Open Loop AFR leaning out when hot

I'm running e85 on an open loop tune. During idle and cruise, one thing I've noticed is that as soon as it gets hot outside and I've been driving for a while, like over an hour, and IAT's are 100+ at idle, the AFR leans out. I try to keep AFR between 1.00 and 1.05 lambda, and that will hold perfect until it starts to heat up, then it creeps up to 1.10, and sometimes higher.

I scan fuel pressure, and that does not change with the heat. MAF values and timing do not change either.

Is there some other table that is not visible in HPT that could change AFR based on IAT's or some other parameter? Any other things to check?

Hot scan and normal scan are attached. These scans were run on the same tune and same tank of gas, but the hot scan was after driving a long time and heated up, and the normal scan was from a cold start through normal operating temps.

weird, Ive noticed this as well, but never looked into it.

This guy did once,
Russ K: "Since these cars don't yet have an open loop table like the V8's and the V6 (4.3) trucks, the commanded AFR while in open loop is all over the place when not in PE. In PE the commanded AFR will be were you set it."

^^ Beta version gives us these tables now. We got the multiplier and commanded in there for OL in the 6's
