Yep that's for diameter. 11.1% and 16.6% were for cross-sectional volume.
I think there's some concern about slowing exhaust velocity, but for something like an E85 build that's guaranteed to flow more air, I think the benefits would be worth it.

Can someone please check my log? I am on my second day on e85 and am wondering why my fuel trims are so negative? I have gruppe-s UEL Catless header and overpipe.
Thanks guys https://datazap.me/u/luc898/log-1610058698?log=0&data=1 |

probably just not real e85 in your tank, maybe something more like e60

Hey thanks for the reply, i think i tested it at about e70 give or take 5%, does it look like it is going to have a negative effect on my engine? Or do you think it should be okay. Sorry im pretty new to tuning. Havent noticed any issues in how it runs was just concerned with fuel trims. I can also smell my gas at high rpms when on WOT im not sure if that just cuz catless headers or not. Thanks ALOT

Before you edited this you said you already reflashed. There's no proof that the maf scale was wrong, so now we can't collect any data on what would have happened to the trims. Again, if the LTFT had levelled off at 3.91 @ 5200 rpm instead of climing another 4%, the AFR would be perfect. Changing MAF scale is only going to skew the area that's actually working correctly.
FYI openflash disable/limit trims to US fuels and they give MY17 black manifold cars the same tune as red manifold which obviously runs like garbage with so little timing. Zero shits given to anyone outside US. If you're unwilling to do the km, there's no point trying, however if you do want to try to fix it for real I can email you the files, but you'll have to start logging after 200km and do at least 1000km on the first one. |

Anyone see anything funny in this datalog? Fuel trims are high negatives in idle but AFR stays normal. Fuel trims are within spec as soon as I start moving. |

trims aren t good even when you start moving, usually too negative trims is due to a vacuum/boost/intake leak
possibly after the maf or, a bad maf scaling /SD scaling your average -20% of fuel trim looks like an intake leak |
