For anyone wondering about the fuse, this only applies to '90-'93 models
yes we want a video about wideband
"this metal plate will cut you like a gangster in a bad mood" lol made my day
I have to say, this channel is going to be one of the next to blow up! Your videos are so good, I cant believe you don't have more subscribers yet.
***** Thanks for the compliments! I just want to get good info out there and help the community. Thanks for the support and stay tuned :) (No pun intended)
@@TheCarPassionChannel 5 years later and I see it mentioned by all sorts of huge car channels

I gotta thank you, this and your wideband install video were the two biggest helps I had when installing a wideband and an MS3 in my 1994 Miata w/ AC.
For anyone else who may be wondering how you "combine" these two videos (if you're trying to install both at once), when it comes to the new wideband sensor, I wired my wideband's digital output through a CAN module and inputted that into the options plug on my ECU AND also wired the analog wideband output into the stock O2 plug (aka, also to the new ECU, through the stock harness). This was on the advice of an experienced engine builder/spec miata builder I've been working with.
Also, for cars with air conditioning, the grommets he uses in the video are not available, and there's a lot of equipment mounted behind the glovebox door, but I still successfully drilled a new hole through the firewall and routed the MAP line through a grommet in the new hole (when you remove the glovebox door, there's a space where you can fit your hand over and between the A/C components and reach the firewall...that's the safe space to drill, as high as you can, to get up and over the rubber matting and sound deadening that lines the interior of the firewall).
Lastly, on 1994+ cars, the ECU is not in the passenger footwell, but is mounted on the bulkhead behind the passenger seat. It doesn't change the install very much, you'll just need to plan on a few extra feet of vacuum line.
Thanks again TheCarPassionChannel, and keep it up!
8:30 greg has his plug upside down. If you look at a wiring diagram its pin 2 and pin 7. Pin 2 is earth and 7 is the signal to the ecu for the iat sensor. But as he said, theres no polarity on the sensor so it doesnt matter. Might help for diagnostics though if anyone needs it
keep these coming, i'm really interested in grabbing an NA to start wrenching on with a family friend that has a v8 swapped NA, looking to do low boost for now and really wanted to get more of a mental hold on how mega squirt's software was like. This helped me get the ball rolling, thanks!
I just got MS3 for my '92. I'll be rewatching all of your MegaSquirt Videos while I wait for it to arrive. This is starting my turbo build, so I'm sure I'll be rewatching all of Broke&Boosted. Heck, maybe a few times before it's all finished. Thanks for all of these great videos on this info.
How did you get on?
This might help a few people out when setting up the IAT. My tubing was cast, and it was tough to find some to install the IAT bung due to lack of a proper welder. Instead I chose the method here to use the 9/16 drill bit on drill press then used the NPT tap as recommended. The helpful part is Homedepot, Lowes, and Pep-Boys all didnt have the size recommended in the video. I went to Harbor Freight for the press, the bits, and tap kit (assuming you dont have one). That got the job done, and this video was super helpful. Cheers!
Hi from germany! If you are running 95 octane fuel in your Miata, you can put youtär Ignition timing to 14 degrees before tdc. There will be no knocking or uncontolled auto ignition by the fuel. I tried it up to 16 degrees before tdc and still no knocking. I put it back to 14 degrees, so there is no stress for the engine. It runs a bit better with this setup. Most of the Mx5 enthusiasts in germany are running it at 14 degrees. Nice vids man. I watch it every week.
Fuelfoxx Thanks for watching! Many people here in the U.S. set their CAS to 14 degrees here as well, even though we only have 91 or 93 octane depending on the state. When you adjust your CAS you're setting your idle timing, but you shift your whole timing map even on a stock ECU. So if your stock timing is 10 degrees, you may be at 28 degrees at full throttle, 32 degrees while cruising, etc. But when you clock your CAS to be 14 degrees at idle, you're now 32 degrees at full throttle and 36 degrees cruising. (These are just examples I'm not sure exactly what the stock map looks like) so it may be better in some areas and worse in others. But since you're only talking about a few degrees, it will likely be beneficial everywhere, since the stock map is designed to run on 87 octane (at least here in the U.S.).
literally from the time i get off work to the time i go to bed, i am watching your videos, thank you for being so informative and helpful, great stuff man keep it up
Thank you thank you thank you!! Someone else suggested it, but a coilover installation guide (specifically for an NA Miata) could be a great video in the future!
React Your welcome your welcome your welcome!! I'm actually thinking about doing a coilover video next week.
been looking for something like this for like a month to get ready and this just popped up as the first video on my homepage
wideband wideband! haha I love your videos man! keep us happy:)
Thanks for these videos man. There really useful and very detailed. Very helpful to me I'm doing a turbocharged NB mx5 and I've been slowly buying parts until I have everything I need I was confused about what engine management to use but after loads of research on forums and websites I've decided mega squirt these videos helped me make up my mind. I imagine the installs will be similar very slight differences as mine is a NB. Thanks again.
Please do fuel map tuning & wideband install! Thank's for making this informing videos for us!
This video makes it look easy. Thanks so much for taking the time to make this!
I've been looking for a video like this for awhile. Seems like its really easy to use mega squirt for a beginner.
Need more tutorials! These are super helpful
I've watched your whole video just for the last 30 seconds. Although I have totally different car and different engine from different continent than your engine and car. But bro,,, thanks a lottttttttttt... your video really helped
this has helped me with a similar set up for my bike throttle bodied 93 mx5 1.6. cheers from the UK!!
I just bought a miata =) I like watching your videos !!! and haggared garage !
I just picked up a Ms2 and an Innovate wide band. I was making 160hp to the wheels un-tuned, with an m45 blower on my 1.8. Can't wait to see what some proper management does for it.
+Bryan Murphy You should pick up some good power on the dyno.
Thanks. I hope so.
Thanks for your videos, you have a great way of breaking these things down so I can go in with confidence. I video I would like to see is a mild engine bay tuck. (Tuck wires, delete charcoal canister, coolant over flow, etc.) Thanks again
Thanks for the vid... I really needed actual footage of the tunerstudio screen as you did to direct me.. I'm just more of a visual guy..thanks again bro!!!!
Wideband video! pls
So glad i stumbled upon your channel! just got my mspnp2 for my 94 miata, but won't be installing it until i pick up a wideband (also glad to find you have a install vid for wideband!) can't wait to see your basic fuel map tuning vid
+Jimmy wu Welcome!
Another awesome video bro, thanks for taking your time explaining how to install mega squirt and a very easy way to understand.
14:09 more precisely that is the MAIN relay, that powers a lot of stuff including injectors, sensors, ignition, and ALSO the fuel pump relay (that is under the dash!)
Nice video - thanks. I'm adding a Rotrex to my 2001 NB and have a MS3 built by Rev that I'm installing along with it.
Man, your videos are detailed. I LOVE it. A wideband installation would be cool too. (:
Thanks for the video man! I'll be re-watching this when I get my MS for my 240SX.
An install video for the wideband would be great. Awesome videos btw. Keep up the good work.
im not ready for megaquirt
Subscribed ... great video. Realistic disclaimer too! Love it!
If you wanna do an AFR gauge install video, that would be sweet.
Thank you for this video, megasquirt has confused me more than any other aftermarket ecu maker
This is one of the best expaination to how to setup for mega squirt! good job!
Have you done a roll bar and aftermarket seat install vid yet? If not could you? Thanks in advance, I really appreciate what you do. You're saving a lot of us Miata enthusiasts money, time, and frustration. Peace
Awesome video and info! Thanks for posting all of these. I'm looking at buying a na Miata soon and will also be looking to turbo it with megasquirt! Subscribed sir!
Any vids concerning the specifics of turboing an mx5 would be great bro, injectors, wideband, turbo/manifold choice, list goes on, even just vids with your views on certain things, its refreshing to see a video about this stuff vs reading 100s of forum pages
Dj SkFk I'd recommend checking out my two videos "How to Turbo Your Miata" and "Turbo Miata Parts Overview and Hard Canyon Run" I talk about a lot of the parts I have on my car and give info about the turbo conversion process. Feel free to ask any specific questions you might have.
Wideband video would be awesome man! And so would a basic fuel map set up! Thanks
Great video, thanks for the info! Found the rain oddly relaxing :D
Great Video. It is good to mention that NB's don't require the IAT install, they already got one :)
yossi126 But isn't it part of the MAF? Even though their MAF has better flow than the AFM of the 1.6, you can still remove it and convert to MAP. It makes it easier to get creative with your intake routing and not worry about where you're going to place the MAF.
I just found your channel and I must say your videos are VERY well done! You are very good at teaching each subject.
I don't even own a Miata, but find your vid's compelling.
keep up the good work!
hey man I watch your videos constantly lol I have a 96 miata and purchased everything but my yellow top rx8 injectors and my megasquirt pnp2. I plan on trying to tune it myself because I literally can't find a shop in ohio that tunes off megasquirt
+Matthew Callihan Read up! I learned everything from Miataturbo(dot)net, messing with all the settings that I felt comfortable with, and of course talking to tuners that know a lot more than me!
Great info for the novice ,Nice video..excelent job . would be nice to see vids like this for other engine configurations and brands of ecu
thanks for sharing this great video, I'm Japanese and there's basically no informative one in Japanese. watching a movie is way quicker and better to understand than reading tons.
Your videos are super helpful and really clear up a lot of confusion, keep it up! +subscribed
@TheCarPassionChannel alright so got a day 2 question for you: where do you go to learn specific stuff? Megasquirt docs are pretty thin, not very deep, nor very car specific. Tuner Studio docs seem nonexistent. Searching forums always comes up with random other people's cars/setups and not basic info about what the settings actually do and what the concepts are.
If you were wondering "what does XYZ setting actually do?" what would you do? And when searching, what keywords do you usually add in to get to the right type of content for Miata+MegaSquirt+TunerStudio? I thought I was good with Google, but damn...
Thanks! Your content rulez!
yes finally wideband install would be appreciated (:
Great video! I'd like to see a video on the tuning capabilities and the data logging.
It would be great if you did a wideband sensor video or tuning for injector change.
This was great, I have been reading MT.net a lot to prep for my MS install and this video was the perfect compliment.
You seem like an experienced driver, do you think you could do a video introducing some driving techniques?
Christopher Airikka That's a good idea! I've been racing autocross for about 7 years so I could definitely make a beginner friendly driving techniques video.
I second that! That would be an awesome idea for a video!
Great video man, Its nice to see someone actually show it rather than just reading it and assuming a few things. I would love to see a wideband video, or at least more explanation on how you wired it into your MS and if your gauge is straight off the wideband or from your MS. Im guessing its its getting its data from MS.
Joseph Conley I may not do a wideband video for a while, but hopefully I can answer your question. A wideband o2 is a standalone system. You can install just a wideband by itself in the car and it will function just fine. Widebands have a signal wire that comes from the gauge in most cases, which is just a wire that outputs what the gauge is seeing. That wire goes into MS. So Megasquirt is getting its data from the wideband. That's why you need a wideband to have Megasquirt, otherwise you'll have no idea what your AFR's are.
TheCarPassionChannel I understand that, and to my understanding some widebands have multiple wires out. I was curious how yours was currently wired. Wideband -> MS -> Gauge? Either way, your videos have been very informative.
Joseph Conley My wideband (Innovate MTX-L) is a self contained unit. The sensor and gauge are all one package, you can hook your laptop up to the gauge itself to set preferences. The gauge then has 2 output wires, a narrowband and a wideband output. You just connect the wideband output to MS and you're rolling!
Awesome, thanks man.
Wideband Video! Also great great job on the videos man. Going to be getting a miata soon and cant to do some "general maintenance" ;)
Great videos man! Super helpful and well put together. I'm currently doing a lot of research for my own turbo install on my 97. So any more videos from the post-hardware install to getting the car to the dyno would be extremely helpful.
Cheers!
Loopable161 Honestly once you can start and drive the car on the base map, you could bring it to a tuner. A lot of people like to do some mild street tuning beforehand, I will probably cover some basics of that in the future.
TheCarPassionChannel Awesome, any Megasquirt tuning would be helpful.
I was wondering how to adjust the fueling tables. if you can make a video that would be awesome.
Great channel, thanks for your time.
a while ago i stumbled upon one of your videos and to be honest i really appreciate your style and twist of the way you make videos. I seriously went out and bought a cheap 93 miata so that i could learn from you and be able to relate more. Keep the content up! I hope these videos can lead to a bitchin career for you! - chris
Larger injector video would be great!
More on megasquirt basics please Greg🤞
Man I wanna see everything what u have please :) maps, injectors, wideband... i just starts working on my 97 mx5 and I`m learning a lot from You. Thank You
+ToFast2beSlow Awesome man, gonna try to keep the videos coming. Next one is up Tuesday morning.
Coilovers, wideband, and more tuning stuff!
Thank you for video! You helped us to connect!
Awesome video gonna order my ecu soon! Wideband video please don't know how to install one I'm a noob.
Great video! Keep it coming +1 for wideband instal!
Please make a wideband video, I'm looking to install ms in my 91 soon, and the wideband in the only thing I'm no confident with
I had a b6a1 ecu in my little mazda pickup, it was inside the dash and I had to take basically the entire dash out to get to the ecu... Luckily I had to take the dash out anyway so it wasn't a big deal
Would love to see a video on basic fuel mapping please! :)
my MAF is discontinued... looks like this is a good option for me! Sweet!
Can you make more videos about maping/Built map on mega squirt etc etc im going turbo on my BMW M50 is a diferent car but the basics are the same and i would love to learn more and more about megasquirt and turbos, I see you got a BMW on you front yard :D
he has a 328is which is the m52 if I'm correct. got out of the e36 game for miatas a while back. they handle as well so good find brother.
Hey man, this video is great, but for us that suck with engine electronics/tuning a full in depth video would be better. I feel like doing it in full depth would be more beneficial :D thanks for the videos man, they are very helpful.
Jordan Wilbanks I feel like this was a pretty in-depth install, what kind of things are you talking about? If you're not familiar with the engine bay, I definitely wouldn't recommend installing MS yet. Start out with routine maintenance items like spark plug wires and air filter change. You'll gradually work your way up over time.
I have been re-watching, and its getting more and more clear. Thanks for posting the video man. Keep the great content up!
What do you do about your Smog check. Does the removal of the MAF = auto fail or are you allowed because of the Turbo mod?
Fuel map and injectors man.👌
Can you make a video on how to double clutch? I have been granny shifting and am worried because i know i SHOULD be double clutching. Thanks bro!
Double clutching isn't necessary for newer cars with synchro'd transmissions, like miatas.
Super cool. Thank you, man!
Great video bro. Can we please get that wideband video it would really mean alot. Thank You!
This is an awesome video. Thanks man.
You should do a video showing the advantages of turbocharging over supercharging
***** I love debating about this. Although to turn it into an entertaining video will definitely take some creativity!
I also would like a basic video on the next step after all your basic stuff is configured, could you make a step by step video for setting a fuel map, then how to adding timing in?
You should make a video on installing a wideband
very informative!
Thanks! Awesome videos
Amazing video thank you for your sharing your experience with us.
How many models mega square ecu, what the difference between.
For normal use not performance only to upgrade old ignition and fuel system for more reliable like.
D jetronic system mercedes v8.
Because no more parts available and not cheap to restore all systems.
What the easy ecu can used to upgrade this kind of system if not mega square, if I go for Ms ecu which model the best to my project.
Waiting any help or guide.
Best regards,
it's a t3 turbo with wastegate. also I want to put an intercooler later on .I'm new to this so I'm trying to do its slowly .
+Anthony Diaz So no wideband?
Wideband soon please. Plan on installing this and need some instruction.
Yes I would like a video on wideband
Can you do some tuning videos? How to use tuner studio, and maps?
I wish you'd make a video on the universal megasquirt 2 and the installation process
perfect video, thanks
Great video. Your channel makes it very tempting to sell my BMW and do a Miata turbo build.
Luca Car Mods You wouldn't regret it!
Please do a wideband video.
Awesome Man.
Great work on the video, would love to see wide-ban install
David Greenfield Search out "broke & boosted ep2" already did it 👍
Thanks for your videos, very informative, but I'm the person that always have the difficult questions.
Everything that you explain is understandable but I'm primarily looking for the way the megasquirt 2 v3.0… is connected to drive coil packs with stock igniters can you touch on that.
Can you provide a screen shot of the ignition wheel decoder section.
If this is hard to understand. Maybe I'll give you my specific question.
Wideband Install YES PLEASE!!!!
+Hollis Whitehead Next video.
Should unplug that wide band during all the setup of TS. Don’t leave it hot in no air flow.
Good vid man do one on map.ing the car
Wideband install! Also, which one to get, what the options are...
Please make a video on how to install a wide band
