    '15 Coyote tuning, setting up for boost

    What are the limits etc that need to be setup for boosted cars to not clip/code/otherwise upset the model of things? it looks like I should disable CylAir Anticipation under Airflow/General/Maf Calibration, but what about MAF Limit, CylAir WOT Multiplier, CylAir Max Mult. and next to it Desired Air Mass/Initialization, Chrono, and Max Load, or IPC/MAP Maximum?

    Any other areas that need ceilings raised? If the uSec MAF reading gets near the lowest number you have to move the Default to a lower value than it correct? (Say your at 93uSec you might want to set default to 85?

    Is there a way to force the thing in 100% open loop so I can log target vs actual EQ error and trim the MAF curve accurately without LTFT STFT interfering?

    I noticed in this thing the MP are always 100% weighted to 14 as well?

    Also noticed ECM 28141 Aircharge Multiplier has a bump in it up to 1.09 around 5000 rpms at MP 14, where OP and most of the rest of them are just 1.00? Is this Roush way of enriching that area? Should I set to all 1s (and prob have to change MAF curve to get a/f right in compensation)
