So, you want to be a tuner? Look no further.

I'm in the process of retuning with the new motor. I got my idles set up properly and my 1.5-4k band logs look good except the 2500 rpm band.
After 4-5 logs, they all are showing the same thing: wildly bouncing around. I took a 50 second log on a nice uphill section at 37mph. Minimum STFT is .62, max is 14.66, average is 6.38, and standard deviation is 2.46.
See my attached screen shot.
Any ideas?

That's what I was asking about. The numbers I described were for the 2500 rpm log only, the rest are spot on.
Should I just ignore it since it is isolated to one rpm band? On the flip side, how do you adjust items on a single rpm band? Fuel VE?

I dont see any option for launch control in the accesstuner race for my 04
rx8 (AT). I wanted to raise it. My car seems to cap at about 2500-3000rpm
while braking and accelerating at same time. Is there any way to raise this
to about 4-6k? Thanks

How many cycles do you need to run to get an accurate log of AFR's? Reason I'm asking is that these two maps are identical from 6000RPM, but logged AFR is far leaner at the current R16(Yes I have been fiddling a whole lot) than on R8(purple). Red and green are same map, just two different pulls, green uphill, and red on flat surface.
Air temp was approx.25°C(77°F) at purple, while now it is 10°C(50°F) or slightly less. Rainy.
I have ran 2-3 cycles(during one day). Should I run some more before changing? Any other tip or tricks?

Load matters, if I loaded my map right now and did 3 consecutive logs it would be similar. Your not on a dyno so their are two many variables that can cause this thats why we take the avg for RPM bands and compare to actuals to determine the differential. Those are what you need to look at.

I'm not sure if I understand you correctly, but this is more or less at the same load, WOT all the way. So when I change AFR over 6k, and all loads(same values for all loads), and it doesnt go richer when map is richer, I dont understand whats happening.

Discovered that I did a mistake, I did take it two steps leaner than the old. Made a new one, but one richer than the old, and it seems to be responding as expected. See pic. My bad, sorry.
I change the fuel tables. Previously I have also changed dwell time(oltmann) and Throttle fuel tables. Removed a notch that I did not see the point of, see pics.
One thing I notice is that it goes very rich over 8500RPM, is this a known behavior?

I hate to be the noob here but... this seems to be the most active tuning thread. Im trying to figure out how to up the OMP rates and change the fan speed with my Accessport. Im working on my understanding of the OMP rates currently. Attached are the stock and modified load based values. I multiplied all values by 1.3 or 30% and then changed anything over 60 back to 60. Did I do this right? Additionally, do I do the same thing for the throttle based values?

Yes, the stock fuel maps are very rich at high RPM and loads.

I was wondering if there is a limitation in the top, that say "This MAP is too lean, I use some other default values here in stead".
Basically, I get more or less the AFR I ask for(-ish) in the map, but over 8500RPM AFR "nosedives". See pictures
Regarding scaling; I have actually not changed anything. I checked LTFT, and it was quite low, 2-3%, I believed that then I was good to start tuning. Incorrect?
PS! It seems like my SSV is stuck, But I'd recon that this is not what causing it to go rich at this RPM.
