Do any any of you keep records of gas mileage? anybody willing to try mid premium and/or regular gas to check for pinging? any dyno differences? any seat of the pants differences aside from the issue it addresses (side effects)?

Thanks

The only thing the ECM update appears to do is reduce the violence with which the fuel-cut occurs. The fuel cut is still there. It's just much less noticeable. Nothing else seems to have been affected.
