Any difference in an injector's opening and closing time is far far smaller than an an ECU's ability to adjust fuel trim based on O2 sensor feedback. For example going from an EV1 to an EV6 injector the opening time is 0.3 milliseconds shorter. Good luck finding an ECU that can't handle that change. The whole "spray event happening a little early or late" is just not true.
The only thing you really have to worry about is having a similar flow rate and matching the injector's resistance. all 12ohm+ injectors are interchangeable. I've swapped 3 cars so far from EV1 to EV6 injectors and converted 2 cars from mechanical injection to EFI using EV6 injectors. All improved fuel economy and passed emissions.
