I just recently got my car operational again after completing an Eaton Swap. I’ve never owned or driven a vehicle that was supercharged so I have a couple questions. These are questions I realize I should ask my tuner but that’s another story.
Do I need to worry about part throttle AFR? I don't have a boost gauge. I wanted to stay with the sleeper look. I've noticed that if I take off at about 1/4 throttle I can hear the beautiful eaton wine but my AFR stays around 14.7. If I take off closer to 1/2 throttle I get more wine and wheel spin and the AFR drops to low 11s high 10s. At what throttle position, engine load, rpm etc: should the computer go from closed loop(trying to achieve 14.7) to open loop?
I thought about doing some data logging and sending it to Tim at Amazon but I’m having trouble actually data logging my AFR.
I've also noticed that my IAT (taken from the stock cobra location in the manifold) climds fast as I coast to stop. Why is that? Example: I'm crusing on the highway and as I exit I take my foot off the gas an coast to a stop my IAT will climb almost 8 degrees. What's weird is it takes longer for it come back down but eventually does. Is that normal.
Moderate acceleration

Here one about 1/2 throttle.

Here is one in 3rd gear. About 3/4 throttle

Here is a video of my IAT as I coast to stop and then accelerate again
