[@davidchmelik6592]

now ive run into another issue. I followed ur video to the T and in my scanner the aem eq ratio is set to read in lambda but it shows afr. I went into transform and changed it to my aem 30-4110 and I cant get it to read in lambda therefore my "maf error" table we setup is reading crazy high numbers.

[@GoatRopeGarage]

Make sure your gauge is set to lambda, the data from it will always match the gauge and will show up as such no matter what you select, you can select AFR on the scanner and it will still read lambda when the gauge is set to lambda. Let me know!

[@jonathanrobinson8176]

How do you connect AEM X to the HP tuner mpvi2?

[@reborn74nova]

First thank you for this video. I want to make sure I understand one thing. Basically the OBD port connects to MPVI2 with OBD extension cable or MPVI2 connects directly to the OBD port. Then the MPVI2 unit has a USB cable that I would connect to the USB hub. The AEM 30-4110 has a connector with bare wires. I use that to make the RS-232 Serial Device cable and connect the serial to USB adapter to the USB hub. The same USB hub that the MPVI2 is connected to. Then I connect the USB Hub to the computer. Am I correct with the setup? (Basically Wideband and MPVI2 are connected together and sent to computer via a USB hub.)

Yep, nailed it!

You have two output options, an analog and a serial (rs-232), neither if which are supported by USB natively, the serial adapter is the easiest and cheapest way of doing it.

[@robertwcote]

@@GoatRopeGarage I guess I don't really understand what the serial connector is doing beyond being a pass-through then. Does the serial-to-USB adapter cable manipulate the signal in some way?

[@GoatRopeGarage]

@Robert Cote yep, it changes the 232 signal to something that can be read via USB. Unless your laptop/computer has an old school DB9 serial port you are going to have to use a serial to USB adapter. You have to think of USB as the highway in which the data is transferred on, the serial to USB adapter puts the wideband data in a car so it can drive on that highway.

Just create a custom channel list in HP tuner to only show Wide Band information, if using a P01 gen 3 ecu use Pin 55 on blue connector to analog output + (white wire on AEM) and the brown wire on AEM goes to Analog output which is blue plug pin 40.

Chris, this model seems to only have an analog output, which would only work with the pro version. You need one with serial RS-232 to bring it in without the pro.

How would you hook up a lc2 wideband up with hptuners?

[@hassanabas1549]

Did i understand this right So if I have a mpvi2 with an aem wideband x series with obd2 harness I plug my new serial port USB side to the laptop and my db9 to another female db9 and through both of them will be the power and ground wires from my wideband gauge which used to go into a cigarette lighter wiring from the tuning school and now I can tune 3rd Gen gm vehicles without buying a pro feature and a pro link right? But now since I replaced the ciggerate lighter wiring to this serial db9 serial ports where is my wideband getting power from laptop ?

[@nickspall4552]

Can you use a 5 volt analogue out put with the mpvi2 using the rs232 serial adapter like you have done on the mpvi1?

[@TwinTurboRamAir]

My fix to the wideband disappearing from channel list: I had all the cables plugged into the laptop and had the scanner open and ready, started the car, hit scan, the wideband stayed in the channels list and histogram started populating as it should. And I'm running Windows 7.

[@waynesworld5657]

Is this wideband & lambda tuning set up an ideal path for dialing in a gen III lq4 vs narrow band afr ? I have an OG mvpi looking to get my feet wet tuning my wife’s 01 denali.

[@timvandyke5358]

Thank you for this video and the links subbed.

[@trumanbuckley]

Someone please help me out. I take the blue wire from the harness and put it on terminal 2 and the black wire from the harness to terminal 5? Or do I ground the black wire and separate ground to terminal 5?

[@ivancastillo7872]

Disculpa no tienes los drivers o programa para poder vincularlos ?

[@j.finesseflights1403]

I'm getting close to installing my 0300 to my lm7 shittyrado!

[@krishill6505]

So could you run your analog signal lines in place of a narrow band o2 back to your ECU? And still be able to use the wideband for tuing?

[@GoatRopeGarage]

No, the narrowband works on a 1v range while widebands are 5

[@krishill6505]

@@GoatRopeGarage thank you

[@Mike_Neukam]

Some wideband controllers have a programmable output that will simulate a narrow band O² and can be installed that way

[@DCLT1415]

@goatropegarage On Jeremy's post you can't look at the comments to see what was said about where the wires go in the rs232 connector....

[@GoatRopeGarage]

Blue to 2, black to 5

[@chrisbryant1657]

I purchased the exact same WB O2 sensor you have. Will the setup your describing work with the original HPTuners version 2.2 that was discontinued a long time ago? My laptop os is windows 10 with usb 2 ports. 1998 z28 Camaro.

[@Elcoboyz]

Damn ive tried every type of serial connector and just can not get my hptuners to see AFR. as soon as i start scanning the channel just disappears..

[@israellujan8432]

is there a way to run other gauges similar to the wideband using the serial input instead of using the analog on the side of the mpvi1

[@fury2012]

I didn't notice any noises on different cars, there was one in all the time in which there was noise, but it had rotten wiring, green connectors. But in all cars all engine sensors are analog. And everything works every day for years. Why do I need a digital if the signal update frequency will be 50Hz, make it more, the memory is overloaded with a large data flow

[@Cambo540]

Hey man, got my AEM connected to rs232 to HP and the gauge and computer are reading different values. Gauge is reading rich at 13 and HP is reading 1.35 lambda. Any ideas? You been a huge help. Thanks.

[@mohammadalshirawi3239]

Hi, I have a question on the new mpvi2 device , so my setup is a gauge from (WB brand) hooked to lighter plug to give it power and hooked to O2 sensor and I customized a cable to connect the gauge to a serial port then from there i got a serial to usb adapter and then i plug the usb into my laptop or i get multi usb hub and connect it to the mpvi2 ? I am confused in the last part where do i plug the usb is it into the laptop or a usb hub with the mpvi2 ( which mean both of them in one hub )?

[@GoatRopeGarage]

Both to the laptop, if it's one of the supported serial wideband sensors the software will see it when you add it to the parameter list.

[@mohammadalshirawi3239]

Goat Rope Garage is there wideband that do not support serial ? And how would i know if it does support serial?

[@charleschatterley7947]

New to the tuning world. Would I ever need 2 widebands? Or can all this be done with just the single wideband setup? If a single will do, is there a preference on which bank to put it on?

[@mrjowls9814]

Hey there dude! I bought an AEM 30-0334 wideband before I realized that pre 2007 vehicles dont support the can bus interface. Will I be able to make this work as opposed to splicing my gauge into the hp pro link??

[@GoatRopeGarage]

I don't think it has a serial out, unfortunately

[@chrisbryant1657]

@@GoatRopeGarage So will your setup work on my '98 z28 with AEM 30-0300 x series WB, HPTuners version 2.2 (original serial interface), Windows 10 with USB 2.0 port? One of the 3 items listed in the description is no longer available on Amazon. I understand why I need the serial to usb adapter to connect HPTuners serial interface to USB port on my laptop. I'm not understanding what the other 2 items listed in the description are for.

[@danielsuehrstedt5396]

Hey man, I'm trying to tune a 3800SC that's in the back of my fiero. I'm using HP tuners, and have a AEM 4110. I have a db9 cable wired into the gauge, and the same db9 to USB cables I saw was used in the KZbin video about this. I've checked the drivers, and shut down the computer and started it up with the hp tuner and wodebamd connected. Even with all this, as soon as I hit log my wodeband dissappear. Any other ideas?! BTW love the videos, have helped alot!

[@charlesmeyer3743]

Do you write tunes for anyone? Could use some help writing a tune for a lq4 6.0 with a chaoppacabra cam

[@Therace-qz8ik]

May have just answered my own question but still want to verify. What i stated earlier did not work. I ended up making a user defined math that subtracted the .48 error from lambda labeled (tailpipe EQErr) and all lines up. Please if there is any better ideas let me know

[@GoatRopeGarage]

Yeah, that's a bit leaner than I would expect to see but if you're testing at idle you're still getting air on it most likely.

[@Therace-qz8ik]

Goat Rope Garage well its reading consistently lean. I just did for comparison today another silverado with no cats and it reads the same. So somehow or another i have my scale not correct? With the user defined math where it subtracts .48 on both trucks gets it near 0 err.
