ok so here are my current maps. would like you guys to take a look, provide some insight.

i dont think i have touched the high cam fuel at all. just how it was?
here are some logs...
(https://realhomemadeturbo.com/forum/proxy.php?request=http%3A%2F%2Fi276.photobucket.com%2Falbums%2Fkk32%2Fefssuck2%2Flog2_zps59236cb4.png&hash=4c90e538439496b149bdd56f1162c26136dce060)
think this pull was legit... i do notice that VTEC is set at like 4000rpms, and seems to cut on an off for a couple 100 rpms. notice its off right there. then turns back on and stays on.....according to the log window anyway.

ok, i think this is one of the ones i had issues with. i think. might be the other one. dont really remember. but it would cough/fart right at the end of the pull, well, where i would shut it down.

wtf? kinda having an issue with this one. notice the trace, notice the RPMs in the top right....wtf?

Lean it out a lot. Any misfire will let lots of raw gas into the exhaust, and the next valve to open will burn it. You can also lean it more in low boost than you'd run in mid-high boost. There's enough back pressure while it's spooling where you don't need the extra gasoline for cooling.
As for vtec, crome log probably judges if it's on or off based on RPM without hysteresis. Since rpm will always bounce a little, it goes above/below the engagement rpm. Otherwise you'd have to add another 100-200 rpm between vtec engagement and disengagement.
As for the high-cam fuel map, that's ideal and I hope you copy/paste it to low cam. :P
-
I remember Dave saying that he liked to run 13ish for the first lb or 2 of boost because it helped the plugs stay clean as it was ramping into boost. Set your target afrs, and then do some driving and then go back and interpret your logs, make changes, and then do it again.
-
That's what I do. Mid-low 13's till well into boost. Then 12 till about 10psi. I go richer as psi increases after that and adjust with plug readings. I imagine its probably a combination of engines needing different afr and widebands not being the end all be all, but it varies where I am under the same psi conditions

ok. i guess i will update this...
i am no longer running CROME PRO. im running an AEM EMS, 30-1040 box. been running since christmas.
had a glitch with my map that showed me maxing out my fuel. with some JD help, i got it fixed it looks like. so i went for some more tuning. needed some re dialing in of the map for the rescale.
so everyday i seem to learn something... and today i noticed this...

i checked my KS log on this pull. as you can see, doesnt look like its all happy. (oh, i learned that this works. and i was looking at the wrong KS reading too)
AFR's arent on that plot cuz it only lets me do 3 at a time. dont remember what they are, but seemed fine (O2 feedback is setup). only did a pull to.....well fuck i just did a pull, i dont have a tach lol. from that it looks like 5800rpms. getting erratic shit from the KS from 4700-5800. most the time its below like .5-.6v
here is #3 before you ask...

they all looked fine, the same.
took little over 1 deg out that area, for now.
btw, im sure JD or someone will as, or want to. but its a Honda B-series KS. cuz thats what i found. wire is shielded (honda 02 sensor wire).
thoughts?

you can add any sensor to the logs. It will just be an overlay on top of any of the 3 already shown. When opening a log, click the "overlay" button, choose sensor/reading, profit.
