Switched on to the E85 PI map and trying to run with straight pump E85 and a fuel it TBI. I do not have the logs to upload offhand however I can tell you the AFR is pretty steady and overall looks healthy.

The only issue I am getting is a a solid SES. code is a part throttle lean code. Thinking the fuel tables at part throttle are a touch too lean for E85 straight from the pump. Any suggestions? I topped off my tank with 3.5 gallons of 91 to see if my suspicion is correct.
