It was nice having to only unplug the ABS fuse on my Gen4 for trackday use. I've read the bike goes into limp mode if you don't use the dongle.My peeves with the ZX:
1) You cant turn the ABS off without an extra race part (dongle), and then its always off. WTF? BMW lets me on/off at will.
2) I cant turn the traction Control off unless I'm stopped. BMW I can do it on a full boil. WTF?
I also had the option on my Gen4 to turn TC off while off throttle and rolling via Woolich flash. Really disappointed that is not yet an option with the Gen5 flash.
