LM2 what data am I seeing here?
I am working on bringing my LM2 directly into my USB on my laptop so I can switch it more easily between vehicles. Previously I have used analog and brought it in through the A/C pressure switch on my cars. I have it working, it doesn't dissapear as it seems to for so many, but I am not sure what the data I am seeing is. When logging it is reporting the AFR on the screen of the LM2, but in HP tuners I am seeing an ever changing 3 digit number followed by two decimals. (example 521.32) What is it reporting and how do I turn it into an AFR?
Thanks, Roy
