Franco's Kernel on the N4

Hey guys I've just flashed franco's kernel on my nexus 4 and I'd like to know how the bloody crap I can change the vibrate amp without paying for the franco's kernel updater app? is there a free app that can change that?
P.S. I don't want franco's app cause I don't have money on my card now so that's the problem.However feel free to give me some advices on what should I do with this brand new kernel on my phone :)
