15 SIGNS OF A BAD ECU (ENGINE CONTROL UNIT)
#enginecontrolunit
In this video i will tell the 15 symptoms of a bad ECU Engine control unit and explain them.
An ECU’s main job is to keep the engine working smoothly. On cars fitted with electronic fuel injection, an ECU can control the amount of fuel that enters the engine’s cylinders.
This optimises the fuel-air mix in the cylinder when it’s compressed, which in turn maximises the car’s power and reduces the amount of fuel wasted

This means in the actual sense that the functional principle is based on an oxygen comparison measurement. The probe compares the residual oxygen in the exhaust gas (which should be approx. 0.3 - 3 %) with the oxygen c...

Top 10 Most Expensive Cars In The World 2022
So you start the car and it won't idle under 1500?😊😊😊😊 This is what you're saying!
Is this a pre 2021 model or a later model? It would help to put the model and age in the description.
it's 2015 model
@@topuniversaltech1482 Thanks, for reference the 2021 model is basically the same, just different clips, and due to being in the same location a pain to get the filter in and out as it hits the floor, but it does go eventually.
Very good instructive video. I like the format.
Я куплю до конца года отправьте и читайте свои деньги
Привет как могу я заказать такую машину Узбекистана
Thank you, so ECU is the 'brains' of the car.
Short answer yes it is
Bad gas cap
if the gas cap is not sealing properly it can cause fuel vapors to escape and it leads to a decrease in fuel system pressure
Are you talking about when the car is moving or at iddle as my car is not reving past 3000 RPM and the speed is going to limp mode at 100mph. But at idle if i rev it the RPM goes past 3000 RPM to the end. What is the problem?😊
Well Many modern cars have a built-in rev limiter that prevents the engine from exceeding a certain RPM while in neutral or park to protect the engine. But it can occur even in idle in erlier cars, as for you car I would say that you should plug in the OBD 2 scanner to check for the cause of the problem, to be more precise
@@topuniversaltech1482i have checked through scan machine and no any code. But when am driving when it reaches 100mph doesnt exceed that speed, while maximum speed in my car is 180mph and i used to drive it to such speed before. What can be the problem now?
sloppy shaking worthless video is not acceptable,
Sorry next time I will do better
Is it worth buying in 2024?
Если не требовательный для играм, а где жизни то да стоит
How’s the battery on that thing by the way?
4500
Btw where did you find this?
Where did you find the SD 865+ variant btw?
Note 20 ultra or iphone 11 promax ? For gaming and photo
11 pro max it scores higher in benchmarks
The camera will be better on a note of 20 ultra 108 megapixels
Do you have the green line issue? I'm planning to buy note 20 ultra pls reply thankyou
Hello! I have almost a year since i bought my Note 20 ultra and i didn't have any issues
@@topuniversaltech1482did you software update?? And is it snapdragon variant?
@shanchar yes I did, ofc Snapdragon 865+ and still today works very well
Do you need a SIM to activate?
No you just setup the phone and you can use it
@@topuniversaltech1482 oh ok
@@topuniversaltech1482so easy right? No strings or hurdles?
Thanks very much l have learned something.
Glad it was helpful!
Very helpful information thanks brother
Thanks for the kind words SOHAIL🙏
Hi, my audi a4 b7 intermittently goes into limp mode only when slowly accelerating from a stop. Car doesn't go into limp mode at cruising speed. When light turns green i just lightly pressed on the gas pedal and it goes into limp mode. There are no check engine light or codes. Any help would be greatly appreciated. Thanks
Hello! Well Common causes may include: 1 Faulty sensors (such as the throttle position sensor or mass airflow sensor 2 Clogged fuel injectors or a failing fuel pump. 3 Ignition system problems (spark plugs, ignition coils). 4 Transmission issues, including low fluid levels or a malfunctioning transmission control module. Cant tell exacly what part to change without doing a proper diagnostic! Please consult a professional mechanic nearby to perform a thorough diagnostic to address this issue properly
Thank you
Thanks for this information.
Glad it was helpful!
What will a performance throttle body do, is it a big difference ?
Throttle bodies control how much air enters an engine. Performance ones boost power while keeping the right fuel/air ratio, so it has some difference
SD865+ or Exynos 990?
I bought THE SD865+ version
@@topuniversaltech1482where did you find the SD865+?
My car has rough idle probably it may be an injector...
Probably! I would suggest to look at the spark plugs too...
Thanks for this vlog 👍
how's the touch responsive?
Its good with the 120hz at 1080p still a nice phone
bro do you have iphone xs max? if you have what's the best for you note ultra or the ip xs max? help pls😭
Thanks for watching! Well I use a lot the multitasking, s-pen, and I like the screen too, + it has SD card 😂. Otherwise iPhone xs max still a solid phone, it depends on what you use it for.
It would have been nice if you kept the camera steady
Sorry about that! It was a busy day and I had a lot of tasks, it was kinda hard to work with one hand and filming with the other one, I will do better next time. Thanks for watching!
I have gas leak from the fuel rail , the car misfires I think it's this fuel pressure sensor
make sure where your leakage is, and if you're having leakage from this sensor then replace it
Фантастическая машина!!!! 🔥👍🙌
Is it worth it still in 2023
Hello there, I bought my Galaxy Note 20 ultra couple months ago, and it's still very capable phone , even in gaming it runs nice , I think it's worth it, you can find in cheap price now
