So months and months I am on the process of getting a tephramod map working on my car properly.
so far all features have worked except the immobilizer which i just disabled it.

But my main issue I am having is when it comes to logging, 2500rpm, third gear, I foot down on the gas and the car quickly dips from 14.7 afr to 11.3 in a split second and tapers down to 10.9 by redline.
after that happens, and i release the throttle, it takes a spike and either idles too lean (18s) or too rich (11s)

I don't understand what is going on as my fuel maps look all good and the car drives perfectly okay if I'm at the right gear at the right time.
