It has a carb and Distributer but I am thinking about adding a Lamda sensor with a dash mounted gauge so that I can Keep an eye on the mixture. Where in the exhaust system is the best place to mount the sensor? Close to the head? 6ft down the exhaust? I have a Long center branch exhaust manifold which doesn't bring the ports together for about 3ft after the cylinder head. The manifold is also new (and expensive) so I would prefur to mount is in the exhaust if it doesn't affect the reading. I plan to get a sensor from a car in a scrap yard are there any UK (comon) makes of cars that have better Lamda sensor than others? In the UK they recently banned Leaded petrol. They made Lead replacement petrol available to 'replace' it. Does LRP clog lamba sensors like Leaded petrol does? I can run Unleaded but LRP has Higher Octane rating than Unleaded and is cheaper than Super Unleaded. Thanks, Ade ------------------------------ Date: Mon, 17 Jan 2000 19:47:02 -0000 From: "Gareth Jones" Subject: Lambda Value Hi, I'm new to this game and I'm aiming to start small with a mixture meter, driven by an O2 sensor. I have a lot of information on lambda sensor output values, particularly voltage against lambda value. I know that lambda 1.0 is equivalent to 14.7:1 air/fuel ratio. What I really need to know is what lambda values relate to other air/fuel ratios, particularly in the area of 12.5:1 - 13:1. Does anybody have the answers, or can anybody point me in the direction of some relevant web resources?
