DIY: Fuel Economy Gauge for your car (to lower your car's fuel consumption)

[jdplyby]

sir how much po ? where did you buy?

[benoy]

mga sirs, kung equipped ang car ng fc guage (L/100km), kelangan pa kaya nito or that will do? TIA

[ghosthunter]

If your car already has a FC/FE guage built-in, why not use that?

Common sense lang di ba?

the old MB have it as OEM. dati sa W126ko, i rarely made the needle go to the red zone.

the economy meter below the fuel gauge

Wow! Buti na lang nakita ko itong thread na to . Dahil dito ipon mode ako.

Any suggestion na store or brand para sa ganito? at saka kung magkano ang presyo nito. mas madali kasi may idea ng price para at least di ko iisipin na baka napamahal ako.

your reply is highly appreciated.

Thanks for the tip, ghosthunter! I bought one from Concorde yesterday and installed this afternoon (sobrang barok, nakatali muna sa vent-hehe ... will choose a pod later). The verdict? Cement foot. That gauge is merciless! Have to force myself to re-learn driving economically. Will watch for a month but I think I'll see good results in my city driving FC. Sana nga lang hindi ako mabangga kakatingin sa gauge

I can't seem to make it work on a Honda Jazz GD. I've tried tapping for a line everywhere.

how much does the vacuum gauge differ from a tacho meter? i mean do they totally have different functions?

yes they are very different.

tach - measures how fast your engine is turning
vacuum gauge - measure the relative or absolute air pressure.

No vacuum line leading out from the engine's intake manifold? Not even the brake booster?

Maybe you got a leak in the hose (or you have a pinched hose which blocks the vacuum pressure reaching the gauge).
