FES readings Graph Any help?

[robthorpe123]

Hi im new to the forum so sorry if im posting in the wrong area

my car is an Alfa GTV 2.0 twin spark 1999 PH 2

I have a screenshot showing a few parameters including the Lambda reading which seems very erratic to me with the norm being 1.000 mine seems to show readings of 1.109 as a high and low points of 0.863

Im just trying to improve the MPG really it seems abit low at the moment probably only 20-25mpg at all times out of a 2.0 twin spark seems a little low

the air intake seems to follow a pattern with the throttle position so im not sure if that is correct or not

Any Help would be great thanks

Hello

There are no fixed values ​​for the parameters
it is only important if they are logical.

Therefore, it is first of all important
do you have an error?
or an abnormal behavior of the vehicle?

Otherwise you these values ​​serve very little purpose.

Hi

sorry for the late reply

Well the car does seem to drop the revs too low when setting off, hunts a little bit, however the idle itself is solid

Is there a way i can upload the test log to you on here? i just made one and again it seems erratic behavior to me just interested to have another opinion

Thanks
