The other main issue with this type of "conversion" is that it does not alter the injector dead time, starting and advance tables in the ECU. These will contribute to harder starting that gets worse at lower temperatures. I know of vehicles that run on E85 and methanol that start fine at very low temperatures, but they have had the ECU correctly tuned to achieve this.
Swapping injectors is at best, a crude hack that has the potential for lowered efficiency and engine damage.
