Hi, I was tuning my S2K yesterday(with the Aem Tuner 3.2)which i have an Aem Ems Series 2 on it and when i tried to do quick trim on my fuel map(O2 FB On)it just made the values in the cell 0.0 ending up spiking my fuel map. I've checked the parameters again and everything seems ok, does anyone else has this problem?

 

This will happen if you've selected the "AEMPro style" method for applying percentage changes to the fuel map. It's a bit of a quirk of how the software works.

To fix it, you'll have to do a few things. First, go to AEMTuner's Preferences (Ctrl + P), Applications, and under Registry Settings hit "Click to Reset". Now, go to your fuel map, select any cell or cells, right-click and choose "Percentage Change", type in 0 for the value (this way we won't alter the fuel map), but this time, choose "Default" style instead of "AEMPro" style, and check "Remember my choice". This method means that typing in a value of "5" for a percentage change will ADD 5% to the selected cells, and typing in "-5" will pull 5% from the cells. The AEMpro style would instead be "105" and "95" to make these changes, respectively.

The Quick Trim feature should now work. You can configure it in the same Preferences tab and even change the hotkey under the Hotkeys tab.

 

Thank you very much i will try it and i will see if it works, it still seems like a bug to me though cause i was very familiar with the aem pro style how could they ask you to % add/pull in aem pro style with creating such issues? Anyway thanks for your help
