HRTunerProxy - Zgemma H2.S running Latest Wooshbuild

Anyone know if this plugin still works?
I am unable to find it in the list of downloadable plugins.

I have tried to install it manually through FTP, but i am not 100% sure how to do this?
Obviously if the plugin no longer works this would be pointless anyway.

Many thanks ! :)
