Air/Fuel Mixture Gauge - Lambda Display

[chuaed]

Air/fuel ratio is one of the most critical aspects of tuning an engine. All kinds of performance modifications can cause a combination to run rich or lean, which hurts the engine's power output, fuel efficiency and longevity--especially when it's running extremely lean. So, how do you figure out when you've got the mixture balanced for optimum power and efficiency? By using an Air/Fuel Mixture Gauge. Each gauge uses an oxygen sensor and a microprocessor to accurately determine if your engine is running rich or lean, regardless of load, rpm or modifications.

saan kaya may mabili at nagkakabit nito dito?

Actually you can have this ordered and shipped here from online stores. You will need to match the oxygen sensor with the proper a/f meter. I have used my stock sensor and a narrow band a/f meter and its just eye-candy. Kinda useless for any tuning and only barely useful to monitor the engine condition. One of the major reasons is the oxygen sensor is a stock single wire type which is sensitive to operating temperature, if the radiator fan turns on and blows on the sensor, the readings become inaccurate. Maybe if I used a self-heated type, it would be more accurate. A wideband sensor and meter would be better but I think this costs a lot more.

its too expensive if i ordered it online, furthermore i don't have the technical knowhow and the time to install such device...

i need the gauge because my car is running on autogas... thank you

just curious, pwede bang pang EFI and carb to?

[finchy18]

pwde at carb yan.

yes pede....modern day EFI usually have an O2 sensor installed and the signal is used by the computer for the fuel injected.

kaso depende sa controls ng existing EFI mo baka mahirap i-add yung O2....hindi naman (not that i know) pede i-tweak yung EFI settings manually eh...

pero sa carb pede mo i-tweak yung A/F....

mahal talaga ang ready made....the O2 sensors is a device that converts the sensed O2 into electrical charge as small output voltage....and the reader (yung visual output) can be anywhere between an analogue or digital read-out....merun mga DIY nito pero yung O2 sensor must really match the type...most downloadable O2 DIY readers are cheap to build (less than a P1000) pero pang single wire sensors ito.

yung pang 3 or 4 wires (if I am not mistaken) medyo mas complicated and I have yet to see/download a schematic diagram nito para maging DIY.

Bosch Philippines (in Buedia) can sell you the O2 sensor although I'm not sure kung meron silang single wire sensor.

Well, if you have a relative who could snail mail it to you, that can save you a lot of money in shipping costs. As for installing it, you'll probably need a mullfer shop to weld the sensor plug nut-base into your headers and another shop who is familiar with car electronics to install the guage & associated wiring.

You could probably check your car if its already equipted with an O2 sensor, that would save you some more money if you don't need to buy one.
