Alot of the information that I'm hearing is that COBB doesn't even know how to read the information on the ECU. They don't change EVERYTHING when they remap your ECU, alot of the information is the same and they just change a few peramiters. Just a heads up though, our CPU's in the ECU's can only handle up to a max of around 150 flashes. That is an estimate by mazda, so some might handle less and some might handle more. For most people that will never be an issue, but I don't like that. Anyway, I'm not a fan of COBB, I think they try to work on the Speed3 like they do with EVO's and STI's and they can't. Its a different animal. I'm so happy I found CP-E.
