Chinoy - You are right here - Just out of curiosity - what part number do you have on your processor? Also - there should be a coloured dot on the label .... what colour is it?I suspect that the base wiring for the O2 sensor may be in your harness, so all you'd have to do is add the right ECU and an O2 sensor - but I'm not sure. I have an inquiry or two out to the Factory about this sort of thing - but as you may imagine - it isn't a huge priority, my curiosity. You may have a better go of finding out the vital info directly from an Indian dealer who asks of the Factory ..... BTW - The O2 sensor generates "about" 400mv on average (higher or lower for the mixture ....) on average - and I think that's the default in the processor if it gets no input from the O2 .....
