Mine has always had a little timing glitch since new. It will randomly misfire one cylinder (?) and the tach will 'spike' down, like you shutoff the car for a split second. There's a corresponding spike in the RPM datalog too. Not sure if it's internal with the box or cause of my wiring fiasco causing some sort of feedback of built up chargezzzz. The misfire was bad with the 1.6 coils/external ignitor, got a lot better with the 1.8 coils, and is very rare with the toyota COPs, but the tach drop is still common. Happens a few times to/from work. Sorta annoying.
