I would like to know how to use the self tunning features in AEMtuner. I know I should be able to PC log and then have it self tune to improve the over all maps?

O2 F/B Tab:
Check that your O2 FB Target values are sane.

Options - O2 Feedback:
Set O2 Feedback control ON
Make sure the other options are reasonable. For auto tuning, I would keep your O2 FB rich/lean limits no more than 5%.

Tools -> Preferences -> Quick Tune
Make sure the appropriate channel is selected and set gain to 0.1. With a rich/lean limit of 5%, this means the largest adjustment made at once will be half a percent.

Tools -> Preferences -> Hotkeys
Set the hotkey for "Fuel Map -> Quick Trim" to space

Download and install AutoHotKey: http://www.autohotkey.net/~Lexikos/AutoHotkey_L/AutoHotkey_L_Install.exe

Save the following as "tune.ahk":

#NoEnv
SendMode Input
SetWorkingDir %A_ScriptDir%

Time:=1000
F6::Pause
F11::Time-=500
F12::Time+=500
F5::
Loop
{
Sleep, Time
Send {space} 
TrayTip,Autotune Update Rate,%Time% mSec,1,1
if(Time <= 500)
  {
  Time:=500
  }
if(Time >= 3000)
  {
  Time:=3000
  }
}

Right-click on tune.ahk and select "Run Script".

Now go driving and select your fuel map in aemtuner. Press "F5" when you're ready and AutoHotKey will press space every second. You can speed it up with F11 and slow it down with F12. F6 to pause.

Resurrecting an old thread to update it with new information and a script with different hotkeys.

So AEMTuner 3.2 to turn on Follow ECU - On the Fuel Table there is an down pointing arrow in the top right hand corner that will open the display settings but on this bar is the Follow ECU option. It took me a long time to find this information for some reason.

Next the Windows 10 and AutoHotKey and AEMTuner:
To run AEMTuner I have to run as Administrator, thus AHK can't pass keystrokes because it doesn't have authority SO run AHK as Administrator also and it can then pass the keystrokes.

Finally because I had to diagnose why it wasn't working I played with the hot keys and here is what I'm using:
set the QuickTune to F12
Start the script to Shift+F12
Subtract Time Shift+F10
Add Time Shift+F11
Pause/Unpause Script Spacebar.

Car OFF
I run the script first (Right Click on Script File - Run as Administrator).
Switch to AEMTuner, Fuel Map Tab, Make sure Follow ECU is on.
Press Shift+F12 to launch the key pressing.
Press Space Bar to pause the key pressing.
Start the car let it warm up
Start Driving
1) Press Space Bar when you want to start Quick Tuning
2) Press Space Bar to pause Quick Tuning
Repete 1 & 2 as needed.

NOTE as you can see I didn't change the script very much.

#NoEnv
SendMode Input
SetWorkingDir %A_ScriptDir%

Time:=1000
Space:ause
+F10::Time-=500
+F11::Time+=500
+F12::
Loop
{
Sleep, Time
Send {F12}
TrayTip,Autotune Update Rate,%Time% mSec,1,1
if(Time <= 500)
{
Time:=500
}
if(Time >= 3000)
{
Time:=3000
}
}

Enjoy!
