So in waiting for my tuner to actually tune my car, I decided to be on the safe side I'd try to add some more fuel to my tune so its not this lean at WOT.

I've added fuel, but looking at my IDC, It looks like I may have to wait and have him turn down the boost





I've ive tried adding fuel, but it doesnt seem to change my AFR's.. looking at IDC, Im thinking I cant add any more?

Please help this noob, My first map Im posting.

Forgive my ignorance I'm used to accesstuner racer. Are you really getting that much knock with your afrs in that region? Because those afrs don't seem off for a wot pull.

Knock sum shows 0. Curious what you are looking at? Maybe the Timing column? Or am I missing something..

Isnt 12.3 a little lean for WOT? I always thought I was supposed to be around 11.5.

I let off at about 6k after seeing the 12.3 AFR

From my understanding, it looks like you're right in that you've maxed out your injectors.

Oh alright yeah I was looking at kr volt. Your injury duty cycle is over 100 isn't that way over their peak efficient range?

Toekneee!

Fuel pump and injectors?

Yes, your fuel system is not up to the task at the moment. Get a Walbro255 and that will help. I also wouldn't run 26psi on a stock intercooler with 91 oct.

Looking at some older logs, It looks like I am over boosting compared to what my old logs show.. But this only solidifies my decision to have someone else tune the car, As the last tuner didnt include any boost error correction. The table is 0'ed out..

THANKS guys.

Glad I was actually able to piece all this info together.

Zero-ing the table isnt a sign of a bad tuner, but if there are other reasons so-be-it, that is a very small detail.

It needs a fuel pump or fuel filter change. Shouldnt be out of fuel on a stock pump and injectors at 104% unless its an VIII or dropping pressure for some reason.

Totally understand Aaron, but correct me if I'm wrong, isn't that kinda the point of ECU controlled boost? so it can automatically adjust for things like this?

That is the point but he's saying it isn't the problem. Worry about bec when you fix your lean issue.

Altering the duty cycle is easy and you will want to check the 3 port configuration before raising or lowering . Different methods of boost control place the ports differently. Block vs bleed so on so forth..

No, ECU controlled boost is to have something cooler than an AEM tru boost that is one duty cycle with no feedback (no correction) for all RPM. ECU allows the car to run at different duty cycles vs rpm to keep taper away in some cases or boost spikes away down low.

The error feedback even when set to 1 is not fast enough to keep it even. I arrived at this A LONG time ago, but there are many that have given up on it in the meantime. It still doesnt correct for altitude changes fast enough to make it worthwhile. I run straight duty cycle and a boost cut. If it has no boost cut that is a totally different deal.

Boost cut or fuel cut load? I don't see a boost cut in the global boost setting.

Boost limit under "Turbo boost Non-JDM"

hmmm must be different v7 xmls floating around. I still don't see it.
