Sorry, either I don't understand or I haven't explained it well enough. I don't need it to read richer readings, i'd like it to read leaner. I'd like to read Lambda numbers that are higher than 10 or an AFR of over 200. The current lookup table stops at 10.119 and i'd like to calculate all the lambd...

I have a diesel engine and would like to be able to read lambda values at idle and cruise, which are leaner than the arduino code is programmed to support in the lookup table. Is there a more detailed lookup table available or will this require the values to be calculated on the fly? I can't seem to...
