[QUOTE="defcon1, post: 1712625, member: 30064"] Starting this project. Actually very easy to build as the whole device is based on a single IC. I did it once before, but lost my notes so am going to have to research it again. Shouldn't take long as I know what to look for. The final device would simply consist of a small pcb with a row of LED's consisting of 3 colours....red (lean), green (stoichiometric), yellow (rich)... :smile: As for connections...simply connect to an existing O2 sensor...or if you are worried about tapping into the, by now, brittle wiring...get a second hand O2 sensor from the scrap yard and drill/weld a mounting into your exhaust...in front of the original cat converters. It's the exact internal mechanism that you get when you buy an after-market AF Ratio meter for RM 250 - 400. Heh...with 2 units...you could independently monitor both sides of the V... :smile: [/QUOTE]
