Stock car with OFT E85, LTFT spiking negative?
 

I haven’t seen any logs with quite the same issue I’m having, hoping anyone can offer some insight?

This is about my 3rd tank of e85, everything seems to be running well, IAM is staying above .9 (seems like when I get to 1.0, i eventually get some knock?). LTFT stays just below 0 most the time, but will randomly spike to like -15, but quickly returns to where it was.

It seems to coincide with letting off the throttle. Is this normal? A log of some freeway and street driving is below.
