Your turbo takes longer to spool than the K03, I think you're going too rich too soon. From what I've been told you want peak enrichment at peak load.
You're so right, I gleaned that from your stg1 thread after I posted up my log. I'm going to start from scratch and see what I can come up with. I'll have to look at my load graphs, but I'm thinking that ramping it up between 3000 - 5000 would work well.
Your log is all messed up due to opening it with another editor and saving it with that editor
Sorry about that, I took two logs and forgot to rename the second run so I just cut the data out and saved it not knowing that it would hose things up.
Based on your EGT temps and current state of BTS enrichment, I would update FBSTABGM to a value under 1 at 950c. Add a larger value after that for safety, and if you plan on using LAMFA for fueling otherwise, I would set the first column to 0.
Code:
889.99 939.99 989.99 999.99
0.00 .90 .95 1.0158
Of course, you will want to review the values in KFLBTS to make sure they are not set too rich in the higher load/rpm ranges. Set the values in this table to what you want to see and then use FBSTABGM to enrich even more once the temps get too high. Or, you could ignore KFLBTS all together and just modify FBSTABGM to get what you need. There's a couple of ways to skin this cat.
It appears that working with FBSTABGM is the simplest way of working with this, for now, and I'll apply your suggestions to the next revision (thanks, btw!). However, is this the correct way of going about it, or is there so much variability that there is no "correct" way? I like to learn how to do things right the first time.
Your egts will come down a bit when you advance your ignition timing a bit more. you have no CFs, so you have room to advance the timing a bit.
I'll get after that once there is a consensus that my fueling is good.
Don't forget the DLBTS!
from the S4WIKI
KFLBTS_0_A - requested lambda for component protection when calculated EGT is above TABGBTS, scaled by FBSTABGM. Note that lambts also modified by [KF]DLBTS and KFFDLBTS: lambts = KFLBTS + ([KF]DLBTS * KFFDLBTS). Therefore, setting KFLBTS to 1 where you don't need it won't disable bts, you also have to set KFFDLBTS = 0 to disable bts completely.[20] Note that Mbox has DLBTS (2D), not KFDLBTS (3D).[21]
TABGBTS - Threshold for KFLBTS. Unless calculated EGTs are above this threshold, KFLBTS is ignored. You may have to lower TABGBTS if you have a scaled MAF, since calculated EGTs will be artificially low.
FBSTABGM (0x150C2) - KFLBTS multiplier. Make sure you change the axis properly to represent your lowered TABGBTS. Again, not necessary if you have a properly scaled MAF.
I'll have to read through this about 20 times to make sure that I totally understand it.
