Help GamePad Mapping on RemixOS 2.0


I bought a Gamepad for my Tablet looks and feels great, but it has very bad drivers and programming.
This one

I tried to change the mapping with some Apps (GamePad Tester, Game Controller Assignment Interface) and the keylaout files with root in /system/usr/keylayout/.

Some buttons are reversed so tried to change it in /system/usr/keylayout/Vendor_0e6f_Product_0201.kl the keymap of the Gamepad but nothing changed. When i change it in the Generic.kl it works.

This is are screenshot of Gamepad Tester with some changed working Buttons.

All Button now mapped correct, but only L2 and R2 are not mapped correct. They are triggers and together they build the AXIS_RZ.

L2 has the range pressed -1.0 to released 0.0 and R2 pressed 1.0 to released 0.0

So is there a way to Split the Axis and remap it to AXIS_LTRIGGER and AXIS_RTRIGGER. or there are anywhere better apps to Remap it

Here are my Files


Sorry for my bad english iam German.
