A word of warning...
Personally, I would like Mazda to provide dyno graphs with AF readings of a stock MSP before and after the flash before I have my ECU flashed. I think JoeP made the point, once you flash, you CAN NOT go back.
Mazda is working on a "fix" for our problem. It looks like they are going to provide a "fix." Right now, no one knows what the new ECU code does. Let's wait and see what happens. Mazda must be a MSP for a beta tester. I would like to see them strap it to the dyno and show us how it performs.
I would be inclinded to guess that we might see peak torque and HP drop a little.
