| What scale does the air/fuel ratio show on the display? The reason I ask is that I have the units set to the air/fuel scale in the user software but it reads two different ways. The a/f gauge on the laptop screen reads standard a/f (14.7=stoich for gas). But the log list and the logs are on a scale that is based on the stoich of the blend of fuel in the tank at that time.
Thanks in advance. | |

| Whatever the stoich point is. Read lambda. | |

| Ok, thanks. So for example, say I have exactly E85 in the tank, what will read on the CAN gauge at 1.0 lambda? | |

In your ProEFI folder you've a directory called "Documents". In Documents you've a filed called Air Fuel Conversions. That will tell you everything. | |

| Thanks. I've seen the conversion chart. But I'm curious which will appear on the CAN gauge for stoich of E85. 1.0 Lambda, 14.7, or 9.8? | |

| regardless of fuel type, stoich lambda is 1.0.
To get the AFR that you see in the logs, proefi is just multipling lambda by the stoich value of the ethanol percentage your flex fuel meter reads.
So if you have the gauge set to lambda you will see 1.0, while the AFR display will be 9.8 | |

So if you have the gauge set to lambda you will see 1.0, while the AFR display will be 9.8 So on the large CAN color display, it will display Lambda? Do you have a choice of how a/f will display? Thanks. | |

| no it doesnt display lambda nor do you have a choice on gas scale AFR | |

| Ok, thanks. That's kind of what I thought. I can't really use that gauge because one of the main reasons was to get rid of my AEM a/f gauge. Oh well.... | |

Thanks. You can display lambda on the Display/Logger, you can change to DesEQ, or A/F as well. | |

| Also there is no reason not to read lambda! | |
