Toliski Posted September 25, 2018 Report Share Posted September 25, 2018 Hello guys, I just see an advertisement with KnockLink G4 ( something like a shift light but for Knock ) Is that so gorgeous as advertising says? Self calibration so you must no worry about gains, frequency, high RPM noise, fake knocks and stuff like that. Is that really so good?
