It’s normal to be bouncing around while driving and idling, but should be close to the target 14.7, but the most important is under wide open throttle it should be solid at around 11.2 for a supercharged car or 13.5 for a naturally aspirated car

Hey, question for you. Recently bought a turbo car that is tuned on 93 octane. Drove from Washington to Kansas City, and was not able to find 93 octane all the time, so I had to mix 91/93 octane, filling up whenever I needed to. Last fill up was 91 octane, and I did put the royal purple octane booster. I have not tried wide open throttle since I've filled up just in case, and when I drive normally after car warms up at such, afr gauge is usually 14 -15.5, and when I let go the accelerator, I see the gauge sometimes be at 17, or it would show ( - - - ). From what I understand from your video, it is normal for the gauge to read high when decelerating, but what about the 3 dashes? I plan to fill up on 93 octane whenever I use up all the fuel. Thanks in advance

[@JonTostanoski]

The triple dash on a AEM Gauge means MAX Lean. These sensors are known to go bad but when you put your foot into it it should be lower then 14.7

[@yoyyoy4789]

whats the range for perfect AFR? between 12.7-16.7 right? But 18 is not too lean?

[@ethelmini]

The chemically correct AFR for gasoline is 14.7(air) to 1(fuel), That's by mass - air is obviously compressible so you can't compare volume. Numbers above 14.7 mean the engine if running lean, meaning there's excess oxygen that can literally burn exhaust valves & pistons. combustion will also be faster & hotter, which can cause preignition. Numbers lower than 14,7 means there's excess fuel. You'll get some cooling effect by the fuel evaporating but what you're mostly doing is wasting fuel and producing more pollution.

[@mareksumguy1887]

10.1-10.3:1 is WAY too rich for a NA motor. Your Honda can make maximum-safe power at around 12.8:1. Maybe your sensor is not reading accurately. Do a free air calibration of the sensor... or try a new sensor.

[@ΔημήτρηςΤζιωτζιος]

Mine reads 12-13 during start up for about 5-10 seconds then goes back to 14-15 afr is this normal ?

Yeah, startup is in open loop so it’s preset and then when it goes to closed loop it starts making adjustments with feedback from the sensors

Hey Danny, I unplugged my MAF to test if it was causing my backfiring/missing. Now my car is driving around normally 11.5 to 12.5 a/f. It's obviously very rich now. Any ideas?

[@ajohnson1066]

I think the ECU has a very safe default fuel map loaded that it defaults to if its missing any input from the MAF or wideband

[@geogmz8277]

Briefly is 14.7:1 on gas.. Meaning: 14.7 parts of oxygen/air 1 part of gas These figures can change depending the type of fuel.. Alcohol needs way less air to burn than regular gas..

[@dannyjohnsonsgarage]

The ratio of fuel to air will not change depending on what fuel you are running. It is still a ratio of the end result of air to fuel

[@mareksumguy1887]

Danny Johnson... wth are you talking about?!. Lambda 1 for Gasoline is 14.7:1.... for E85 its 9.7:1... for methanol its 6.4:1 afr

[@imTriiBz]

these gauges are all calibrated on gasoline scale, so danny is right. Even with e85 or other fuels, the correct number will still be 14.7. its all calibrated on the one scale as if it were gas despite having a different ratio

[@mareksumguy1887]

Yes i know that these sensors measure Lambda... so Lambda 1.00 afr for gasoline (14.7:1) and ethanol (9.0:1) will both read 14.7 on the gauge. But i don't think thats what Danny was talking about.

[@imTriiBz]

yeh now that i read his comment i think he thinks that all fuel have the same AFR ratio because it converts to lambda, maybe doesnt know the ACTUAL ratio is different

If the gauge is working properly you’ll want to be in the low or mid 11s under full throttle or you’re runnning lean and can melt a piston or pre-ignite the fuel and cause detonation and break chunks of piston off or even bend a rod. You’ll want to verify you have proper fuel pressure as well as a proper tune

I know this is old, but while idling, a healthy and in tune NA engine shouldn't be flactuating too much. Any jumping around under 1 point is fine. If you have more than that you may want to look at plugs, air filter etc.

Hi, I have a question and you definitely seem to know your shit. I recently picked up a car and it had one of these installed but the car is n/a my question is when I'm driving the car the ratio bounces all over the place but gets really lean at idle. Is this typical for a naturally aspirated engine or could there be something wrong? By lean i mean that it gets up to 17 and then the gauge just goes blank with three lines like it's getting so lean that the gauge won't even read it anymore. It only gets that lean at idle though and most of the time only for a couple of seconds.

[@dannyjohnsonsgarage]

Something is not right. Forced induction or n/a, it should be 14.7 range at idle. The only difference is yours should go into the 13s at wide open throttle.. my mach 1 is n/a and it was hitting 12s because of the tune being rich

if you're just idling or cruising, is it okay if the readings are all over the place? I understand that if you let of the gas it will lean out, but what if it leans out while driving or letting the car warm up?

[@dannyjohnsonsgarage]

It is normal to be moving around slightly as seen in the video and fluctuating between 14.7 +\- a full point and at 18 under decel, but ultimately lean is hot, so if you’re seeing 16+ normally a lot while driving and not decel I’d look into some kind of issue like a bad fuel pump or clogged injector
