I'm working on two problems. However, I'm sure you will find others. 1) lean spike on quick initial throttle movement; and 2) KR under boost but it is not constantly happening. I'm a beginner with tuning and efi live and I'm struggling to get any further with my tune. I have attached the current tune and most recent log file.
Problem #1 - I think I'm slowly working it out by increasing B3426 and adjusting B3428 to blend the rich spike into the normal commanded fuel. But please, any more tips would be great.
Problem #2, I have NO CLUE what to do.
