I too have an E38 ecm and I recently purchased some 80lb FIC injectors from fuelinjectorconnection.com and requested all of the injector data from them so I can tweak my injector settings and scale the tune and they sent me the attached spreadsheet. Hopefully this might help you? They sent the spreadsheet with un-scaled specs/data and also scaled data (for the 63.5lb limit in 2007-2008 E38 IFR table). But they scaled it to 62.72% and I really would prefer it to be scaled 50% for ease of math in other tables so I modified it and need someone to check my work and see if I'm on the right track. So the first spreadsheet is what they sent me and the 2nd is the one I modified to get to a 50% scale. Thoughts?
