460cc 2nd gen rx-7 injector constants

Just curious as to what constants you guys out there are running on the low impedence '86-'87 460cc 2nd gen mazda rx-7 injectors.
Sorta apples and oranges, but I'm running a ported 12A with just 2 of the Maza 680 low Z injectors. They test at 750ml/min so I'm pleasantly surprised. I run them with 5 ohm Ohmite resistors so as to not fool with PWM, etc. I use a .8 ms opening time and have disabled PWM via 25.5ms threshhold. This system works great and the resistors do not get even perceptably warm even after 4+ hours at 80mph cruise/]4100 rpm. 167 RWHP so something's working OK!
