💬 How ECUs Work - Technically Speaking

In this video we go back to the basics and explain what exactly an ECU is and how it works.
It's one of the most requested topics so we hope it'll shed some light on the subject and help you understand some of the more tech-heavy videos on our channel. Enjoy!

What's interesting is how the driver fits into the equation. Just because fuel injection and ECUs are better doesn't mean they will always win a race. Chassis tuning, driver ability and weather all play a role in the over all tuning picture as well as individual knowledge of conditions and the race track itself.

It's fascinating to see how one single part of a race car can become an entire industry where companies like Haltech spend millions of dollars to push the envelop and further what's possible. Pretty cool. Great video that is easy to understand without being watered down.

Wow after so many questions about ECU it's the first time I actually heard about the basics.

[wonniewarrior]

I remember replacing my battary once. When I restarted the car, the dashboard flashed 'BASE'. It turned out the ECU and car other computers was reset to base figuires, and the instructions required about 200 km for the ECU to relearn the engine operating figuires for my style of driving and habit.

You guys really hit the market with the ease of install and functionality of your ECU's.
I have never wanted to tinker with engine management in all my life due to being afraid, now I can't wait to save up enough for an Elite 750 for my '92 vg30.

Outstanding. You know I was just watching with volume down because my daughter is trying to sleep but what I saw with you drawing was fantastic it would be cool to have you drawing everything I just seen in video lol I learned so much

[sardengineering]

This isn’t a new release but the information shared together with its delivery was spot on, why would you not want an electronic engine management system! It’s great when manufacturers take the time to relate to the wide consumer market. This shows a wealth of commitment matched only by a passion to achieve the best possible end user experience.

Thanks again Scott and thank you kindly to Haltech for their dedication!

Glad someone does videos, that don't assume you already know the basics.

[thvarebel]

Scott, thanks for the video...it really condensed the concept of how an ECU vs. a carb works. My only question is: if I'm not obsessed with performance (and not an electrical engineer), and I just want to keep my bike running steadily and reliably, where is a good place to start learning how to interpret engine trouble codes and how to diagnose electrical problems instead of having to go to the dealer every time I get a bad code? Having said that, am I better off sticking with my carbs and throttle cables :D ? Thanks and cheers!!

Dear Scott
Basics of ECU very well informed & executed, keep it up👍👍

[globalcomsur]

Very educational I''ve unstood everything you were talking about ., Thank you so much sir

[point]

Great explanation and breakdown, Scott. Still a lot of confusion out there about how ECUs and tunes do.

[lukestuart]

Thanks Scott. What was a really informative video

[jessepinkman]

It really helped me to understand the ecu system thank you 🙏

[saadnouri]

OMG !!! how much detailed science and technology humanity have reached !!! i can safely say : i know nothing nothing at all !!!!

[htetpyaekyaw-hendrik]

Thank Sir !!!
I have presentation to do tomorrow and this really helped me a lot !!

[braidensymonds]

I'm an auto electrician by trade and would like to learn more about fault-finding and repairing ECUs and modules in general. Can you please advise on an university or trade related courses to learn the in-depth information on how ECUs are constructed how to test their components and what components they consist of. I have A fair understanding from my own research and fault finding throughout my career but am wanting to take it to the next level. Please keep the content coming

[nelsonmagtanong]

Nice video very imformative meaning to say we need to do some adjustments on our ECU if we are considering of changing our exhaust system thanks for sharinh the knowledge.

[pjwoo]

Please forgive my ignorant question, but @ 4:58 and there abouts, you draw red wires going INTO the 'out' side of the ECU.
I would have expected that the 'out' side would show wires pointing OUTward, figuring that the signals have been corrected, and the 'revised' signalling is then being sent OUT (to the various sensors I guess) to make the necessary adjustments for efficiency.
If that's not how it works, well then I guess I sure missed something.
I really enjoyed your presentation.

[moroccokhattak]

Great explanation I was crazy about how ecu works, then this give me the idea. Thanks guys

[jaybiekurishima]

Thank you. I understand the visual of ECU car programming.
