alright well i have the fmu installed so ill put the map down 1.0 afrs. should i do the whole map down one? cuz that would be a pain. or should i just do the boost half of the map? cuz we only go to 100% load. so say from like 60-70 onward? if that makes sence to you.
also. whats the latency? and of what? cuz this is what my trims are. haha. they are kindda bad

low- 129.688
mid- 75
high- 100

 

oh, should i do both fuel maps? or just the high? and if so how would i tune the low octane?

 

ok i found the injector battery latency but i dont know if i should change it or not. and if i change it i dont know what way to go/or even what box to change

 

Just pull down the 70% to 100% columns ... you might want to look in to adding a 110% or 120% column as well. What type of load values are you seeing on pulls?

Pull down both high and low octane maps. The low octane map should be about .5 below the high octane map in the WOT areas. You are using 93 or 91 aren't you?

On a side note, stock injectors are scaled down in the ECU by 91.6% ... so start there for your injector scaling value.

Yes, injector battery latency is what you needed to find. That's likely causing the mid fuel trim to be off. 14v and 11v are the main settings you might need to play with. These values are essentially dead time adjustments for a given battery voltage. 14v is mostly cruise condition and 11 is more of an idle condition. After adjusting those values, you might want to interpolate the 9v and 16v values by hand.

So, here is your step by step:

1) Set your fuel maps as recommended above
2) scale you injectors to 91% of actual size
3) ROUGHLY tune the AFR
4) Follow the steps for scaling starting at the bottom of this post

 

alright well i had no luck. i reduced the high map by 1.0 and the low by 1.5 afr.
i scaled my injectors to 390
then i logged it onto the car and the car wouldnt idle right. it wanted to die(said it was to lean)
so i messed with the latency and got it drivable around 15.2 afr at idle
did a pull and my afrs were crazy high
so i put both maps down 1.0 afr again
still got the same thing
and i reduced it a 3 time and if anything it got higher. again the values i was putting in were lower then the existing ones.
i couldnt get it so i said f it and put my rom on the car that i get 11 afrs with and no knock, but i guess snow is being predicted here so i had to wrap it up for today

with the fuel trim being out of balance what is the big deal becides it will change the afrs?
any help?

 

well i came up with an idea. should i tune my injector battery latency first? then tune the afrs? becuase would that cause the injectors not to open all the way at wot? just an idea.
if so isnt there a table i can copy and past onto it? because i was looking at that link, and all of the injectors are bigger. or do i have to play around with it. if i have to play around with it how do i know its correct.
haha, alot of questions. thanks again for the help

 

What's the injector scaling value in your working map? I just looked at the lancer definition file I have and the injector scaling seems to have a value of "1," which is obviously incorrect. Also, what is your ROM ID?

If the scaling of "1" is correct, then your value of 390 would be insanely high and that would cause the super lean condition. If this is the case, stay on your old map and I'll look in to getting a correct definition for you, or we may need to rethink the strategy for the scaling.

 

alright well my table for my stock tune is
4.6875 6.12
7.03125 3.552
9.375 1.776
11.7188 0.984
14.0625 0.48
16.4062 0.144
18.6768 0

and then my table with the scaled injectors and droped fuel maps is just to get it to run/idle
4.6875 6.12
7.03125 3.552
9.375 1.776
11.7188 1.608
14.0625 1.392
16.4062 1.008
18.6768 0



i found out that what your saying is true, but there is a way to manuley do it yourself. thats how i got that number for 14v. i just tupe 1.35 into a box and it rounded to that or something.
so was i right with my last post?
tune the idle fuel trim, then the crusing, then do my fuel maps once i get them set to 10% of 100?

my rom is
98720012
and the size of it is around 6kb
(there was a coupe of these made to find the right one i believe)

 

What is the injector scaling value in your stock map?

 

232 in the stock map

like 395 in the scaled map

 

I'd start with a lower scaling value before jumping to the latencies. Use scaling to set the low fuel trims where they need to be, then change the latencies to fine tune the mid trims.

 

but i thought that the stock latencys arnt right because they are for the stock injectors. the bigger the injectors the more ms you have to add
and how low should i scale them to. i went 15% below
?
or should i put the scaled rom back on then lower the scaling?

 

well last night i tried everything. i couldnt get my low fuel trim to move after 4 logs with different scaled injectors.
then i downloaded the data file that was in your link and replaced it with the data file in evoscan.99, and i still got nothing. should i get mitsuloger and log with that so i can figure out my fuel trims?
