Introducing "LOG"

[Arragonis]

I have asked this before, can anyone explain the LOD gauge ?

I'm told it is airflow and torque limits. How is it worked out ?

[PaleMelanesian]

As far as I can tell, it's proportional to manifold vacuum. I guess that means it's calculated as a percent of airflow from zero = total restriction = 0 LOD to wide open = ambient = 100 LOD.

As I develope my skills at LOG [ing] my fuel economy keeps getting better. The most resent estimate is 13.3L/351.2km = 3.787L/100km or 62.0mpg so far on this tank. I still find it hard to believe how much differance this method makes.
August 23, 2011 16.0L/430km = 3.72L/100km or 63.17mpg
August 24, 2011 18.5L/504km = 3.67L/100km or 64.03mpg
August 25, 2011 21.3L/580km = 3.67L/100km or 64.03mpg

Congrats! I'm really glad the regimen description benefits you. A good P&G discipline has been of amazing effect for me too, and a really big surprise this spring/summer. P&G is awesome, DWL is awesome, EOC is awesome, but until you realize how to integrate the three techniques effectively some big benefits are lost. The acronym "LOG" (ugly as it is) combining dwL, eOc, and p&G helped me learn what the PaleCivic knew.

[PaleMelanesian]

indeed. That's a great result!

Thanks guys, the challeng now is driving in the dark in the morning going to work. The longest engine off coast is around 1km - 2km so not much of a problem. The thing I notice is the headlights dimming a little. I notice; PaleMelanesian that you refer to charging Battery, How long are your EOC's that you need to charge your battery... do you have any other suggestion about LOG'ing in the dark?

I am anticipating and beginning to have the same problem. My battery is four years old and it is I think weaker as a result. I will sometimes briefly bumpstart on theory that the alt will kick right in. Helps a little, but only for a short while. My other plan is more LED bulbs (headlights and running lights next) and a new deep cycle battery.

Yeah, it's too bad our cars have such tiny batteries, and no space to fit a bigger one.

I use a 1.5A charger every night. It uses 0.1-0.15 kwh each night, and a little more if I've used the lights a lot. My commute is 10 miles (13 during school dropoff days). Half to two-thirds of that is eoc. Some coasts are more than a mile if traffic and lights work out. In summer when I don't need lights, I can skip days between charges. In winter, charging every night is barely enough.

LED's would help. The taillights draw about half as much as the headlights, so swapping them would remove 1/3 of the power drain. Any time I'm stopped at a light, I use the parking brake to save the power draw from the brake lights.

You can have any kind of battery you want. Go to a camper store or a boat store and get a battery box, then mount that securely in your trunk. Get a set of jumper cables and some battery terminals, then just run the wires forward and connect them to the battery wiring. If you're especially cautious, seal up the battery box and run a vent tube to the outside somehow.

LED's sound like the better plan from an energy reduction point of view "wast not want not", I have instaled LED,s in my motorcycles but have not done the same for my car. I will see what is available and how much power they draw. On my 80km [50 mile] round trip commute I only have to stop once on the way home at the bottom of a hill. I do a lot of "bump starting" so I don't have to use the battery/starting system much. It seems to me that adding more battery mass woud be the last resort for this potential problem. there are also very expensive light weight batteries if "money is no object".
