I stumbled on this chart of pulse widths courtesy of Brad Anders...Hopefully it is a starting point for anyone tuning an aftermarket FI ECU who also use stock injectors and fuel pressure.
0.1ms resolution is necessary. The charts give data for PW based on manifold vacuum and RPM. Stock 914 FI pulse widths |

Interesting bits of trivia here: the shortest pulsewidth is 2.3ms, which is longer than I've seen some settings shown here, even for smaller injectors. The longest duty cycle is 73%, which is well under the usual 80% ceiling noted for most injectors.
