Just spent 6 hours working on this one...... I grew tired of how hard it was to come up with my injector numbers. This spreadsheet all you have to do is enter the rated flow at your fuel pressure and it will do all the work for you, in the format you need to copy and paste directly into your tune. There is also a voltage multiplier function in there. Only thing out there right now is Siemens data, but it needs modified to work with our cars too.
Next will be an automated universal injector worksheet with all values for any GM format including calculated offset tables. Give me a bit to get that one up and running.
