg chart for your car so you can track your progress over time with various mods.

From: http://ecomodder.com/forum/141036-post116.html

Blue = boat tail & taller gearing ; Orange = taller gearing; Green = original

I've taken a slightly different approach here..

I log the AVERAGE speed of my 328i per tank (usually 230-270 miles), and do tank to tank MPG comparisons..

I've plotted these in an effort to determine the best AVERAGE speed for LPG consumption.

In the chart below

Speed (MPH) is along the bottom

MPG (imperial) is up the side

The values attached to the data points are the MPG recorded at that speed

I'd be interested in your opinions and observations..

It's interesting to noodle the graph...

But I'm not sure using average speed as a measurement over an entire tank works well as feedback to the driver unless the tank is predominantly highway/rural cruising, and other tanks results are over the same/similar route. (IE - controlling for as many variables as possible.)

EG: if a tank includes a siginificant mix of city/suburban plus highway motoring, how do you interpret the results & use the average speed number to your benefit?

Also: does the measurement of average speed include time stopped? (EG: the ScanGauge average speed calculation is not a "rolling" average, which would be more useful. Its calculation includes time stopped.

Consider too that spread out through the year, weather effects will affect the MPG numbers (cold weather = worse mileage; warm = better). How is that separated from the average speed variable?

The reasoning I decided to measure tank to tank average speed are as follows

1.My range is only 230-270 miles, circa 1 weeks driving

2.I have a basic commute of 250 miles a week- same routes at the same time of day. Therefore the majority of data was recorded on the same return journey

3.The car has a built in average sped function on the OBC

4.Variables I cant control are so large and vary so much over the course of a tank that they even out (e.g. so far this week I've had 2 dry partial commutes (one out, one back not on same day) and 4 wet ones) no to mention the temp going from 20 degrees to 9 and back to 14 in the same 3 day period.

Then there's the traffic and accidents...25 miles in 55mins today

The average speed figure represents (to me) a function of the above noted components, allowing me to guesstimate fuel costs, and review budgets. I can also check the average to see whether can afford a "spirited trip" home, or whether I have to be mega frugal

My ccars OBC counts it as "Key on" speed- essentially if stationary but at position II on the ignition, its calculating..

as above, I've decided that the Scottish weather its too much of a task for one man
