I'm only getting one line of data across the top

Probably something simple I'm missing here. I'm trying to log spark on rpm vs aircharge. I can get the full table to work with rpm vs map but that doesn't help me as much.
Here's a screenshot

Need to add Aircharge to your channels....everything you want to log, with the exce[tion of actual math parameters requires the parameter to be included in the channels table. Even with Math Parameters, you need to include the parameters that are use in the math expression.

Also as a note, if the Channel parameters are greyed out when connected to vehicle (or using Offline Vehicle Profiles), that specific arameter is not supported by your PCM/OS. Delete them to make more room for supported ones.

Thanks Ed!

Hi Ed, stupid question. Where do I find that aircharge table-I just dont seem to see it?

[mowton]

Dodge calls it aircharge and GM calls it Cylinder Airmass. There are two places you can find them and a third if you want to make one

All PCM's will have a parameter called Cylinder Airmass...just go to Channel and open the selector. HP Tuners also provides calculated cylinder airmass in Tools>Math Parameters>Maths -Predefined>Cylinder Airmass....remember these are made from the MAF which is not always accurate during transient pedal conditions. The third is to make you own which is what I do.

Start by logging Dynamic Airflow..you all know my definition of this...its the PCM's final airflow answer :-) The copy the predefined equation that uses the MAF ---- [50040.71] / ([50070.56] / 60 * 4) and replace the MAF Airflow with Dynamic Airflow -- ([2320.71]*(120/8))/[50070.56] and save it as Dynamic Cylinder Airmass or DCA. Now you will always know what the PCM using and will lnow exactly where in the spark table you are.....

I have the same issue with the graphs when trying to use cylinder airmass.

I had no such problems with the same vehicle using the previous version of the Scanner.

How do you enable the "Math parameter" (double-click ??)

Any help would be appreciated....
