My Supercharged Mazda MX-5 Is Now Slower Than It Was Before
Edelbrock Mazda MX-5 Miata Supercharger - bit.ly/38MViPn

MX-5 Supercharger Install Video - • Supercharging My Budge...
The joy of project cars! After installing the Edelbrock Stage 1 supercharger kit on my 2016 Mazda Miata, the unfortunate news is that things are not working properly. The biggest problem is that at high RPM the car doesn't have any boost with the gas pedal to the floor. We'll examine the installation, data logs, hose routing, throttle body, bypass valve, bypass actuator, and supercharger to figure out what is causing the car to not produce any boost during certain situations.
A big thank you to Edelbrock and Fab9 for working with me on the issues and helping to sort out the car!

*Important Note:* A lot of folks saying "obviously the car needs to be tuned if you add a supercharger." If you watched the supercharger install video, you'd see the *very first thing I did* was flash the ECU with the supplied calibration file to support the supercharger/boost/etc (the tune). If parts of this video do not seem clear, I'd recommend watching the installation video - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yOQtbwyFV4g.html

@typhoon4645 4 года назад

So this could mean Edelbrock's tune has an issue? Did you contact them about that? Or as an experiment you could put the Edelbrock tune back and see if the issue repeats. Its your car and your call Jason.

@EchoOfGecko 4 года назад

@@typhoon4645 I'm curious about that as well. Seems like maybe the original flash failed, or maybe the wrong file was uploaded to the ECU? Seems like too many disparate issues for the tune file from Edelbrock to have out of the box... surely it must have been the factory tune.

@slobdog21 4 года назад

If you flash the car first and then disconnect the battery to perform the work wouldn't you lose the tune and it would return to stock? I thought it quite strange to flash the car FIRST but maybe flashes remain after disconnect.

Fantastic video, I like Jason's humility, and consider that a life lesson to be emulated. I am awed by people that take on projects like these, but I realize that he has created a job for himself that allows him to learn, so we can learn. And he doesn't curse or get angry when he faces a problem, he just goes through the list of possibilities. Really, he made no error, the tuning done before the supercharger was installed didn't work to change the mapping of the throttle body response, it needed the tune repeated, or a different tune ( I don't remember which). But in the end, he downplays the satisfaction of having taken on such a project, and now having his vehicle working right. BRAVO. Lets face it, most people reviewing cars look at them, describe them, drive them and tell us how they feel, they feed us the pablum about the technology put into them described by the press releases. Jason does it, but then he takes the time to show us what that technology is, how it work. On a white board. NO BETTER CHANNEL ON YOU TUBE for learning about cars, and that includes how they work, and the compromises of every design.

@calebshonk5838 4 года назад

Most project-car videos only show the beginning, install and the perfect end result. They rarely delve much into the difficulties that come up during the installation and even less into the actual problem-solving process when something doesn't go to plan. In my experience, things rarely go to plan and most installs are not absolutely perfect (though functionally correct). Personally, I would rather see the process of diagnosing an actual problem than just the shiny end result. I thought this video was informative and helpful and I'm glad you took the time to really explain the problem and your line of thinking.

@BobPegram 4 года назад

I personally find it very interesting to see what the problem is and then the fix. Where did you get your initial SC tune from, Eldelbrock or the guy who supplied the working tune? Secondly, why were you blind to the idea of the throttle being controlled wrongly until the tune supplier mentioned it? You already knew that the Miata throttle is "by wire" rather than a direct connection from your foot on the gas pedal. My 7 yo Subaru has an annoying tip in because it goes full throttle from a dead stop. Darn hard to modulate! There is a fix but I haven't looked recently to see if someone made it EZ to do.

I watch these videos because I want to learn about tech and because it's such a joy to follow a skilled tech as he takes apart and understands a problem. It's not nearly as interesting to watch someone throw a dart and scream "GOAAAL." The best parts of my job are when I have to solve a problem where the obvious solutions won't work. It takes a lovely mix of technical understanding and creative thinking to analyze a difficult problem and build a solution. For example, sometimes the best solution bypasses the underlying problem in a way the original designer didn't expect. A good dart thrower identifies where to quickly score points. A skilled engineer adapts to the situation, uses what she finds, creates a solution, and can build it.

I was in the camp of boost leak when I started watching...usually such low AFR's mean loss of metered air somewhere and coming it at higher RPM was suspecting a faster ramp up of boost was "opening" the leak, although that's more common to the characteristics of a turbocharger than a supercharger. Now what I'm curious about is what was actually wrong with the tune that kept the throttle open when accelerating from lower RPM. I can't think of anything in the typical tables that would cause the throttle to behave that way. (Did my own tuning on my former Mazdaspeed 3 with Cobb Accessport)

"What position is your throttle?" "Well duh, my foots all the way to th...... DOH!!!" Great, brilliant, amazing video. Vehicle diagnostics is a pain and the value of a good mechanic is so under appreciated at times, number of O2 sensors I have seen replaced for a manifold leak where someone checked their air filter and left a vac line off is crazy... They were only just introducing throttle by wire on mass in Aus when I left mechanics, can only imagine how few people would have the skills to diagnose this over the phone. Hope you brought that bloke a 6 pack ;) I had a L67 with similar charging setup and racked my brain the whole time video ran and was stumped, thought it has to be an air flow/pressure issue possibly caused by tune and even focused on the throttle and seen it was electronic but it didn't click until you said he asked what the TP was >.

@volvo09 4 года назад

Yup, and the amount of customer frustration and money that's wasted by just replacing parts (like o2 sensors and even ecu's) without first figuring out WHY that code is triggered is so common. A scenario like throwing 3 o2's on a car, a couple other expensive parts, and a computer when looking at the data shows wildly off fuel trims from some other issue. Data is key.

@zachyoung5598 4 года назад

Your comment about the blame game and just concentrating on the solution is spot on, if we had this approach for all the things and problems we find and even how we treat each other, things would be a lot different.

Please ignore the "get to the driving/dyno" comments... There are loads of videos on this platform you can go watch of cars making noise and burning tires. This is an engineering education channel, as the name makes pretty clear, and that's what I come here for. As an ex-engineer turned mechanic, this is gold content for me, and I'm obviously not alone. Maybe the comments don't reflect that very well, because comments are usually more of a way to complain about stuff than point out the good. So if I may speak for myself and people like me: We like figuring things out, seeing machines/technology working (or not), looking at spreadsheets to understand what happens where we can't see, and fixing issues or optimizing things. The graph that comes out of the dyno is a lot more exciting to me than watching the test happen. I wish there was more supercharging Miatas involved in my day job, so for me this is basically mechanic escapist entertainment that is also educational. It's freakin' great.

Thank you for going through the diagnostic issue to the end. This is what I do for a living and some people think it's magic or the mechanic is automatically supposed to know what is wrong as soon as they tell you the issue, give you the "Code" or hand you the keys. Very clearly described step by step and no bs results. Sometimes as a mechanic I will be watching one of these videos and say "Hey wait! That's not right!". And some guys end with results like "It is what it is". But this was clearly diagnosed and you used all the tools available to you and one of the best tools is not being to proud to ask questions. Questions always trigger a new thought pattern even if the answer you get wasn't correct. I don't remember when I subscribed to your channel but I haven't seen one, I didn't like.

@toddpercox9017 4 года назад

The accelerator to throttle position sensor parameters shouldn’t change by adding boost. They have an A and B accelerator position sensor and an A and B throttle position sensor. One usually starts at 0v and the other starts at 5v. One should rise and one should drop in voltage, with pedal and throttle position. So technically both sensors should read 2.5v at approximately 50% throttle. Love the channel, a lot of great information, keep it up!

@geoffreyveale7715 4 года назад

Unfortunately the position the throttle only uses the throttle pedal as one of many inputs and the computer decides where the throttle should be. Modern cars are very complicated beasts in this regard and many inputs could limit the throttle, even if you have the pedal floored. A simple example is that if you mash both accelerator pedal and the brake the computer should decide to give zero throttle which is the safe decision. In a similar way throttle could be limited by engine temperature, knock sensor, O2 sensor, vehicle speed etc. These systems are designed to protect the engine and give good fuel economy, good driveability, and good power when needed. Adding a supercharger can mess this finely tuned system up as Jason found out.

It still can take away some power by changing the Ignition Timing, Fuel Injection Length etc. That's one thing the ECU can do in a cable-actuated throttle to take away power. For example if your knock sensor is detecting slight knock you ECU usually changes your ignition timing to get back to stable combustion levels.

TLDR: if you install a supercharger(or any major engine modifications), GET A TUNE. Jason, I love your video. It has taught me so much about all the things I ever wonder about cars and engines. I wanted to comment 1 minute into the video but I figured to give you the benefit of the doubt and watched till your conclusion. As a Subaru owner and an active member on car modding community, it’s basic knowledge. If you mod the engine, especially for power, GET A TUNE. I’m glad you figured it out in the end but I am honestly surprised it wasn’t obvious for you. Regardless great video and I’m sure good learning lessons for many. But with modern ECU controlled vehicle tuning is the NO.1 thing. Even for stock no modification car, tuning for local gas quality and proper altitude will give you better gain and allows the car to run properly. It’s impossible for factory tune to work on the same car driven high Colorado and sea level Florida.
