1. First thing you want to do is get a datalog of your car doing a WOT run in either 3rd or 4th gear.
2. Open up KManager and go to File>Open and pull up the Calibration that you were using when the datalog was taken.
3. Click on Datalog>Load and select the new datalog.
4. Go to Options>Settings>Lambda Overlay and select "Air Fuel Ratio". Under "Medium Load" change the value to the desired AF Ratio. The KManager comes with 13.5 but you can change this to 13.2 for best performance on NA cars.(See Following ScreenShot)
If you have FI, please input the desired AF value into the "High Load" field.
Best AF Values to Use:
Naturally Aspriated = 13.0 - 13.5
Forced Induction = 11.5 - 12.0
5. Once both the datalog and the calibration is open make sure you are viewing the Fuel Tables and not Igition. To do this press F5 to view the "Low Speed Fuel" Table and F6 to view the "High Speed Fuel" Table.
6. Click on View>Fuel Adjustment or SHIFT+F5. Also make sure "EDIT ALL TABLES" is checked. (The tables should look like the following)
7. Now take a look at Columns 8-10. It will bring up values either in positive numbers of negative numbers (Eample: 9 or -9).
8. These numbers indicate how much fuel needs to either added or take away on a particular CELL. These numbers are percentage (%) values.
9. Select the CELL you want the edit and press CONTROL+J.
Although you can adjust by each CELL I suggest the following.
*NOTE* If you want your fuel curves to stay linear to the other curves and not cross into each other then make changes to columns 8-10 instead of single cells.
Lets say column 8 @ 6000rpm says to take away -6 percent and column 9 @ 6000rpm says to take away -2 percent of fuel. What you want to do is highlight columns 8-10 and take away -4 percent which is half of both suggested values. ie. 6+2=8/2=4
10. This will bring up another window that reads "Adjust Selected Values". (See following)
11. There are three parts on this window and you want to use the first part that reads "Percentage Adjustment.
12. Input the percentage value into the "Percentage Adjustment" field. (Example)
Noob warning!!
If you open the "Adjust Selected Values" dialog, and then decide to not put a value in and hit OK instead of CANCEL, it loads a 0 in the value for all 6 cam angles, This will be a pain in the ass to recover from.

13. Do this for every CELL between columns 8-10. Dont forget to press F6 and switch to the High Speed Fuel Tables and make the changes.
14. If you want to view the actual Fuel Table numbers go to View>Normal. You can now see the actual fuel numbers for each cell.
This is how the window looks when you are looking at Actual Fuel Values:
This is how the window looks when you are in Fuel Adjustment mode:
15. Save the calibration and upload to your car. Do another datalog and do the same procedure. If you are doing everything correctly you should have your car with a perfect AF tune with 3-4 runs.
16. Please make sure that you are using correction values in the temperature compensation section of your calibration. To see the values go to Window>Paramenters>Compensation. Hondata recommends the following:
If you tune your car with the recommend correction values you should "almost" always have a perfect AF no matter the temperature. Remember all cars are different.

Conrad has created a great Temperature Calculator. If you do not want to use the Hondata values you can calculate your own correction factors. I included this because all cars work different and not everyones car is going to work well with the Hondata assigned correction values. Please read up on that thread to get more info on how to use the calculator.
ENJOY!
