HPT:VCM Scanner: Graph: Logging wideband AFR error %
Hi All
I m looking for some assistance with getting my scanner to log AFR Error % using my wideband.
I have had a go and tried many variants and the output is always seems to be the same so i must be missing something in my setup.
I have attached the following
1 . Screen view of the PIDs that I m logging in the scanner relevant to fuel actual and commanded.
2. I have looked at the predefined maths parameter for AFR error to assist in determining the formulae i should use in user defined maths,
3. I have attached my user defined parameter and formulae
4. I have attached my graph setup for AFR error that looks at my user defined AFR error parameter.
5. Scanner graph output: when I run the log the blue square moves around like its plotting the values but there are no values ☹ coming up. Its like its there but I cant see it.
I have my wide band setup through my MPVI Pro analog 1 and is reading the AFR/Lambda
Appreciate your thoughts on what I might be missing in my setup.
thanks in advance
