I clicked on this video honestly expecting some kind of ghetto shortcut, and my man hit me with textbook facts and a professional installation guide

Completely underrated channel, nothing but quality from you. Please continue to produce grade A content, love from Indiana!

[freshcoastrider]

Im only 7 minutes in, and already I have learned so much, its amazing that this is free. Massively under rated for the view count. You have talent, keep on making these vids.

I just was recommended this channel came in looking for copper and i found pure gold

[ThinkFreely]

You've certainly earned my like. Don't tell my wife, but now i really want to swap and/or supercharge my 2023 Forester Wilderness. Lol

ROFL - "Don't be a barbarian!" and at 24:07 you are so delicately gently hacksawing the board connector. ROFL. Yes, using how air station and/or a vacuum pump with solder iron is so much slow and complicated (and requires hotair station and patience ) - hey, hacksaw works too :D + often there are premade boards that you can solder the OEM connector to and wire it non-barbarian way. I'd grab a spare ecu from junkyard and find a premade board for it - most cleanest, according to me.
Great video! I'm a Subarist too and that's why I found you. Keep up the great fun!

Sir. You are very good at teaching something that usually seems very complicated. 😮 Everything seems clear and understandable whenever you speak. Thank you.

[jamesa.buchertjr.]

By far, the most informative, accurate, and well put together videos I’ve seen on here! Not only do you cover the basics clearly, but you explain complexities understandably, without being dry or “preachy”. I’ve followed Smeedia for some time, but have always found myself somewhat annoyed by the end of his postings, if I can make it that far. I’ve been involved in the field for years, and have a soft spot for Subaru. You’re not only genuinely knowledgeable on what you present, and easy to follow, even with complicated materials such as wiring and CAN BUS integration, you’re actually very personable and have a great sense of humor. Some use humor to cover for their lack of knowledge, or underlying Tourette’s syndrome, or both. You manage to keep my interest and be entertaining as well. Not easy for most to do. Most of all, I love that you use what’s out there already, and do it cheaply for fun. That’s what it’s really all about. I look forward to your next posting. And enjoy that Outback! It’s inspired me for a future project, though I’ll probably go the cheaper route with a factory ECU. But I’ve finally seen a supercharger done well on a Subaru. I’d love to manage to do a setup with a new STi 6 speed, and a low profile blower, going for a true sleeper look, (No hood scoops).
Keep up the great work. Great production editing too btw! Thanks.

this video was well put together, succinct and straight to the point in a clear and concise manner. a saccharine *thankyou* for the huge amount of time that would've gone into making this.

As someone who's halfway through a v6 swap into my 5-speed forester, the wiring was admittedly, daunting. Now knowing a standalone has so much interoperability is extremely useful. thanks man.

I commented on this post 8 months ago and now that schools been out for about 1 1/2 I have an engine swapped aw11. The engine's swap from a jdm ae101 being the 4agze and boy I have to thank you. The car is still miles away from being close to finished but hearing the engine that didn't belong in the car start-up for the first time is a once in a lifetime experience. Shit sounds corny but honestly, it wouldn't have been possible without this video and the general encouragement you show towards taking on daunting tasks such as these. So this is a thank you for such a cornerstone in the automotive world.

I’m about to do my first (and possibly only) engine swap. Your translations of this demystified so much of what I’m studying before starting.

[samplesample]

This is super helpful, I was planning to replace my stock ECU to future proof my car! You rock and thanks a lot!

[imcrow]

thank you mr goatee man, youve taken my procrastinating down from 6 months to 3 months

[jr_inc]

I suddenly understand! instead of just guessing. I made a custom wire harness with fuel tech for a motorcycle build. This is the first im hearing of high and low side😅

[LokiCDK]

My family mechanic just swapped mine. I recently watched a thing on making your own ecu wiring harness, I'm glad I have a specialist who looks out for me, but it makes me want to do it myself when it isn't costing my ability to get to work.

[jdmking]

I’m in the process of doing a EG33 swap on my bugeye. This has been absolutely best video I’ve ever watched. Wish me luck with my swap!

Finally, The one that explains all has RETURNED 🎉

I was originally looking for a wiring schematic for a motorcycle engine when i found this masterpiece... Bro just made pasta for my brain to digest from all that spaghetti!!!! Clicked Like, subscribe and share!!! Bravo sir!!

[RandomlnternetGuy]

This channel genuinely makes me excited when you upload. Great fucking content dude

[darthmikey]

Thank you for taking the time to make this video. You just took what I thought was the biggest automotive mystery and made it a headunit installation.
