Winter blend gas and E/85

I love it when I get a response from torrie after reading that log that says "There is room to make more power there."

I wouldn't let that stop me from continuing the log/retune process all winter. I've had 3 revisions since last week.

I'm not going to stop, I just can't measure the difference in real time it's all seat of the pants. I took the car to the store this morning and it felt faster in the 58 degrees this morning than it did last night at the track @72 degrees.. I aired the tires down last night also, on the way home low pressure light came on.. Car went to fwd mode right away.

Wow you say winter gas is worse then summer gas?
Looking at the learned octane ratio on torque in winter worse I get is
-.9 in the winter on 91 octane now it's summer and getting -1%

Seems winter blend changes from our cheap but popular convince gas station was getting .4 and Chevron .9-.6 but now summer it's a flat 1% from both
