I found a Gen 3 eoit spreadsheet, and tried to convert it to gen 4.
maybe someone can fix it. =)
i tried on the conversion. i kept getting "42" as the answer
The most hated, make the most power.
93 Ranger. 5.3 D1X. 1069hp.
If I wanted to End my injection at the BDC, what numbers should i aim for 540 right?
so i could just add 20 to my boundry and zero out the other tables...
I think i'm getting dumber the more i look into it.

DSteck,
1) How do you usually do the ECT table? Do you still want it to pray fuel on the back on the intake valve with overlap? or just spray it at the same time no matter the ECT?
2) Any hints on how to manually add the short pulse adder and volt offset?
3) I think I'm almost done with the calculator i made from scratch can I email it to you and see if its correct?

1) Leave it alone unless it prevents me from delaying the main shot when I want.
2) Look at the tune values in the tables.
3) Sure. dsx dot tuning at gmail dot com

Well that's what I was thinking as well, but I believe you have to allow some time between the Normal EOI and the boundary for the makeup injector pulses. Therefore you need values in the tables to allow for that time. Unfortunately I still don't have an explanation of the purpose of the makeup pulses.
I put together this worksheet to see how injector on time corresponds to valve events. Basically the yellow cells are user inputs. Just put in your valve open and closing points as you would find them on a cam card and the sheet converts it to deg ATDC firing as is the convention for HPTuners injector timing tables. Then enter your injector pulse width and RPM to convert the pulse width to degrees. Then enter the Boundary, Normal ECT adder, and Normal RPM adder. The sheet calculates the normal EOI and the SOI so that you can compare those events to the valve events.
ok, see if i did it right, looks like i need to add 60 to 800rpms and below. will need to do some more logging to monitor pw and map and voltage
I'm assuming the start is based from 720 TDC, since it goes down if i add to the normal rpm.
thanks!

SOI and EOI are both in degrees ATDC firing. EOI = boundary minus Normal ECT minus Normal RPM so if you add to the normal rpm, the EOI and SOI will occur sooner (lower number) If you want to inject later, after the EVC, then add to the boundary or take away from the Normal tables. Which is the best way to handle it? I'm still unsure.
hmmm, interesting, i always thought different.
i think its either subtract from the boundary, or add to the normal, to make the injection finish later. both end up with the same value
stock
520-110 = 410
30 added to normal
520-140 = 380
30 subtracted from boundary
490-110 = 380
that's how i understand it, the lower the number, the closer it gets to 0/720, the end of combustion process.
maybe thats why i'm so mixed up, maybe im thinking gen III stuff? i dunno
p.s. dave i love you.
I'm just waiting on DSteck to get back to me on the spreadsheet I sent to see if I'm right. If someone wanted to make something that would automate the process of adding the voltage offset and pulse-width adder that I can add to my spreadsheet, I can't seem to figure that out to save my life.
Im thinking though why there needs to be a 110 in the normal operating temps, why cant you zero that out to give yourself that much more room to inject it. So in mine that is 0 and the RPM pretty much just takes on the 110 at lower RPM.

this is what i was trying to explain.
its probley 100% wrong
-Carl
ps. the only reason i think this is because it injects against a closed valve stock
If you zero out the adders, you leave no time for the makeup pulse.
