ok so a little backround. Im trying to scale 440s on a 3g eclipse. My main problem is constantly rich. Really rich starts im, starting to suspect on of the injectors is malfunctioning and sending them off to testing... ANYWAY, my big question is a fuelt trim scaling question what is the purpose to each latency voltage pertain to? because im really just gettin no support, im lookin on openecu.org and evoM trying to dig up the answer but not really seeing it.
So heres a quote from my conversion thread. So i posted my whole quote. So you can see where i was coming from whe my question at the end.
Yea i started there an it wasnt even close!!! So i used the link steadly posted on the FYI and injector info threads. I took those references and built a bunch of math around them to get some numbers for the lower and higher values to start. But anyway, I was getting knock at 155+ an rpms at 7535 before the car would start, and the steady counts at 28-38 do note the car was still on jacks so maybe the tilt was helping to create phantom knock. Its funny cuz we all are so used to learning, reading, avoiding the lean knock insted of the super rich knock. ALTHOUGH i saw a guy on evoM that logged a knock spike at 255. So maybe theyre logging errors.
so ive been at this injector **** all week. Does anybody else hear any clicking like a valve tick?? YES my oil is not low lol!! Im starting to suspect an injector is bad or something... I say that because ive gone from:
390 to 424
2.808-------------1.848
1.2---------------0.912
1.008-------------0.6
0.696-------------0.48
0.408-------------0.26
0.312-------------0.168
0.12--------------0.04
My current settings are starting to go lower than evo drivers with 780s an such which doesnt add up at all. since i have modded 440s so somethins up.
Ive yet to read a thread about it but i think it would make alot of sense when scaling why the car has values between 4-18 when the car only moves between 13-14. Im workin on some math in excel. So far ive applied the math described in the FYI scaling thread into an in/out cell, so you can type in your low an mid trims and it would tell you what a .1 ms adjustment would do. But i want to expand on it because im not sure but this is what I suspect.
A-----4.69 - 4.152
-------7.03 - 2.208
B-----9.38 - 2.400
-------11.72 - 1.632
-------14.06 - 1.008
C-----16.41 - 0.864
-------18.75 - 0.552
A-mostly idle and a little WOT related
B-mostly WOT and a little idle related
C-totally cruise related
If anybody knows better PLEASE school me. the sooner the better lol

Your latency is what dsm guys call injector dead time. If I were you and didnt know how I would just get a set of stock evo 560s and use the stock settings. But since you already have the 440's try setting the injector scaling to 390 or so to start with and just try adding .140 to the stock injector latency then follow the tutorial to finish dialing it in. https://www.evolutionm.net/forums/sh...d.php?t=302895 Edit : If i remember correctly I posted the stock 440 dsm injector latency values on club3g long ago.

One setting isn't for idle, or cruise, or WOT. It simply is a compensation table for the reaction times of your injectors at different voltages. Injectors react more quickly as voltage goes up and slower when voltage goes down. Some people just tune the two cells for 11.72 and 14.06 V, since those are the only two you are really using during driving, but I would always scale all of them, so you keep the shape of the curve the same. To keep it easy, adjust all of them by the same amount, so you are simply shifting the entire curve. This way your injectors will be scaled correctly for whatever voltage your car is operating at.
As far as why the other voltage cells are there, I would guess possiblly for cranking where voltage may be low, or just for general voltage fluctuations that may occur. I'm sure there are other reasons as well that I'm not thinking of.
Edit: Just because graphs and pictures make it easier to understand things for me, here is the graph of the stock Evo injectors, voltage vs. latency. This shows how the latency changes to chaning voltages. When you scale and tune injectors, you want to keep this same basic shape, so you should be tuning all of the cells.
