Well I was doing some research about my blown sub and ended up calling a Mazdaspeed tech in Ogden Utah about it. So at the end of the conversion I asked about the ECU flash just for Ha ha's. He told me that there already is a flash out, but its for people who are having CEL's. I guess there have been a few people that have come into the dealerships with CEL's that are being caused by being Overly Rich. This flash is virtully the same as the one coming out for us but was intended just to fix this particular problem. He did seem to know what he was talking about from my perspective but I don't know much about engines so I figured I will put it out to you, the pro's to ponder.
