JB4 G5 Iso Map 5 40% e85

So I have been running hex20 Map 5 e85 40% for months zero issues.
Last night I started to get the CEL after some wot in 3rd gear. Figured this morning was a good time to run some logs.....seeing that I didnt have my laptop with me last night at 2am.
Today ran 5 logs. one with 2-4, 3rd and the rest 4th gear pulls. Today Im not getting the solid CEL, but instead 1/2 engine light and reduced power.

here are some logs....

It's all covered in the JB4 E85 notes. For 29F2 lower open loop or add the free back end E85 flash.
