There's a cost attached to the bolded part.
While idle, the LTFT was the same in both scenarios, please check it again.

Besides, the essence of motion is to have varying RPM which I already did. Watch the video again or contact me on whatsapp if you want me to send it to you.

whatever I know today the credit goes to my oga and I can't stand your boys to be rubbishing him .

Will comment after going through factory information...no time now

cc: oyefelix

MODIFIED:

1. The fuel trims both STFT and LTFT provided that they fall between 0 +/- 20% are said to be normal according to factory specifications. ECU will only set lean or rich codes if vehicle out of factory specifications range, but values in experiment by Gaz.zuzz within factory specifications, so there can be no lead code as speculated in this case.

2. Will address other part(s) of your query later, when I cross-check the other values with the documentation.

honmusa:

you have introduced a undesirable variable into the test by reving the car ,we need to take all reading from same condition of idle .This test is not valid .

What a thread!

This is Cartalk, known for maturity and mutual respect. It's is supposed for knwledgeable minds and learners alike. We don't need to hurl disparaging remarks at each other. Somebody does not know what you know simply because he has not been exposed to it. A perfect mind is all of us put together. I love civility but know I have been found wanting too! Too much space and time have been taken here on personal attacks, instead of education.

Peace everyone!

On to the matter.....

Even if the air filter hose in a MAP system is burst completely open, and funnel attached, the MAP reading will not change, and the engine should not run lean. However, if there is a post MAP leak, there will be engine performance issues.

Even in MAF design, a post MAF leak will have little effect on the MAF reading (depending on the size of the leakage) but will cause performance issues due to the unmeasured air.

The difference in STFT and LTFT is in their names. Short term tells you what is happening now while long term tells you what has been happening. Assuming the open hose has an effect on the FT in Gazzuzz experiment, it would show in STFT, not LTFT. If a lean or performance code is not set in 100km, I don't see it setting. To eliminate all doubt, run the car in check mode.

On the flip, for that engine to have a LTFT of 16% means there is an underlying problem. There is too much air going in, or there is fuel supply problem. I personally will be concerned if my LTFT is more than 3%.

Shalom.

Did you watch the video or read all the values in my post at all?
I don't understand what you are or pretending to be by shifting goal post anyhow.

camry 1998 5s-fe engine.

Vehicle has no check MILs stored on Engine ecu car is carefully used and maintained by Gazzuz

Now I dont have time or data to waste making a youtube video, so I will share live data readings.


Aim of this experiment is to show that MAP values will NOT change with or without the air hose installed on ANY vehicle that uses only the MAP system.

Also fuel trim levels will not show a significant change if air hose is disconnected from throttle body.

Car will not enter into lean mode I left like that perpetually.

hahahahahaha I now see Clearly Sha. it is well. at least u have learnt something from this thread and that thing is..... a barking dog should be sure it's teeth are in good shape to bite or else.... yawa go dey!!

also don't go throwing tantrums anyhow just cos u have them in excess.

be grateful for what u have learnt from this thread.

make I go suck my feeding bottle before daddy go beat me oh
I'm also a demeanor

r u?

LeJeun3:





I am

chukel:
honmusa, we are still waiting for your experiment and unadulterated result.

obekediamondfuto:


the simple question is....... R U A DEMEANOR?

chukel:
pls in what context is this demeanor being applied sir.

honmusa:

no sir ,fuel trim greater than 10 is sign of lean mixture for that model and thus already an issue ,fuel trim up to 25% will trigger P0171 which like point of saturation .wen I come out with my test later I will show you the proof

honmusa:

never mind I will do this test soon and you will see what I mean .
