Spark tables aren't the same with Histo tables.

[MadMarx]

Hi,

today I found out that I have some differences with the tables I set in Editor and the histogram table I get after a ride:

Spark table:


Histo table:


So there are difference up to 5-9 degree.
How can this happen?
Where could a spark advance adder be hidden?
I've set the AFR correction to ZERO and all others I don't know.

Looks like you made a custom histogram to me and set it up incorrectly.

[MadMarx]

I took the given histogram patterns as basis but the problem was that got only one line in the table with numbers.
The y-axis was empty.
So I changed the y-axis to "Mass Air flow" sensor to fill the vertical axis.
I also tried "cylinder airmass" but didn't get a result.

So what to do? How these higher advance values can come from?

[MadMarx]

And something interesting.
I changed at the AFR spark correction table the values to negative like -5 degree.
The result was, as soon the PE table got into action at full throttle the advance changed to 60 degree and power was gone.
How does this come from that a negative value suddenly rises the advance to 60 degree?

You change it back and fix whatever the issue was with your original setup.

Can you tell me how to fix anything?
The software is in use as it came.
The connector seems to work fine too.

If I load the standard histograms I don't get anything usable.
Have a look...the same table with the standard spark table that came with the software.

are you logging Cylinder Airmass in Main Table?

^^ The reason he's asking is because the histogram is just a plotter, plotting the given parameters and since you're only populating it horizontally, it's our guess that you only have the horizontal value in the table. Anything you want to show up in the histogram must be logged in the main table. Go to the main table, right click>insert>Airflow>cylinder airflow

look at his cyl airmass axis...no decimals. Thats the issue.

Mad marx post the scanner log please.

Yup, I opened up his cfg and cyl airmass prescision is at 0 not 0.000
