Assalamu alykom: I see for the rpm that that 266hz needed for 8000rpm, in fact 266hz is almost 16000 pulses per minute which is the double of the rpm.. so the sensor in the car is sensing the double of cranckshaft rpm? Or may be is sensing (sending pluse) every half revolution? I am not sure, I have to investigate the cranckshaft sensor.
Wa alaikum salaam brother I don't have any idea about car circuit. So I cannot comment about signal processing in car Might be ECU will send divided signal with some specific ratio
@@HaseebElectronics Ok, I found it 😁, In the flywheel there are two missed teeth, one to detect where the piston is at the very high position, the other for the low position of the piston.. So the magnetic sensor called engine speed sensor or top dead center sensor will send two pulses every revolution of the cranckshaft. So the rpm will be : freq(hz)x60/2. For your example: 266x60/2=7989rpm almost 8000 Note that the number 2 (missed teeth) may vary for orher cars.
i think the other display should be the related with the tire radius and speed with the same understanding (also used at the abs brake system) the rotation of the wheel may send the AC signal (as the frequency) to the ecu.
Thank you for another great video. Please can you confirm (or perhaps make a drawing to demonstrate) the type of signal injected e.g., square wave, sine wave. Also, what was the peak voltage? Thanks.

@@progsam wonderfully awesome
I am thankful for your valuable information
Please accept my beat regards

وعليكم السلام ورحمه الله وبركاته ❤
Thank you very much sir! ❤
Your appreciation is highly valued. 🙏

it is square wave. normally 5 volt to 10V peak signal is good. as it is injected to a voltage divider network before reaching to microprocessor
@@HaseebElectronics Many thanks for the prompt reply and for the information.
👍👍👌👌
👍
what is the model no: of that frequency generating unit..?
it is XY PWM generator
you can watch video number 820 for more details
@@HaseebElectronics thanks lot bro.. i found it....th-cam.com/video/IxBhTzklJLw/w-d-xo.html
Sir your vehicle is going very fast dont go above 80 kmph. 😂
@@rajkhumar001 but I can't drive car on road.

most welcome
