Hello Iwilson , I want to thank you for taking the time to get this information and post it for us. This will save us lots of time in the future figuring this out. If you could help me read the AFR graph , I don't understand the rich vs lean reading. As the AFR lines dip down toward the R/H side closer to the bottom this means rich ? So closer to the bottom 1 to 1 , going up the right side 15 to 1 and so on ? What does the dashed red line signify ?
