click on the Evo Scan datalog... file doesn't do download for you? It did for me but if it's not for your case then I'll be sending an PM soon. Thanks for looking.

Smoothing out your fuel map will greatly improve your consistency when accelerating from any RPM, not just a 3000-to-redline pull. If you overshoot your target boost somehow, you might have a dangerously lean condition above 4000rpm. Overboosting does happen to the best of us, better to prepare for such instances.

Its obvious, the injectors could be dialed in a lil better by the look of your fuel map. Like we have said, ur fuel map is all over the place. The values in your Fuel map are just values, not actuall AFR, but if you have the scaling/latencies dialed in, it should be very close to actuall AFR ~ -.5 difference.
The way you have it, it might give you the AFR in your logs that ur looking for, but the ecu has to do all kinds of work to keep it in range. Confirm what is in the injector scaling thread for your injectors, and maybe try that scaling/latency... not sure if your scaling/latencies from there...
And yes, you can tell if your scaling is off, just by the look of the map. It will look linear when your scaling and latencies are dialed in.

thanks! I got the global scale value = 522 and injectors latency values from an AEM table listed somewhere in Injectors Scale and Latencies thread somewhere on here. But I'll do more looking and improving it.

Good good! Will do but it'll take me some times as I'll have to reset the fuel map to retune the thing again. Should be no problem just need the times.

ok! i just spend the last few days rescale the injectors and the fuel completely. I'll like to thank "l2r88gst" and "MalibuJack" for their posts regarding injectors scaling and latency. Without reading their posts I'll probably fulling all my hair scaling the injectors.
Here is my fuel map. Hopefully it'll be "nicer" than the original on of this threat. I tuned to achieve the same boost and timings level (24 psi peak and 2-13+ timings advance). I noticed that the car is using less fuel now. That's good as it's my dd. Thank you for your suggestion that pushed me to "dig" deeper. Any more suggestion is welcome.
Please see attached the Evo Maptracer image and datalog file.

^ Why you laugh that hard? I've seen worse. I was taking the global scaling lightly hence the fuel map was out of place. So is the new one I posted above better now?
Question... Did you at all read the "How to tune" thread?? I suggest you do so, several times and take notes. Those fuel maps are awful... I cringe at the thought of a 4g63 with a hole in it...

i think your logging too many things. you should reduce that to get more accurate data.
from looking at the pic above i am guessing ur using map tracer to identify the cells u hit. good, but when driving the conditions change (uphill/downhill, partial TPS, etc) u will hit other load cells and ur fuel is only tuned for WOT. i hope ur timing is not the same!
i am not on my "tuning PC" or i would put up my fuel map for you to see.

Question for you... Do you even look at my datalog, which is really matter, at all before thinking of I'll make a hole in my engine?

dont worry about it bro. u will get it dialed in.
