X-Series Wideband Gauge Set-Up and DYNO RUN

Hunter, Kirk and Sam come together to show off the X-Series Wideband Gauge! Starting with the basics and making their way to the dyno, everything that you may want explained about the X-Series Wideband is all here!

X-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition. The controller’s high-speed digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.

Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM’s Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases (transport delay) can affect deadtime, it is not the only source. Often, the sensing elements response to the gas is the largest contributor to deadtime when an engine is in high RPM under load.

When tuning an engine using wideband AFR feedback control on an inertia dyno, deadtime affects the data you are looking at because it is reported in a different operating location than when it actually occurred. This means with long deadtimes, whatever changes you make to the base fueling will likely be in the wrong location. This can be particularly dangerous to high compression and high-boost forced induction vehicles, and EFI systems that use feedback control to auto-tune.

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 had one go those first Aem widebands. I was very happy you offered it. it worked pretty well

[ford]

The counterfeit message means don’t use eBay.

[NITROKID]

I see AEM is rocking those harbor freight tools ICON ftw!!!

[PaulyDownUnder]

Great video guys, this really clarified a lot of questions i had. :)

[colemcmeans]

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.

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.

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

[MichiganRay]

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

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?

[zakurajr]

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

[thekingsmen]

For the obd2 thing i cant seem to find it sold by itself

[glisedan]

I'm assuming if purchased from Holley you should be good to go, correct?

[Salbritt]

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?

[bradbrown]

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.

[robertboicourt]

2008 - wont work on a 99 with the obd2 and mpvi2+?

[KGisthename]

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?

[mohammadh.jamshidi]

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.

[hosrow]

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?

[UnTamedMustang]

Wow those gauges were not close . Im buying the X 30-300 series right now and looking for good user testing videos .
