I know the dealer flashes through the OBDII port with a j2534 pass through which is pretty easy to get. So it can be done, Mazda has just gone to great length to keep it from happening.

Dex, thanks for your time! I've spent the last week trying to decide what my options are and I think I've pretty much run this to the end of the line. I don't have time to learn the process and then go through the process of creating a usable definition especially with nothing to compare to. Unless ...

As it turns out the J3 port is basically disabled by Mazda so the Moates equipment won't work anyway. This is getting harder and harder...

Thanks for the reply! I figured it wouldn't be a hardware issue. My guess is that the definition is the problem. My understanding is that I can go through the hex and do this myself. I realize its much easier said than done, but am I missing something? Also, is the quarterhorse a good tool for this ...

Hello, I'd like to be able to use the Moates equipment (quarterhorse, F3, J3, etc) to tune the ECU. Moates is telling me that it has been tried, but that it was unsuccessful in the past. I haven't heard why it has been unsuccessful or how much effort was actually put into it. I don't give up easily,...
