Have this Verada 2000 KH Xi, was willing to change the gears to manual.. but gave it a thought of how this automatic gear worked... tried it on my Vehicle, other magna's and verada,, works like a charm... Dont know if, it damages any thing...

Try it at your own risk fellas....

Best thing about this is my car gives more km's out of a tank...and here's the hack..:eek2:

- Drive the car as you would normally...
- whenever u want to change your gear high,, accelerate a bit say until the its between 1.5 - 2 rpm.
- Then lift you leg a bit from accelerator...
then within a second accelerate just a little, you will find the gear is changed....

So even in cities,, while m driving at 60km/hr, my rpm be @ 1.2, giving me most out of tank... average per litre is 8km:happy:

Umm, wtf are you talking about?

yeah umm u what?

Lol i think he means to get the auto to change earlier

Yes he ment to just ease on the throttle while accelerating to force gearbox to change earlier, hence keeping your engine in low rpms all the time = better fuel.

So you're still using 12.5l/100kms which isn't that great.

:facejump:just turn the car off everytime when you stop mate

My initial thought to this was an auto short shifter, which wouldn't make any sense at all lol

I do understand what he means though, I used to apply this method all the time in my old car, because of the way the 4sp auto's like to hold 3rd forever before dropping into 4th to cruise when your already well and truly at the speed limit. It does help economy a little, depending on the conditions.

The tiptronic allows you to do that without worrying about revs if your model has it. Another thing to point out is that lower revs do not always equal lower fuel consumption.

Indeed, top gear will never be more economical up a hill for instance if you have to put your foot almost to the floor to get up.

One thing I've found successful in improving economy is light engine braking. When the car is slowing, and a gear is fully engaged (manual - clutch engaged, auto - torque convertor locked), the engine is basically spinning on the momentum of the car, thus using next to no fuel. So its more economical for instance if your rolling down a hill to drop a gear to hold your speed, than sit on the brakes the whole way down. Having said that excessive use might wear the gearbox out quicker.

It'll wear an auto out quicker. In a manual it won't hurt. Do the magna's shut fuel off to the injectors on over-run? I've set mine up to do that so when I'm coating and foot is off the go pedal it shuts all fuel off to the injectors. Minimal saving but every drop counts

like most cars, there is no fuel being injected into the engine above 1200rpm with no throttle. All deceleration/ engine braking uses no fuel as it helps the process/effectiveness. Fuel starts being injected aroun the 1200mark in an auto and a tad under 1100 in manuals to retain a smooth transition back to idle. I engine brake everywhere all the time. Save your brakes. It also forces yiou to leave a bigger gap to the car in front, as eventually it becomes so natural to engine brake that you do it everywhere before you apply your foot brake thus meaning you leave that little extra rooom to allow you to do it.

I think you'll find there is always fuel being injected into the engine no matter what the revs.

No fuel = no combustion. No combustion = engine not running

I'd reckon that down changing will affect the life of an auto exactly the same as a manual - both use friction clutches plus in the auto, downshifts that may cause engine over-speeding are prevented whilst in a manual you can select 1st when doing 100kph and wind the rev counter off the dial.:eek2:

Nah mate, I can prove to you it actually does shut off the injectors using the AEM EUGO, if you need more proof I'll load the software up and show you the settings :P

Page 81 I'm sure.

It is called overrun cut off, most EFI cars especially in recent years use it, most aftermarket EFI systems use it also. I helped develop it in the Wolf Systems back in the mid 90's when they were being set up to run on the turbo 4cyl's and rotaries

You would be surprised how much it will actually save the fuel and no it will not wear out an auto any faster than a manual. Provided you are not doing huge shifts which in an auto you cant anyway will nto hurt the auto at all. In fact, if you look in the handbook for the car they also state on a hill to down shift the auto to assist with engine braking

engine braking is by far the best way to slow down, saves overheating brakes and uses energy already there to slow the car down

Is your sarcasm detector plugged in?:P

;1284762']Is your sarcasm detector plugged in?:P

evidently not... i just have to have my 2 cents whenever someone suggests stop/start driving cause it always seems cheap until things wear out

With my AWD - downshifting the tiptronic to engine brake sends the instant fuel consumption gauge to 0.0L / 100km, so it sound like zero fuel is being injected.
When revs drop below 2000rpm (approx, but I'm pretty sure above 1500), the instant fuel consumption goes up to approx 2.5L/100km.

Technically, it's better to use your brakes when slowing down because replacing brake pads is ~ $100 an end. How much is it to repair/replace a gearbox?

However, I engine brake all the time though - and with the AWD having 3 diffs & 4 driven wheels, I quite often avoid using the brakes at all.


Also, more in line with the OP's topic - I find that while accelerating on anything short of a steep hill, my instant fuel usage is lower in higher gears, regardless of how much accelerator I have to use, so for me to get best fuel economy I use a gentle right foot and upshift with the tiptronic as soon as it will go into the next gear (Auto has speed restrictions, eg: 5th can't be engaged until speed is 43kph+)
