Very nice
Is this the evo ecu?
^^^acually it's a stock modified PCM... Because no other stock PCM has what yours has ;)

Thats evoscan log.
Evo scan long on live tables usual picks up loads and rpm the pcm hits constant this speed up data log. If you log evey bit it becomes slow and big data
The idle pcm trying really hard to make up for the boost leak. But she need the injector dial in 100%
niiiiiice strong idle. lol wtf rpm are you seeing 100% load at? haha

Bro wth?! Haha I am so waiting to see a pull on a dyno or a virtual dyno graph. :)

Got a question on your head gasket. Are using the 4g64 or 4g63 87mm head gasket?
Ok guys. With a few research and some calculation. I got a base data for the FIC injectors. I compare the 2.0 evos scaling and latency for FIC 750 and 720 and added 20% more to compensate for the extra displacement. It should bring me close on my fuel trims
excel preview that i made for the 2.4L 87mm. This is for my setup.
That is a very nice layout! You are correct on the 20% number thats for sure

Nice! I used your excel layout and the 3.5L compared to the evo.
I did 3.5L / 6 = .583 * 4cyl = 2.333L ~17% Would this be correct? lol!

Yes. Now that should give you a base. U need to reduce x=% fuel.
Use gts maf scaling and smoothing
And bump the injector scaling by x=% of the stock evo. Increasing it should reduce fuel
* i notice your calculation is a little much. It should be less percentage due to the limit of the 560cc and ecuflash.
Very nice, thanks =)

Keith i made some raw calculation and came up with a great formula for injector scaling. This should help you. Like i said base to get it start it. Then fine tune the after that. Check this out
We have a fuel pressure of 43.5PSI with vacuum it goes down to 38-40 depends of your CR. SO:
38psi lets say for most application. Mine is at 40psi
38psi/43.5psi*100 = 87.35% so the rest of 12.65% this is what you do
You have evos 560cc injectors your calculation will be
560cc-12.65% = 490cc in ecuflash calculation is 513cc Final tune by Mitsubishi *for EVOS*.
So now. Your bore is 90mm evos is 85mm. 90-85= 5% "mine doubles triples because of the stroke" evo is 88mm compare to your 85.8mm" making the 4g64 100mm stroke. Making it 15% 20% more fuel.
So now we have an % remember this is ECU flash injector scaling fueling. Evo will flow more air per cylinder because of the stroke of 88mm that is why if you put evo injectors to the v6, injectors will flow more fuel making your AFR rich because of the stroke with 513cc scaling.
Final calculation. 490cc+5% 514.5=515cc, this is a base depends on the head flow and mods. In ECU flash there are constant values that default by the formula and Mitsubishi code formula.
Your base 515cc on ECUflash will be 532cc evos is 513cc base on the 490cc calc
if you see ecuslash scaling and you use the [] you will see 496cc making too rich default evos mitsu made it 513cc after their final tune "still made them rich to save knock", yours will be 532cc after your 515cc calculation we made.
Hope it helps. you need to leave it at 532cc as base it should get you close to +-3%. I would use the GTS maf scaling and smoothing and work for last after you get your trims down to -+3% or so with scaling and letancy.
532cc scaling *increase will make you leaner*
-5% from latency of stock evo *decrease latency will make you leaner*
Very nice man! I'll save this to my records =)
My base fuel pressure is 48lbs without vacuum and it goes to 42 with. I should turn it to 40 then and start tuning from that. Thanks bro, hopefully I can give her another go this weekend lol. I about finished my wire tuck and have to figure out another way for my intake to run before I try again.
