ID1050x injectors

Wondering if anyone has the proper injector data for injector dynamics 1050x injectors (p/n 1050.48.14.14). These are in a 2012 civic SI k2.4 n/a, rbc swapped, skunk 2 intake, 3 inch megapower rr exhaust. I have the data from injector dynamics but it doesn't seem to be correct. I have fuel econ alternator and eld disabled so voltage is normally 14.2 volts. I have read that ID's data isn't the most accurate when it comes to flashpro. The fuel system is stock other than fuel rail and injectors and e85 sensor. Problem is that when set to injector data from ID the fuel trims are all over the place in the lower loads. Just wondering if anyone has the data for these that have worked. I currently switched over to an afm tune and have been scaling the afm for it to run properly but I am still getting weird trims in the lower loads, once I get afm mapped I plan on going back to a map tune and fine tuning it there. It seems to like the afm more for idle and low load and rpm but runs better at high loads on map sensor.

Ok so what I actually ended up doing on my drive home last night from work (it's a 2 hour drive) was loading up the 1000cc tune for my car, I then input different data into the injector size until trims were fairly low at 3000 to 4000 rpm at 50 to 70 kpa without adjusting any tables. I then changed the injector opening time to where the trims were in sync with the trims from the previous tests at light throttle deceleration over a long period of time. After jumping back and forth doing this I ended up with a current injector size of 1175 and opening times of 8.2=2056 10.2=1500 12.2=1180 14.2=974 and 16.2=840. The only modifications I made to the out of box tune was subtracting .3 afr from lambda tables and wot tables to compensate for ethanol content in gas and switching off the misc parameters necessary for me. Using only the unaltered afm curve I was able to achieve +5 % trim at the load and -8 % on light throttle deceleration. There are some areas of the maf curve where I saw a trim of +13% but I am assuming that that can be taken care of with fine tuning the afm. The car idles much smoother and sounds healthier overall and afr is a lot more consistent and stable. Once I get the afm curve dialed in i plan on switch to map tables and making proper adjustments. Does this test and results seem sufficient or do you think I should get the trims in closer without altering the afm curve? Keep in mind voltage is locked at about 14.2 volts so that is really the only opening time I have been able to verify.
