Thanks for the thread--it's reminded me again why I love my manual tranny!

In all seriousness, pretty neat experiment.

If your brave you can make a TCC lock switch
Don't forget aeromods if you spend any significant time on the highway, they will help alot, just not in the city...

I also drive an atx and feel your pain in city driving. However, I can usually get 30+ in city. Improving my driving techinque has helped a lot.

Watch the pictures there are many measured fuel consumtion curves. I was not able to find picture adresses?

From curves you can see that your aero effects most to the fuel consumtion and the engine is the second biggest factor at those speeds.

My lupo 3L consumes 3l/100km @ 100 km/h speed .

I was surprised at Hägar's fuel consumption when stabilized at Vmax (187 km/h GPS).
It was less than 10L/100km - though it obviously takes a far higher fuel consumption to get there.


Climbing inclines at 130 kph rather than "eco"-speed (95-105 kph) also reduces fuel consumption in my car - the deal-killer is the acceleration of course.
At Vmax, the fuel consumption to go up comparable inclines hardly increased and was lower than while climbing at 105 kph, which tripled and quadrupled consumption to well beyond 12 L/100km.

Weird things seem to happen @ speed

Can't grab the picture's URLs either, but you can grab the pages where the graphs are:

I get better instrumentation averages at higher speeds, but better tank to tank if the speed is kept low.

Maybe its something to do with the sample / calculation rate ?

It is very unfortunate that widespread, easy to access engine ECU/ECM programmers don't exist that are plug and play and cheap to own like the scanguage.

If I could easily change the shift points in my autotragic and change its timing a tad without massive effort I would probably still own the buick lesabre.

I think maybe some more effort for easy to use DIY solutions on this front need to be made, if the auto makers won't do it, you should have the ability to do it yourself.

Having to desolder and socket the eeprom in the ECU, get a burner and figure out the code yourself, really isn't plug and play or easy.

Anyone want to figure out the AVEOs eeprom for shift points to help this guy get the most out of his car ?

Interestingly I find something similar which I have always attributed to momentum keeping the vehicle moving and saving that fuel guzzling shift back one gear and unlocking the convertor.

At 95 kph I can drive to work on the freeway with no changes but at 85 kph the transmission shifts back , for the few hills there are , enough to move the revs up from around 1600 to about 2000.

This in turn is enough to move the fuel used up to around 8.0l / 100 (US 29 mpg) from the usual 7.3 (US 32 mpg) or so. A jump of about 10 % which is a reasonable amount.

Peter.

from the small amount of research I have done my sweet spot is 55 to 65, if I stick it in I can achieve 30 plus in my 1999 camry which is a feat in itself

My 010 cobalt gets the best FE between 25 & 45mph depending on conditions. P&G is different.
