Ok. People asked for it, so here it is. Ill update this thread and first post with 5 parts on understanding ECU basics.
This is a PRIMER on understanding ecu functions and fuel trim; not the whole gospel. I am NOT writing ecu code anymore, so I am not the guy to ask about specific table/programming questions. This is so the general forum members can understand the basics of how this stuff works and how to be a more informed consumer. This will apply to vehicles using narrowband O2 sensors and running pump gas.
Understanding this can help our approach to modifications to get better power, drivability, and efficiency; and how i got 23.4mpg on 37’s.
Intake is mopar 77072433; but any well designed intake will work. The key here isnt the exact parts used, but rather the approach. So pick the tuner, exhaust, and airbox that fits your needs.
As reference: AFR vs peak Torque. This is for people under the assumption that running leaner makes more power. If you know thats not true, you can skip.
