Has any one noticed?

I noticed this a while ago and its getting to me , next time you slow down to a halt do it in these 2 ways ,first gear down and then gradually when you stop depress the clutch , next depress the clutch then slow down and stop. in both cases check the energy meter (l/100km) when you slow down with the clutch depressed , the car uses +- 5l/100km and when you gear down the car uses 0l/100km . why is this ? does the car not use more fuel when you gear down?

on a decompression cycle, your injectors do not inject. When you are idling, your injectors are still injecting fuel.

shot for the info Freerider makes sence , now i can sleep at night i thought the injectors always inject ??? any ways thanks dude

I hate that little fuel economy gauge, I wish I could replace mine with something useful like an oil temp gauge.

 

[DonovanPorter]

agreed , i feel guilty when it goes over 10

 

[freerider]

Mine is useless, my needle always hides away from me :mmm:

Yeah, I feel like a prick when I see that thing, I always tell myself "calm down it's only petrol". :slap:

Then a few days later I have to fill up again :bawling:

This has not been successfully done yet. People have plugged these in, and here are the results:

WORKS 100%:
- MPH
- RPM
- OnBoard Computer Functions
- Lights
- Indicators
- Engine Temp.
- Gas Info

DOES NOT WORK:
- Oil Temp. Needle
- RPM Warmup Lights
- Little orange ODO Tamper Light comes on...which is bad

This is a DIRECT PLUG AND PLAY, but will not work 100%. You be the judge...

Safe Alternatives:
- Bimmian M3-Style Gauges
- UUC Whiteface Gauges
- Silver Gauge Rings w/ Red Sharpie'd Needles

would look seriously awsome though but like you stated above the whole thing needs to work , i mean for that price you would expect it all to work.

I love that needle. My E30 318i does about 10km per liter, but it would have been LOADS worse if I did have that little gauge telling me when I'm being a chop.

Don't get me wrong... I do open the taps every now and then, but then usually no more than 4000 rpm. :hammerhead:

I love the fuel usage guage. Helps me get 7.5l/100Km average.

when you run the car in gear, with the throttle closed, you use "fuel overrun cutoff". when you idle the car, you need fuel again to keep the motor running - hence its more economical to run a car in gear down a hill, vs coasting it in neutral.
