Help with HPTuner 2.0

Hi, I just started working with HPTuner and have, what I am sure of, is a really easy question.

How the heck do I get my cylinder airmass(g/cyl) on the chart display. Dont I need this info so I know where to remove timing?

Thanks

You don't necessarily need it in the chart display for timing (if you did, it would be there by default). It's already there in the Histogram display if you need it.

If you do want it (or anything else for that matter) open the Chart view and right click and choose Chart Settings. There are 5 charts that you can put it in. On one of the empty rows clcik on the X and then select the PID you want (ie: Engine/Airflow/Dynamic Cylinder Air (g/cyl). You can then put a description in the next cell, then minimum and maxinumu values (and lastly, color). Then click the REFRESH CHART button on the bottom of the dialog. Then close the Chart Settings dialog and you got it.

Why remove timing unless you have knocking going on. If you are scanning and getting knocking a particular RPM's, you can back off timing at that RPM-g/Cyl. If you are getting lots of knocking, what changed to cause it?

If you adjust timing in specific areas, use the Polynomial Smoothing to even it out all around.

Good luck...

Thanks a lot

The car is tuned and not getting any knock on the dyno but at the track I am getting 2 to 3 degress towards the end of 4th gear.

Thanks again
