What is your idle rpm and timing settings?

I can get you my scaling/latencies, but I believe I run 8/6 on the trims. Ended up leaving it at that. My AFR's bounce between 14.6-15.7 while idling, mostly stay above 15. Cruise bounces between high 14's and mid 15's.

I figured this fall I would play with it more and try to fine tune it. I am still having warm start issues (having to give it gas and crank it extra) on e85.

What are you guys running for your crank enrich ipw tables?

I did bump the idle up to 1k, and I run MAF w/ ARC intake box. I am going to start running SD in the future.

Idle rpm is - 891
Here is my timing map:

Hey guys, Ive been trying to scale those injectors for few days now. I am posting inj scaling, latency, Airflow Hz(maf), and timing map. Do all the values look ok to you? Is having 255 Maf scaling ok on idle?

My trims are:

LTFT Low: ~0
LTFT Mid: +1
STFT: -/+ 5%

The timing map just used from my prev evo with similar mods; is cruize timing high? ( i have afr jumps/surging during cruise )
I did up the idle timing to 13 after took this pic
Let me know if something doesnt look right. Can i proceed to the next step of tunung here?
Thanks for any advice

Anyone has any input if the values look ok?

Go for it. Your trims are about as perfect as they can get. Strange to see you needed to do so much MAF scaling though. All you can do at this point is give a pull a shot and see how she does.

Hello !

I tried with that scaling which seems to right if you take look on it, but my fuel trims are mad ! The car idleing and cruesing lean, stft +25, idle trim + 12.5, mid trim +12.5 :O With stft +25 and idle trim 12.5% the idle also lean 16.5:1 on the wide band ! IPW at idle 1.8 , Injector duty cyle 1.5 % . Funny but the WOT Afr is right ! Intake and maf is stock but from other mitsubishi and with the right scaling.
Fuel trims were in line with the stock injectors. Any idea where is the problem ? Need to adjust the minimum ipw ?

How do you get the scaling to go above 1271?

I think the next step above 1271 is 1329, just write in .
I dont know why but it is not working with pump gas... At wot the injectors are perfect, at cruesing not bad but the idle the wideband cant show anything because as lean... If I bump up the latency at 14volt from 1.17 to 1.440 :O :O than I have well idle with the help of closed lopp correction, but the cruesing afr is rich exspecially when you accelerate in the closed operation. In open loop bumpy idle and so rich evervy where.

I also played with the minimum ipw settings, set it to 2.17 with the right scaling as Applaud posted. Soo rich afr everywhere but stable idle at 1500rpm Afr is 11.8 ! Cruesing afr in open loop is 12.5 Funny..... Any idea ?

Will try with E85

I feel up the car with ethanol, but the idle and part throttle was bad too... So I'm starting to play with the latency. Interesting but now my trims are in line ! Idle is and cruesing is right too ! I dont know why is that big difference.

Scaling : 1044

2.784
2.112
1.68
1.68
1.488
1.224
1.032

The issue was same on pump gas too.. If I increase the latency I have idle and good afr.

I am glad everyone is liking my latencies. It took me FOREVER to get them right. Once they are set, simply mess with the scaling to dial in your specific setup. For large number scaling you have to hit the = and type in the value you want. It will interpolate a little for you.

I highly recommend that before you attempt to mess with these 1450cc injectors that you have your MAF scaling spot on. Otherwise you will have little "issues" with getting the 1450s to run well. Also, it is imperative that your battery is strong. If you are running a mini battery that is a little older, I guarantee you will have issues with these injectors. They need strong voltage. For this very reason I ditched the mini batt and put an optima in the trunk.

oh and my MAF is scaled differently because of having a different intake. This could be part of the reason for the differences.

The latencies should get you in the ball park. Play with the scaling to get you dialed in.

Thanks guys, my next question is when I have my scaling with perfect low and mid trims my wot runs lean. Even with leanspool disabled and 120 load and up all blocked with 9.0 in the fuel map I'm seeing 13.0?

But if I lower the scaling to 8.5% and block the afmap with 11.0 it'll read 11's.

I know the numbers in the map are just numbers but in order to get the right afrs I have to drop the numbers into the 7's on the map. pump gas.
