The fuel injected version was standard fitment to the second generation Honda Today (JA4/JA5), which was only available as a passenger car version. The previous generation Today remained on sale and offered a fuel injected engine in some models (XTi, QXi).

E07A (MTREC)

In order to extract higher power from a naturally aspirated engine, Honda modified the E07A with a MTREC (Multi Throttle Responsive Engine Control) system, placing individual throttle-bodies on each of the three cylinders. The system modified the air-fuel ratio of individual cylinders based on rpm to give sharper throttle response while also maintaining a stable idle. When fitted to the Today, the engine was tuned for somewhat less peak power in favor of more low-down torque. *SOHC 12 valve MTREC *Displacement: 656 cc *Bore & stroke: 66.0 mm × 64.0 mm *Power: / 7,300 rpm (Today) / 8,100 rpm (Beat) *Torque: / 6,200 rpm (Today) / 7,000 rpm (Beat) *Applications: **PP1
