This SpeedyEFI installation is going great. Next video is installing the hardware, calibrating all the sensors, and the first start in the new ECU! Let me know if you have any questions
Thanks for the video, just got my kit and will be installing next week when my throttle body gasket are in, your videos are one of the best I can find anywhere, thanks again and pls keep up the good work, cant wait to see how much power when you are all finished with ur na
You’re welcome, I’m glad it helped you out! Have fun with your kit. The ECU alone ads a fair bit of power (~5-8, according to SpeedyEFI’s owners). Right now I’m running low boost on the car (~4 psi) but it still feels quick compared to stock. Once I sort out a few more things I’ll start turning it up. Enjoy!
Love the content. Just bought my Speedy EFI Ecu! I’ve used your videos countless times when I do a project on my Miata. Keep up the awesome work! Also didn’t even know there was a cheap alternative to mega squirt lol
Thank you! I was surprised to stumble upon SpeedyEFI as well, and so far I see no reason to go with a MS over this. Best of luck on your projects, let me know if there’s anything else you’d like to see on the channel!
@@CashedOutCars how well is the unit holding up? Have you had any issues with it? I’m about to install one and use your videos to get it up and running.
I had one board fail on me, but that was due to a small batch of boards that had a manufacturing issue with the 5V regulator. It’s since been fixed, and SpeedyEFI replaced it under warranty for free. Other than that, it’s been great
The ECU wouldn’t start the car, but the car would crank since the starter isn’t ECU controlled. Also, if I had a USB to plug in the ECU to supply power to it, it would work. Final check was to remove the board from the case, and see the burnt regulator
Hey man! Just have a few questions about the ECU: 1. Do you regret going speedyefi/ do you wish you went megasquirt if the budget allowed? 2. Since speedyefi uses tuner studio like megasquirt are they basically the same? And does the speedyefi support the auto tune option of tuner studio like megasquirt? 3. Have you had any complications or problems with the ECU thus far? 4. What are some things that megasquirt has that speedyefi doesn’t? And what are some things you feel megasquirt does better than speedyefi? 5. What do you like and dislike about this ECU? Thanks in advance for the help!
Hey! I have no regrets with the SpeedyEFI. There's really no features that this ECU hasn't had that I've wanted. The MS3 has a few additional features, but I'll let you do your research on the differences. They tune nearly identically and both can use autotune, I have videos on my tuning process on the channel. I have no dislikes about the Speedy. In my opinion if you buy a MS you're buying it for the name, not necessarily the product!
Im having issues with a low idle which wasnt apparent before I turbo'd and somewhat tuned the car. Any ideas on where to start first? Its hard to troubleshoot because it wont idle unless I have throttle pressed.
If it's a light press of the throttle that's required, it sounds like it needs more air. You can open your screw on the throttle body to open the butterfly a bit, or make sure your IAC valve is working properly
Man I'm so sceptical on getting this for my nb I'll have money in 2 days for it and I just wanna know what megasquirt and speedy efi have in common and what is different. Like does it have overboost protection like ms their website doesn't give as much information as I'd like. Also I have not seen not one or anyone on forums or on youtube using speedy efi for nb are they new and should I worry about it for malfunction internals
@@Thatmiata_doe just ordered it I'll probably post videos since I don't see any on RUclips or forums for 99-00 nbs👍 might get a lot of views and help some brothas out
Yes it does have overboost protection if you set it up! I have a video on how to do it in my channel. There aren't as many NBs out there running them because its a nearly brand new kit for them!
I don’t know if you’d be able to help because it could be user error or something else, but I just uploaded my tune to my speedyefi and the coolant and air temp gauges are red as if it’s over heating but it’s not plugged into the car. I saw your gauges reading 0 for both values, any reason why this is happening you think?
Until the ECU is plugged into the car and your ignition is on the gauges won’t read accurately! You’ll also need to calibrate the sensors to ensure you get proper readings. Good luck!
Hi I have a miata NA 1.6. 1990 I have installed a 30-0300 x-series wideband 450cc injectors end a speeduino PnP . the car works fine, I just have to keep the laptop connected the engine stops if I do not use the laptop it looks like it's losing ignition because dashbord clock not working when does that after it stops it starts very hard. but it works at only idle if I want to leave the engine dies again can be the sensor on the clutch pedal because I can't use the option to decelerate fuel cut off. if I activate it, it does the same thing as with the laptop disconnected I want to put a supercharger but I can't make the car work. if you can help me thanks
Desperate Question! I have a 91 with a 1.8 swap and I plan to use a speedyefi, do I get a 91 ecu or a 94? This is literally the only thing stopping me haha
I know this is a mildly stupid question but can I make this work with a Lexus if I run my own wiring and plugs? I only ask because it looks like there’s a lot of Miata support and wanted to see if I could simply use it to run. Lexus SC400
They do make a kit that’s made to wire up to other engines. I think you’ll need to confirm that they could run a 6-cylinder though. You could message SpeedyEFI and they’ll help you out, good luck!
When i get to 5:45 it says ‘current status: upload speeduino failed’ apparently because ‘can’t open device COM3’ access is denied... how can i fix that? pls help!
CashedOutCars Oh wait actually, i haven’t no idea what i did but it’s starting to upload now, haha thanks tho. i have been watching your series and am basically following everything!
This is the spreadsheet of everything used for the turbo build. As for other parts I usually search around on eBay and Amazon first if it's not stocked locally at an autoparts store docs.google.com/spreadsheets/d/1utxt6RxZKm9tagEljE45dF8TdDBuiJMvdeBqbGWcQg0/edit?usp=sharing
Nice video for Speeduino, but you can be more creative and stop copy the TheCarPassionChannel "everything" - The ultimate guide , "broke and boosted" ... even the topics of every video from the playlist.
I’ve been doing “complete” and “ultimate” guides for quite some time. You’ll find this across most successful RUclips channels, including some of my other channels started long before this one. Greg and I spoke about the name before I put the series out, and he was very enthusiastic about it being called 2Broke2Boosted. It’s an updated budget build that uses full standalone tech, and again shows the world that stuff like this can be done on the cheap. Due to the nature of turboing any car, of course the episode structure is similar. I appreciate you taking the time to comment!
@@CashedOutCars thanks for the reply. Actually I found it because I was searching for installation video for speeduino and your video is actually helpful. Just the naming was too similar, but it’s cool that you spoke with Greg about it

I hope your videos will be a great tutorial on how to turbo Miata :) Thank you.
They certainly will be! It’ll be a complete guide on how to turbo a Miata on a budget by the time the video series is done!

Do you know if i can use a Chromebook or does it have to be a windows or mac
sadly i tried, it doesn’t work so i had to dig up an old windows computer.
I need help I have a Speedy EFI and I want to know how to make a program for it
Greetings I am having problems with the ignition of my speedy you think you can help
Cool info :), how can you get the iginition and injector timing from your original Mazda 1993 ? OBD ? Thanks
Timing that works well for a stock Miata is build into the base map!
"Ardoo-Weeno" lol
brother should my air inlet gauge and coolant temp be on red?
Quick question do you need the throttle position sensor for the 1.8 miata my kit didn’t come with one
While I haven't installed one on a NA8, it doesn't look like you need a different TPS. The built in one is probably a variable TPS, so you're okay!
Im having issues with a low idle which wasnt apparent before I turbo'd and somewhat tuned the car. Any ideas on where to start first? Its hard to troubleshoot because it wont idle unless I have throttle pressed.
If it's a light press of the throttle that's required, it sounds like it needs more air. You can open your screw on the throttle body to open the butterfly a bit, or make sure your IAC valve is working properly
Does that ecu fit on my 1997 1.8 na miata?
Does this ecu work for later models of the Mazda Miata like the nb models or does it only work on the na models
Look it up, but they sell different ecu's for different generations, they have them in stock right now for 99-00
Man I'm so sceptical on getting this for my nb I'll have money in 2 days for it and I just wanna know what megasquirt and speedy efi have in common and what is different.

I want to put a supercharger but I can't make the car work. if you can help me thanks
Hi, my first question is are you unplugging the laptop while the car is already running? If you are theres a good chance that’s what’s killing it
it does the same thing if I start it without a laptop connected
I’d data log it and post it in the SpeedyEFI troubleshooting and support group on Facebook. They’re very helpful over there!
Can you install this on a Honda Civic 98?
You can certainly wire them in! They won't be plug and play though
Desperate Question! I have a 91 with a 1.8 swap and I plan to use a speedyefi, do I get a 91 ecu or a 94? This is literally the only thing stopping me haha
You’ll need to find out which wiring harness was used, this will determine which ECU to get! Good luck!
@@CashedOutCarsso let’s say i had a 90 with a 1.8 and a 90 harness. i got the 89-93 ecu but wasn’t sure what tune to load in.. 89-93 or 94-96

@@CashedOutCars awesome. The SC400 is a V8 but it has batch fire injectors
Oh sweet! Yeah that’ll help you out. I thought those had 2JZs in them, shows you how much I know about Lexus! Happy holidays!
@@CashedOutCars you are right. But the SC300 has the 6 cyl 2j and the SC400 has the 8 cyl 1uz
When i get to 5:45 it says ‘current status: upload speeduino failed’ apparently because ‘can’t open device COM3’ access is denied... how can i fix that? pls help!
Are you sure your device is on COM3 and not on one of the other ports?
CashedOutCars it is the only port that shows up when uploading or even on the arduino port list
Gotcha. And you’re able to communicate with the arduino software through COM3?
CashedOutCars yep it reads “COM3 (Arduino Mega or Mega 2560)”
CashedOutCars Oh wait actually, i haven’t no idea what i did but it’s starting to upload now, haha thanks tho. i have been watching your series and am basically following everything!
