[QUOTE="oexing, post: 107276, member: 1493"] To be open, I don´t quite know what it is all about A/F sensors, sniffers and all that stuff. A modern car engine mainly uses data from the lambda/O2 sensor welded somewhere along into the exhaust pipes, some have another sensor a bit behind. No sniffers in the exhaust on the road I guess. So I did just that on two Horexes, pre and post war, a Honda Clubman, a BMW R 69 S and , ah, a Ford Capri and the 3.8 E-Type. That worked for me and you don´t need a second hand ex pipe, just find a place that is not too visible for onlookers.. Now look at my photos, you better do TIG welding the M 18x1.5 adapter with stainless and in short intervals and you even keep the chrome shiny. The sensor has two wires for heating it so the distance from ex valve is not critical at all. The sensor is hooked up to a mini digital voltmeter that tells me 0.5 V is perfect, up to 0.7 V is a bit rich but OK, below 0.5 V is too lean. I could use a rolling road at my friend´s workshop but prefer to do road tests for better feel at all throttle positions and test driving as long as I like .
