That's precisely the problem. Thank you so much! I was certain it was user error, haha.

Sorry, this is a USDM FA5/09 Civic Si

Howdy all,

I am struggling with something that might be a bug, or might be user error. When I go to adjust any value in the fuel or timing tables, any of the keyboard shortcuts to adjust values (CTRL+I/CTRL+D) or the right-click "adjust value" dialog adjust that MAP/RPM value across all cam angles ...

Are you uploading to the ECU after making changes?


I am certain I do. My workflow is:
* make changes to the calibration
* save it to a unique file so I can track changes
* upload it to the Hondata Flashpro module
* disconnect it from my PC
* hook up the flashpro to the ODBII port and follow ...

I can assure you that this does work and many many people have tuned using this and have not had any issues. You need to try with the stock intake.


And I totally believe that it must work, because it's there and in the documentation. But what I am lost about is when I change the table values ...

The problem may be with the intake and how the air flows through it. If you put the stock intake back on, does it work as it should?


I haven't yet, mostly because of how much of a pain it is.

What I don't understand is how I can't tune around this? Again, if you compare the sensors, you can ...

One more thing--here's an example of the AFM flow table making zero difference. I made huge changes to the AFM flow table between v1 and v6 and at idle, there's no tangible difference in the voltage-to-flow rate and it should be *way* less.

I do have the "rev hang eliminate" option set--does this ...

Have you read the info in the help file: https://www.hondata.com/help/flashpro/tuning_afm_flow.htm


I have and I've been following those instructions. My SFTF are between -8% and -15% from 1.1V to 3.2V, and twice I've reduced the flow rate on the AFM table by 15% and seen no change in the g/s ...

Sorry for the stupidly long title, but this more or less summarizes the struggle I've been having.

Long story short: got a new HPS Cold Air Intake. I know from past experience the airflow differs greatly thank stock, and if I let the car idle for more than 20 minutes without moving, it throws a ...
