Någon som har testat en sådan här apparat?

Fick ett tips av en som sa att det bästa sättet att justera in förgasaren var att använda en sådan hära sak som Dalhems säljer,för då kan man åka ut och belasta motorn och se hur bra bränsle motorn får.Länk till Dalhems

Air/Fuel Meters
The HALMETER AF30
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.
The HALMETER AF30 Air Fuel Ratio Indicator kit is supplied complete with meter, wiring harness, pre heated oxygen sensor and exhaust fittings. The oxygen sensor is of a very high quality, and extremely sensitive.
Price AF30: 3695 Sek (about £255 ) including VAT and freight inside EU (European Union). Outside EU 2956 Sek. Around US£ 199Note that if you live outside EU, local taxes and duties can be added when arriving to your country!
Funderar på om man skulle ta och investera i en sådan.Det är ju bara att svetsa in en muff på heddersarna så att man kan skruva dit lambasonden ,sedan så ar det ju bara att plugga in mätar och justera förgasaren.
Är det någon som har provat en sådan sak,isåfall har ni varit nöjda?

kan ju dra några paralleler.. Jag har även knyckt ett par bilder på JOBYs hemsida för att det ska bli lättare att förstå..
