Pale is a cheater, he only enters every other fill up, but enters all the miles! Just kidding

As mentioned earlier, PM can account for every mile and every gallon in his log, and is glad to help other members.

Do I recall correctly that he is alternator-less?

No, the alternator is hooked up, it just spends so little time turning that it can't keep up with the car's electrical load, especially at night. Hence, it's grid charged a few times a week.

We should get Mr. Melanesian in on this conversation.

amd was a mis type. As for easing your leg pains...

1st, its a 1.6 and doesn't have that tough of a clutch (although I have that big of a leg)

2nd, clutching into gear is necessary, clutching out of gear is not. Releasing drivetrain load with a careful throttle foot while keeping a very small load on the lever will get you into neutral with no damage to the synchros. I have driven all my manuals like this (especially going into a coast).

3rd, if you are EOC but not P&G, then you must only be coasting to stops. Combining the two strategies will yield gains. Finding the speed that your vehicle likes is also important. This is difficult if you dont have city or rural driving to do, as traffic can determine your ability to achieve these.


Things to try. Ditch the pass. mirror, if you dont want to do the antenna removal or relocate just bend it and reduce the frontal area of it as well as changing the profile of the antenna in relation to the air. There are a dozen more mods that you can make that cost nearly nothing.

Good job on the 50ish mpg, I never was able to do it.

P&G with EOC

Wait, I don't understand how I would do a P&G with EOC



So I go to pulse to say 60mph, then I have to clutch, turn of the engine, and glide down to say 50mph

then reengage the clutch (which turns the engine back on), accelerate at full throttle (to minimize BSFC) to 60mph, then clutch and turn off the engine.

But that would kill my left leg with all that clutching. Is there a smarter way to P&G? I just don't understand how anyone actually does P&G in the real world (although the theory makes good sense)

How does Palemalenesian P&G?

Thanks

Right, P&G isn't the most practical thing in the world, and IMO you can't do it in traffic unless you're on hills that allow you to hold a roughly constant speed.

You've got the right idea, only instead of just dumping the clutch at 50mph, you should do a bump start: let the clutch pedal out for a quarter of a second, push it back in, apply throttle to rev match, then let the clutch out. It becomes very easy to do with practice.

If you have a hybrid, though, you can use the electric motor to restart the engine. It's only due to software limitations that I can't also have it rev-match for me.

why rev match? if I leave the throttle fully open (to minimize BSFC) then the engine will start and go to the right rpm as fast as it can, and then start increasing rpm's as the speed goes from 50mph to 60mph

I guess I don't understand rev matching, can you please explain a little more?

Thanks

The glide is actually coasting engine off - just not coasting down to a stop, but to your prefered lower speed.

Yes.

Acceleration depends on what your car consumes when accelerating.
You shouldn't use too much in the pulse, or it isn't worthwhile.
Pulsing and gliding times are approx. equal - depends on the car though.

In mpg, you should accelerate at better than half your normal mpg for constant speed.

(In L/100km , you shouldn't go near double your normal fuel consumption for constant speed)

It's obviously a lot of work.

Buy a prius and stay under 42mph.
It'll do it just by lifting and pressing down your right foot !

Yes, it hurts the first few times... But once you start training you'll build up those muscles
