WOW! I must've watched a dozen videos installing this gauge and you're the first person to actually go over the most important part...the wiring!! I cannot thank you enough. Your 9 minute video would have saved me 4 hours of research. YOU ROCK!!!
I think I must have spent a good 2 hours scouring the internet for wiring information on this and here you are, as below I cant believe there isn't more like this out there! you're a start ! Time for me to subscribe and like every one of your videos !
Thanks Daniel. Great to hear. Despite the overwhelmingly positive comments for this video I don't know why it's taking people so long to find it. TH-cam needs to up it's game and get it ranked higher!!
Thank you for this as well. So in depth. Feels like i spent the whole day watching hours of vague instructions from multiple other people just to be lead to this extremely informative and in depth tutorial.
Thank you for this! The wiring on my brothers turbo miata build was giving me a huge headache and the Chilton's manual plus the AEM instructions did very little to help (thanks Chilton for only showing the wiring going into the ECU but giving no explanation as to what the wires do once they get there). I'll be sure to give you a shoutout when my video goes live you're a lifesaver!
I just installed the same gauge in my 2001, and this video was very helpful. Thanks in particular for showing the wiring of the brown and white wires to the factory harness. Even though the wire colors on my car are different (2 whites instead of 2 blacks, black and gray instead of blue and white), fortunately the pins were in the same places on the plug you so clearly showed.
Great to hear. It took a bit of research to put this video together, there's a lot of information dotted around on the internet but not all in one place!
Great help, thank you! I got a CEL for my Toyota due to the heater circuit no longer being connected via the stock lambda connector. Short term fix is to wire the old lambda heating circuit back in.
Great video very clear will keep up with the rest of the build big help to my build aswel as ecus and wiring aren't my area of expertise t as a previous comment says all videos tend to be for na mx5 ,so an nbfl with vvt. Is good to see
Hi there, great video, was just wondering which wire you attach to the signal wires from the ecu, for example, WBO Vs, WBO Ip, WBO Rcal etc Many thanks
Thanks but aren't you on like a strict budget? Why did you go and get an expensive wideband? Couldn't you just get something like an exhaust gas temperature sensor. Then you tune according to the temperature?
AEM X Series is on the cheap end of widebands! Especially if you get one 2nd hand like I did & for ECU tuning purposes it's essential. You could not tune solely off the temperature of the exhaust.
You can do a fresh air calibration via the gauge if you really want to, but these 4.9 sensors are pre calibrated so it's not necessary. Just bung it in the pipe and go.
Yes it'll work fine on the basemap. When you install the wideband you'll have to change the lambda settings in MEITE. You can see that in the next video 👍🏻
@@FastRust Yeah mate, using the same gauge and have an NB1! Been trying to figure out if I could get signal and signal ground from the stock harness and you explained it so well!
Thanks, glad it helped! Yes signal and s/ground at the plug. There is a 12v switched live there as well (for the sensor heater) but I keep reading people having issues with doing it this way, hence cig lighter 👍🏻
hey man i used this video to put mine in and im having some problems with it. i did it the exact same way however my nb has 2 o2 sensors, so i used the on the exhaust manifold (before the cat). the guage works, however im getting a code P1135) pretty sure my ecu is not getting a reading from the wideband. the car runs rough and very lean. I'm still on a stock ecu, any help will be appreciated
You can't use this gauge with stock ECU as it doesn't have narrowband emulation. You need to get a gauge that does or use a standalone ECU like the ME221
If you need to know how to calibrate the AFR gauge within the ECU software, check out this video : th-cam.com/video/6mUXCusK7X8/w-d-xo.html

Cheers Matt. It takes a fair bit of effort to put these videos together so comments like yours are very much appreciated. Thanks.
@@FastRust Same opinion as SpeedWhomp420, This is a very easy and comprehensive video! Thank you so much mate!

You have been so helpful with my install. All the videos on TH-cam are the single wire from NA's!
Thanks Jordan. Glad to hear it.
Thank you for this as well. So in depth. Feels like i spent the whole day watching hours of vague instructions from multiple other people just to be lead to this extremely informative and in depth tutorial.
Thankyou 👍🏻 Tried to condense as much info as possible into one video and judging by the comments I succeeded!
Small channel but your presentation and delivery is really good - clear, concise and informative, makes it easy to follow. Keep it up.
Thanks a lot. Really appreciate that!

Awesome. Glad to hear this helped you out. Agree - not much info out there on how to wire these up properly.

You need to do anything with those 2 blacks? just leave alone?

This will be very useful when I come to install my aem wideband next week, thanks for the well detailed video 👍
Thanks. Glad to hear it 👍🏻
I watched this video too many times to finally understand how you basically split the wiring between two harnesses.
Most descriptive video on the internet 👍 just fitted mine today, Thank you.
Glad it helped with your install. Thankyou!
Stumbled across this series by accident… Bloody brilliant stuff mate! Now I want to buy an MX5 🤣
DUDE THANK YOU SO MUCH THIS VIDEO SAVED MY LIFE YOU ARE THE BEST

Great video and presentation. Very helpful 👍

Hi there, great video, was just wondering which wire you attach to the signal wires from the ecu, for example, WBO Vs, WBO Ip, WBO Rcal etc
Many thanks
I have a question about wiring the gauge to the ecm. My gauge was working before I connected the wires, now it won’t even turn on
Can I get the +12V from the same connector? I think that one of those black wires is positive when the ignition is on.
It is but I've heard multiple issues with getting 12v from there. Personally I'd avoid it.
@@FastRust True, I tried it and doesn't work. Connected to the cigarrete lighter! Thank you!
Thanks but aren't you on like a strict budget?
Why did you go and get an expensive wideband?
Couldn't you just get something like an exhaust gas temperature sensor. Then you tune according to the temperature?
AEM X Series is on the cheap end of widebands! Especially if you get one 2nd hand like I did & for ECU tuning purposes it's essential. You could not tune solely off the temperature of the exhaust.
Did you have to calibrate the gauge at all or was it precalibrated?
You can do a fresh air calibration via the gauge if you really want to, but these 4.9 sensors are pre calibrated so it's not necessary. Just bung it in the pipe and go.
can you get the car started before you swap out the old narrowband sensor with the me221 or is it needed for it to work
Yes it'll work fine on the basemap. When you install the wideband you'll have to change the lambda settings in MEITE. You can see that in the next video 👍🏻
Can you get power and ground for the guage from the black heating wires?
No. This has been tried but will cause issues.
Thank you so much for this video
No prob. Are you using the same gauge with Megasquirt?
@@FastRust Yeah mate, using the same gauge and have an NB1! Been trying to figure out if I could get signal and signal ground from the stock harness and you explained it so well!
Thanks, glad it helped! Yes signal and s/ground at the plug. There is a 12v switched live there as well (for the sensor heater) but I keep reading people having issues with doing it this way, hence cig lighter 👍🏻

You can't use this gauge with stock ECU as it doesn't have narrowband emulation. You need to get a gauge that does or use a standalone ECU like the ME221
Will this afr sensor+gauge work on a 96 miata with stock ecu ?
No, there's no narrowband emulation on this model. You could weld another bung in the exhaust and run it independently.
Can you hook up the ground to the ground for the cigarette lighter?
Probably. I just know from what I've read these units are fussy when it comes to ground location. Hence me going into the engine bay.
I hate to ask but would tapping into the stock ECU harness also apply to an NA 1.6?
Yes but from what I gather in the comments there's less wires to deal with on an NA. Might be worth a quick search before you start.
@@FastRust yep. Only one wire. I ground the brown wire to the block. Pretty straight forward. Thank you sm again
I can’t seem to get mine to work wiring it up the way u have
Tks pal.
