Cheap chinese aliexpress Map sensor response time

Hello, I've got a question about a new MAP sensor I've ordered and installed on a car from Aliexpress site. It was like 10$... This is the link m.aliexpress.com/item/32636654491.html?s...tem.3.14e3f19cyIRJpJ


So , I've noticed that, to my opinion, this sensor has greater response time than it should. It is stated that MAP sensors should read pressure at about 1ms.
To me it seems that this sensor has greater delay before measuring pressure than it should.

Here is the csv table which I recorded on one longer trip during many climbs and downhill driving... Car wasn't able to maintain speed greater than 40 mph on uphill driving in 4th and even 3rd gear manual transmission, 105HP car, Chevrolet Lacetti 1.6 litre engine).

From looking at csv to me it looks like some bogus reading from MAP sensor, like it was delayed.

Please look at trip details in csv and please tell me what you think about it.

Also pdf for maybe better viewing on link below

Since you cant see all text in first row for column descriptions, starting from second column you have "Absolute throttle position"; "Engine RPM", "Intake manifold absolute pressure"; "Calculated load value"; "Ignition timing"; "Fuel system status"; "Vehicle speed"; "Short term fuel trim".

Here are screenshots to multiple transitions of load to intake pressure parameters if thats of more help to analyze of what is going on with map sensor.

No worries.

I'm also gonna move this one to the Diagnostic Tools section.

Here above is the link for same csv in pdf format for the trip log mentioned in the first post.

Does this behaviour seem ok to you?
This was taken on a short trip while car exhibited a few hickups (drops in rpm) which it does sometimes when it's cold on first start and run...

maybe this is better more clear picture
