School me some AFR
 

Can someone educate me on afr starting from the basics to intermediate stuff. I'm a boost noon and would like to learn what and how to monitor my afr so I don't blow my engine up.

That is Good info on how the 14.7/1 ratio. How about brain food on what should happen or not happen during various driving conditions such and easy roll on, quick jab, wot, letting off throttle. What are signs ofor something going wrong or about to go wrong?

Some basic infos on Pump gas:
Cruise - 14.7-15 afr
Quick throttle bleep: 10.5-11.5 afr initially
Wot - 11.3-11.7 afr. Run on richer side during hot weather months
Part throttle accelerating - 11.5-12.5 afr
Off throttle coasting - max lean due to injectors shut off
Tune fuel by setting fuel adjustment table to 100 across the map. Then make adjustment to MAF table to get to target afr.
When tuning afr on street, set your timing low to prevent blowing things up if it runs too lean. dyno is required to tune timing.
