Fuel packet initially targeted to enter cylinder just following overlap period by retarding the end of injection lower slope) while the beginning remains static
2
If EVC @ 0.050” to piston intake BDC “window” is full, then we have no choice but to advance beginning of injection (upper slope) while the end remains static
3
All calculations take into calculation fuel transport delay, however we cannot do anything about the fuel puddle remaining in the port

1) System Parameters – Engine Parameters – make sure “enable injector end able table” is unchecked and Injector End Angle is 0-82.9-61.2-39.4-28.4-31.7-36.6-42.8-47.8-52.2-55.8-58.9-61.8-64.2-66.3-68.3-70.0
57
2) Add advanced tables ICF if you do not have it-90.1-70.8-51.4-28.4-31.7-36.6-42.8-47.8-52.2-55.8-58.9-61.8-64.2-66.3-68.3-70.0
58
3) Under ADVANCED select 2d Tables, Under SETUP check the “Enable Table” to turn the table on and call it “IEA offset”-97.3-80.4-63.4-37.2-31.7-36.6-42.8-47.8-52.2-55.8-58.9-61.8-64.2-66.3-68.3-70.0
59
4) Under SETUP make the X axis “RPM”-104.5-90.0-75.4-52.8-31.7-36.6-42.8-47.8-52.2-55.8-58.9-61.8-64.2-66.3-68.3-70.0

6) Under SETUP make the Table Type : “Injector End Angle Offset”-118.9-109.2-99.4-84.0-31.7-37.6-42.8-47.8-52.2-55.8-58.9-61.8-64.2-66.3-68.3-70.0

7) Manipulate this sheet however you see fit, but it should be fairly close to your use just from putting in your cam specs-133.3-128.4-123.4-115.2-31.7-85.6-64.8-47.8-52.2-55.8-58.9-61.8-64.2-66.3-68.3-70.0
64
8) The “upper slope offset” moves around the numbers closest to zero. Try numbers between 0 and -90. This affects WOT.-140.5-138.0-135.4-130.8-44.7-109.6-94.8-78.8-62.2-55.8-58.9-61.8-64.2-66.3-68.3-70.0
65
10) If you zero out “distance from injector to intake valve seat” you remove all fuel transport delay calculations, large numbers will advanced the table a lot-147.7-147.6-147.4-146.4-63.9-133.6-124.8-114.8-104.2-92.8-80.9-68.8-64.2-66.3-68.3-70.0

67
11) Injector dead time should be at whatever voltage the engine normally runs at, at 1 ms it will advance the lower slope 3 degrees at 500 rpm and 30 at 5000 rpm compared to not accounting for it-165.7-171.6-177.4-185.4-102.3-193.6-199.8-204.8-209.2-212.8-215.9-218.8-221.2-223.3-225.3-227.0

12) Copy the Y axis (select D30 to D45 with your mouse, right click, copy) and X axis (F47 to U47) into the advanced table. -140.7
70
13) Paste into either the advanced table top cell for Y axis, or the advanced table left most cell for X axis-159.9
71
14) Copy the entirety of the table (select F30 to U45 with your mouse, right click, copy) into the top left cell (right click, paste) of the advanced table-188.7
