Tuning lower load cells - help?
Ok, so I'm pretty happy with my tune at wot. thanks to a lot of help from evom members, etc. I'm new to tuning but learning a lot.
At WOT in 3rd gear, I'm tuned to about 11.5 at peak torqe then down to 11.2 or so all the way till it gets richer in the end. I first adjusted my afr's then timing, then fine tuned. I'm tuned for zero to 1 count of knock. Most time is spent in the 240-260 load cells. I'm using a MBC.
Now, I want to tune the lower load cells. I've done searches, but can only find bits of info here and there.
1. How do I best datalog in the lower load cells? Its tough to keep things at say a steady boost of 15psi while still trying to drive. Would it work to simply turn down my MBC and go wot?
2. What sort of AFR's should I be aiming for in lower load cells. Same? Higher? if higher, then can you give me a ballpark # to shoot for? ie. At a load of 120 aim for an afr = x at peak torque, tapering to y at redline...
Any help or guidance would be appreciated. thanks.

This is an excellent question.
I have yet to see an organized way to tune the rest of the map in the lower load/part throttle areas.
Currently I am using what another "tooner" had in these areas. I definitely think there is room for improvement in my current map.

One way to hit and fine tune lower cells log tip in(starting WOT) at different rpm levels. ie 2k, 2.5k..4.5krpm. LW3 tables are particulary helpful.
Also by data loging a WOT run( 2-7.xK rpm) in 1st, doing the same in second will give data of different lower load cells. Again LW3 tables rule.
