i cant get these things to go below 1.6ms no matter what i change. Shouldnt the pcm try to pull them lower even if they wont actually work lower? This is killing my mileage. I am olsd cos5. a/f at 11-13 is killing my mileage. oF course with ANY load the a/f goes to 14.7 in autove mode. Any idea why i cant get the pcm to ask for lower than 1.6ms? I got every injector related table i can find cut up to 75% and it makes NO difference.
You might want to try searching for post from NitroRocket. He was able to get some 90+# injectors to work. IIRC, one of his tricks was to low the base fuel pressure.

thanks!! I know the voltage and ifr helps but didnt know about the "-" small pulse trick
eureka!! ill post more later but those things work!!!!
off the top of my heads I set
small pulse adjust to -3.9
injector flow rate at 13hg and higher (my eboost reads vacuum in hg i think) to 100 (efilive max)
and my fuel pressure was already at 43psi hose off.
This gets my inj ms down to 1.4...idle is 14.7 and decel is 13.0 ish.....i think i can get it better but that was just the rough start.
It improved my mileage tremendously and am now starting to see light at the end of the tunnel.
glad it's working out for you.
