By the way, is there a chart to show what model car use what device? O a quick identification method?
Thanks
Great explanation .
Congratulations and thanks.
Couldn't be better.
Man amazing thank you.
ОтветитьAn forced induction engine doesn’t ‘need’ both a MAF and MAP sensor. This is simply for emission controls on OEM applications. The only critical sensors to make a fuel injected engine run are: Crank, Cam (only if SIDI), MAP, IAT and coolant temp.
ОтветитьWell done
ОтветитьGood knowledge in simple words definately clear doubt about Maf and Map sensors
Thank you Sir,
Isn't this the same as a PID detector?
ОтветитьI thought you wouldn't mention diesel engines at all, but you did... 🙂
So if I understood correctly, it’s less common in diesel engines, but nowadays they do have them, MAP and MAF? For example, my 2.2 i-CTDI Civic probably has one? If that’s the case, since the car is from 2008, I may benefit from cleaning MAF and MAP sensors or just replacing them and getting my fuel consumption lowered. It’s mostly driven in city traffic so the fuel consumption is around 8L/100km, that’s slightly aggressive driving.
Of course, amazing video as always.
Cheers
Great video. Very thorough explanation of a very complicated topic. Chapeaux
ОтветитьIt is very conducive to bring this up specially for a correct combustion into smoothie blast
ОтветитьNow I understand why the video is almost 20 minutes. lol 😂
Ответитьi thought map was just someone pronouncing maf badly
guess i learned at least one thing
I still don't understand why my car's engine has only a MAP inside the airbox, before the throttle bodies (ITBs). What is it doing in this setup?
ОтветитьI love booey
Ответитьsuper!
ОтветитьKarman Vortex Airflow Meters are still used in new non-turbo petrol Peugeots. With regards to older engines, I've most commonly seen them in Peugeot's 1.6HDi and 1.5 diesel motors.
ОтветитьAlways been a bigger fan of a MAP sensor
ОтветитьWow! ALOT different than the "ole" carburetors when I was in auto shop as a teenager. Very interesting! Thank u! Love "air" written on your hand, a great teaching tool. 😂👍🇺🇸
ОтветитьThanks for the great video! I have a question though: I saw some MAF sensors output a frequency rather than a voltage or a current. How do they work? I thought only Karman Vortex sensors output a frequency. I'm just getting into tuning, and please pardon my ignorance.
ОтветитьWHY ISN'T IT WEIRD OR NOT SUPRISING AT ALL THAT HE IS A BIMMER!
Ответить👍
ОтветитьLol he said the basics
Ответитьyour videos are absolutely beautiful..
ОтветитьGreat Video thanks
ОтветитьThree in the vane sensor, one in the ... I dunno. Something something low-key innuendo. I saw that.
ОтветитьYou're a brilliant teacher, well done ♡♡♡♡
ОтветитьTHANKS FOR THE VIDEO, CAN WE CLEAN THE MAP SENSOR WITH A CONTACT CLEANER?
ОтветитьThank you for this very useful info. But I still don't get how a MAP can work without a temp sensor? The number of molecules will change in an intake, if the pressure is constant but the temp change? So the temp must be known to calculate the fuel needed?
ОтветитьReally appreciate the quality and thoroughness of this video!
Thank you!
Great explanation. Cars ran speed density for a few years around 1990 relying on a simpler MAP sensor. I converted my own car to run a Custom Operating System speed density tune (with twin spark tables) and used it as a daily driver. It never missed a beat during the 10 years I owned it. (MAF sensor removed and P0102 turned off). It gave better throttle response and gained 15 rwhp on a back to back dyno test.
ОтветитьA little clarification on MAF sensors. They have two thermal sensors, one on the heater, another aside. Electronic control aims at maintaning a constant temperature difference between the heated and unheated temp sensor. Flow rate is evaluated based on the selected temp difference and consumed power by the heater. The use of two temp sensors eliminates the inaccuracy related to air temperature variation. In steady flow this sensor works quite well, but under rapidly changing flow rate may have dynamic errors.
ОтветитьIt surprises me that almost all the new aftermarket ecu's us Map instead of Mas because the Map doesn't react as well to engine upgrades. I guess that's why they let you input your changes into the ecu via a laptop.
ОтветитьI'm just gonna sit here and enjoy your beard
ОтветитьThis is great info! I always had always incorrectly thought "mass" stood for "massive"...lol
Ответитьcan an old 5 pin vane type be replaced by a modern hot wire model ?
ОтветитьThanks for expanding on the working of the Vane Air Flow Meter. My '93 Protege has exactly this. I just changed the air filter and the car bucks when I give it gas. Looks like either the vane is dirty - sticking closed - or the meter isn't installed perfectly horizontal. QUESTION: If the vane is sticking, will MAF Sensor cleaner fix it?
ОтветитьI know I’m a year late, but o got a ae86 afm sensor and have a ae92. Would it just bolt on and work no issues?
ОтветитьYou just cleared my 2 year confusion ❤❤❤ thanks a lot
ОтветитьGreat again man! Got a question about throttle body that no one ever answered but I believe you can.
I’m driving my car 80-90-100 mpg and I get off accelerator. The throttle body is now closed. Where does the engine takes the air to still run at 3-4 k RPM.
Same with the second gear why does it sometimes push me forward with my foot off the pedal.
Is the throttle body somehow adaptive and its not listening to your foot but to your RPM or what :))
I wouldn’t mind to see a video about this topic.
Wow man, thanks!
ОтветитьAre you Canadian bro? You have a very nice voice for lectures.
ОтветитьDoes Pipe Diameter affect a MAF reading?
ОтветитьLife is too short to drive Japanese cars.
ОтветитьIs the Afm that same as the throttle body?
Ответитьamazing🚩🚩🚩🚩
ОтветитьVery well 🤗🤗🤗
