I really had my sights set on an AEM X series wideband gauge, I just find it such a beautiful gauge as well as a very useful one to have. Whilst shopping online for one, I noticed there were many, many bad reviews about these, especially regarding the used Bosch 4.9 sensors. Because of these reviews I thought it's better to buy one here at an official dealer so I want have any issues with warrantee if it goes bad. Then I noticed that the official distributor didn't offer any warrantee for this product anymore, so I sent them a message asking why not? They replied that the Bosch Sensors are so bad that AEM USA has by now washed their hands completely of them and didn't give a warrantee on the sensors anymore. I am sad, because I had my eye on this product but I am super happy I didn't get one.
I have one of your AEM X-series gages on a 1995 Harley Heritage. I love it. Using it to tune a Mikuni carb is super helpful to get the carb dialed in as well as monitor the AFR while riding. Trying to record the AEM with a Gopro while riding; however, is giving me some problems configuring the Gopro settings to record the AFR display. Apparently the flashing rate of the AFR meter display and the Frames per Second recording rate of the Gopro are resulting in the Gopro not seeing/recording the AFR readout completely and sometimes not at all. I have been working on the Gopro configuration, but haven't hit on the right combination of settings yet. Can you tell me the frequency of the AFR meter display? Does it change with RPM? I noticed on this video there was a slight flickering also.
what could cause the wb to quit working in hpt scanner?... gauge reads fine. serial connection was working until the other day, now it just displays 9.99 in scanner. got a new gauge and no change, mode button doesnt work either unless the sensor is unplugged.
Good question. It's best practice to start the vehicle when the sensor is still heating up instead of once it has already heated up, because a heated sensor will be not thermally shocked from cool air at cold start. But if you key on to listen to your stereo and then key off without starting the engine, it will not damage the sensor.
I don't understand why on wire diagram you recommend a switch, but then you say not to wait the sensor to heat up or not keeping the sensor mounted without use it. Why should I install the switch then? Tnx
Planning on getting one of these but on my car all aftermarket downpipes have extra o2 bungs like 4in after the turbine housing exit... so i need a separate bung to mount it farther away
Whats with the desclaimer? Never heard of a guage breaking the law. How would this violate it? I am curious. My car is emissions exempt in AZ would I be ok?
Thank you for the great video. I recently bought an X-Series for my 1984 Austin mini. The laptops nowadays do not have the serial connectors. How do I connect the Guage to the laptop? What software do you recommend to use for logging and evaluating the logged results? Do you have a tutorial on how to read and assess the logged information? What accessories do you recommend I purchase for my AFR Guage?
How do I connect the Gauge to the laptop? A serial to USB adapter can be used, then the raw data can be viewed in HyperTerminal or RealTerm. There are also other 3rd party tuning software that accepts inputs as serial. What software do you recommend to use for logging and evaluating the logged results? We recommend AEMdata, However AEMdata logs will need to be pulled from an AEM logging Device such as our Standalone ECU, CD-5/7 displays, or our older (discontinued) AQ-1 data logger. Do you have a tutorial on how to read and assess the logged information? We have several AEMdata tutorials on the AEMpower TV channel. What accessories do you recommend I purchase for my AFR Gauge? That all depends on what you are looking for and what your goals are, please give our tech support a call so we may discuss possible options 310-484-2322 Ext 303
What is best procedure then when tuning as the ignition (and AeM) need to be powered up to flash or scan computer before actually starting the vehicle? In the video you state this is not good to cold start air on hot sensor. How do you avoid this issue then when tuning?
So my weld in bung that is in my X series box is not magnetic. It says it is mild steel but my magnet wont stick. I can use my mig welder that I use for steel to weld it correct?
Are you able to replace the O2 sensor if it goes bad? From the previous videos it was informed that the x series does not allow us to replace the O2 sensor if they were to go bad
Hi, I am running a V8 Chevy small block with a carburettor, now do I need 2 AFR units for each bunk of exhaust line or not? Typically I think since there are 2 separate exhaust lines then I should use 2 AFR units separately for each, is this correct? please help.
@AEMpowerTVelectronics i bought a 30-0300 that im pretty sure is fake how can I get it verify it i have an older one same model the new one back plate looks a little different and qc sticker is white not green
Interested to see if there is a way I can connect it to my stock ECU for logging purposes. All of my O2 sensor inputs are 2.5v. trying to find one that is 5v. its a GM delco e78 ecu if anyone has any ideas. no access to can bus and my software does not support serial. If I would have known MEFI Pro was such a pain I would have gone with Haltech.
Catalytic converters can alter the exhaust gasses enough that it may affect the final air fuel ratio reading, so ideally, O2 sensors should be installed ahead of catalytic converters.
You can put one wideband in a common collector after the two pipes come together, but most V6 and V8 applications run two widebands so that you can see AFR from bank to bank. One way to do this using our controllers is to use our X-Series Inline wideband controllers (30-0310) and an AEMnet CAN gauge (30-0312). You can send the data from each controller to this gauge over AEMnet CAN, and toggle in between the two banks using the buttons on the faceplate. Or, you can use two X-Series widebands, of course!
I know there is a bung included to weld in , but would using an oem bung on the exhaust be okay as well ? I’m assuming it would cause a check engine light since the ecu wouldn’t be reading that o2 sensor anymore and would be used solely for the gauge . Also , if I didn’t want to use the CAN, and serial logging would I just leave them not connected ?
Correct, if you don’t want to use the outputs simply leave them disconnected. For the bung - yes, removing the factory O2 sensor can cause a variety of problems if your vehicle is using it calibration.
hey guys love the product just tryng to diag something i have going on with mine its stuck on 8.6 and i had a loose ground so i think that may have caused a shock scenario to the sensor itself just looking for some insight please and thankyou
Absolutely. Our widebands are used on all types of vehicles, including carbureted cars, trucks, and motorcycles. Depending on what type of tuner you are using it may have an input that will allow you to see and maybe even log AFR in your program, but you will need to confirm that with the manufacturer of your tuning device.
That is because the X-Series responds faster than our classic digital wideband. They weren't reading differently, the X-Series was just picking up the changes faster.
really was hoping to see more of the installation in detail. but instead I watched a really long commercial🥱 now I've got to go try to get that 18 mins back somehow...👆👉👎
I had one go those first Aem widebands. I was very happy you offered it. it worked pretty well

Everything that Bosch manufactures is junk.
The counterfeit message means don’t use eBay.
I see AEM is rocking those harbor freight tools ICON ftw!!!
Great video guys, this really clarified a lot of questions i had. :)

Will the O2 sensor be damaged by having it power up, without the motor running? Like listening to the radio without the motor on.

For the obd2 thing i cant seem to find it sold by itself
Can I use this for my tesla?
I'm assuming if purchased from Holley you should be good to go, correct?
will AEM swap for my old gauge :)
Why was the analog wideband gauge discontinued?
2008 - up........this wont work on a 99 with the obd2 and mpvi2+?

I have a rear engine and rear exhaust. Is there an extension for the sensor? I think I need an extra two feet over the standard 8 foot cable.

@@AEMpowerTVelectronics I think you missed the bus not being able to data log straight to a computer.

Wow those gauges were not close . Im buying the X 30-300 series right now and looking for good user testing videos .
Do I have to put the wideband before my cata or after?
Catalytic converters can alter the exhaust gasses enough that it may affect the final air fuel ratio reading, so ideally, O2 sensors should be installed ahead of catalytic converters.
Do v8 engines need 2 o2 sensors or just one?

I need in pakistan for coure 660cc ef-rl tuning
good day sir, can i use it to ordinary sohc motorcycle for afr tuning?
Absolutely. Our widebands are used on all types of vehicles, including carbureted cars, trucks, and motorcycles. Depending on what type of tuner you are using it may have an input that will allow you to see and maybe even log AFR in your program, but you will need to confirm that with the manufacturer of your tuning device.
so its not safe to buy on amazon.
Wait, what... I didn't get my friggin sticker!! Smh...
Would this also work on a classic Btitish car with positive earth wiring?
Thank you
As long as the gauge is wired to a strong power source and the polarity is correct, it will function.
Is Summit Racing a legit vender 😂
Good day sir, can i used the x-series to my mistsubishi lancer 1999 model carburator type, thanks
Both the gauges where reading abit different why was that?
That is because the X-Series responds faster than our classic digital wideband. They weren't reading differently, the X-Series was just picking up the changes faster.
Get that boy a lift to work on that car...
X series giveaway?
My senser is on hart
really was hoping to see more of the installation in detail. but instead I watched a really long commercial🥱 now I've got to go try to get that 18 mins back somehow...👆👉👎
