Thankfully no codes ... WebSTFT-based Doppler velocity estimation cannot simultaneously maintain high spatial resolution and velocity resolution. It is commonly referred to that Doppler velocity resolution and spatial resolution are coupled. Based upon the restrictive definition, STFT lends itself very well to a pure nonstationary signal. raymond schefer https://ods-sports.com

LTFT is slow so if it is able to keep STFT around 1-2% the MAF curve is accurate. If this is the case, why would my STFT around 12-14% ? Second question : Ideal WOT AFR should be around the mid 12's. Why would it be mid to high 11's ? I'm thinking this is related to my first comment. No pending or CEL. Thanks.
