FS: Haltech Air/Fuel Meter (AF30) + Apexi SAFC!!
i have a haltech Air/Fuel meter the Halmeter AF30 for sale. Its already wired for a 3 wire o2 sensor but the sensor isn't included. $110 OBO
Also have a Apexi SAFC thats missing the mounting bracket and instructions but comes with all the wiring. $180 OBO
both units are used but in perfect working condition, i'll see if i can get some pics up but i have none as of right now.
Email me if interested at dingusjt@yahoo.com, thanks

Re:FS: Haltech Air/Fuel Meter (AF30) + Apexi SAFC!!
I've never used the thing but was told it was one of the best...
this is just some info i came up with off of google.
"An essential part of tuning any high performance engine is knowing whether the air fuel ratio is correct. A rich mixture will lead to a loss of power, while a lean mixture may result in detonation. The HALMETER AF30 provides a thirty LED readout of air fuel ratio, right there, in the cockpit, while you drive.
EXHAUST GAS ANALYSIS WITH THE HALMETER AND THE LAMBDA OXYGEN SENSOR
The design of the Lambda or oxygen sensor provides a signal which is easily interpreted by the HALMETER AF30. The sensor produces a small voltage output by comparing free oxygen in the exhaust gases with ambient oxygen outside the exhaust system. This voltage is created when the sensor is heated to between 360 degrees centigrade (680 F) and 900 degrees centigrade (1 650F) and varies between zero and one volt. The AF30 processes this voltage output and displays the result via a series of red, yellow and green LED's: The red lights for lean, yellow for the stoichiometric band and the green lights indicating mixtures likely to produce maximum power. It should be noted that, in the event the sensor is located in the exhaust where the temperatures are at or above the maximum, a reduced voltage output will result in fewer lights, in the green band, being lit at rich mixtures. Dividing the small output from the sensor into thirty incremental LED's gives the HALMETER AF30 superior resolution compared to other instruments of its type. More info? or e-mail us.
The HALMETER AF30 Air Fuel Ratio Indicator offers the tuner a low cost, attractive unit with thirty LED indicators that signal lean-optimum-rich.
The HALMETER AF30 Air Fuel Ratio Indicator works on all engines, carbureted or injected, and with gasoline, alcohol or propane fuels. When used with programmable EFI systems, it helps establish fuel maps and makes the mixture trim control a more precise tool for on track tuning."
