I'm also searching proper settings for these injectors.
However here is a good info:
http://www.racetronix.com/product/Injectors/FI114961_Brochure.pdfMaybe wrong but current setup is the following:
Inj eff rampup 1200 (it seems too short according to the above datasheet + I got 100% duty cylce where it shouldn't been)
Inj open time 0
Inj Volt rampup 4080 (using TS diode)
Inj Voltage compensation 400 (no clue, but I think it should be lower)
