Sorry to quote this from a while back, but I've read that street E85 can vary in ethanol content to as low as 68% and also vary seasonally. Do we need to be careful about that or just trust that the ECU will compensate for a crappy fuel load?

Also, I didn't read this anywhere, but if knock actually does occur, is there a way to flash the CEL or shift light to alert the driver before we actually start to hear it?
