Yesterday was my first test day in the car with my new Geartronics paddle-shift system. I am blown away. It is like having a new car. The system, works perfectly out of box. It took about 3-4 days of leisurely work to setup, not rocket science, but just going slowly and carefully. I was concerned with the mix of components - mechanical, air system, electrical, closed loop sensors and software, but everything worked together perfectly. Both upshifts and downshifts are crisp and effortless. And there will never be another misshift or over-rev, ever. Computer does not make mistakes. So in a sense it helps protect both engine and gearbox. Kind of like engine/gearbox insurance. Well, that's what I tell my wife...
It really is a game changer as it allows you to totally focus on your driving. I dropped a couple seconds off my lap time right away, like in second session. It just makes it like a totally new car, really unleashes it, lots of fun. I would highly recommend this system to anyone wanting to make a fun, performance upgrade to their car. It really works. I am very impressed.
