#Aem air fuel ratio gauge power harness install

The actual meter, as far as I can tell is very accurate and works dependably. The plug almost comes all the way out of the auxiliary 12 V cigarette lighter/12 V DC socket. I discovered 2 reasons why.ДЎ- the spring that pushes the (+) contact in the center is much too strong and forces the plug outward, which causes issue number 2.Дў- The (-) contacts are shaped in such a way that there is not enough friction, to keep good contact and allows the whole plug to go outward enough so that minimal vibrations cause the (+) in the center to lose electrical contact. The cigarette lighter/12 V connector plug on the end of the power wire that comes in the kit does not always keep electrical contact in the auxiliary 12 V socket. I have read a couple of the more negative reviews and realized that I did forget to mention something very important.

Without the Air/Fuel Ratio Meter, even with a vacuum gauge, accurate tachometer tool, and experienced ear, without the Air/Fuel Ratio meter, there is no way I could have been able to make such accurate adjustments on the aftermarket, California legal, Weber 32/36 that I use to Fine-Tune the carburetor on my 1978 Toyota Pickup.

Once I got the jet sizes figured out, I had to work back and forth between adjusting idle mix and idle speed along with the accurate tachometer and of course the Air/Fuel Ratio meter to get it dialed in just right. I was surprised at how little of a turn on the idle mix screw makes such a difference to the Air/Fuel Ratio on the Weber 32/36 carburetor. Without the Innovate Motorsports (3837) LM-2 Air/Fuel Ratio meter there was really no way to be sure exactly what was going on with the Weber's jetting, idle mix and idle speed adjustments.ДЄfter rebuilding the Weber carburetor, I used a fuel pressure gauge to make sure I had proper fuel pressure, a vacuum gauge, an accurate tuneup tachometer and the Innovate Motorsports (3837) LM-2 Air/Fuel Ratio Meter. I have it Velcro to the floor rug in front of the Gearshift lever on the 'hump'.Д«ecause of the lack of availability of at least one of the important, can't do without rebuild parts for a Toyota OEM carburetor on this vehicle, I ended up using a California legal Weber carburetor kit.Д®ver since I installed the Weber, 9 or so years ago, it always ran to rich.

I had to mark where to install the 'Bung', remove the exhaust system and bring it to a professional welder.I don't weld.Д¤- I like the fact that it can be calibrated.ДҐ- I really like the fact that it has its own back-lighting because I am using it instead of having to install a Gauge type meter because there is not enough room to install another aftermarket Gauge. I am not even sure what they mean by 'Thickness' for this product.Дў- I gave it 5 stars on 'Accuracy' because, as far as I can tell it is very accurate.ДЈ- I gave it 4 stars on 'Easy to install' because of the work and welding required on the exhaust system that has to be done for the install.

1- I gave it 5 stars on 'Thickness' because it didn't really matter how thick it is.
