I have reflashed my ECM a few times with differents tunes trying to find the one I like and each time it is only reflashing 96K. I thought each flash was supposed to be 512K. Am I not reflashing the whole file?

And there are two upload buttons. One to upload current calibration and one to upload an OS and a Calibration. If I push the button for the OS annd Cal upload I get a warning about doing a full reflash.

So what will a full reflash do?

Sorry about the newbie questions guys!!!

It is only necessary to do a partial reflash to change tunes. If you go to a custom operating system like DSP 5, (Switchable tunes) or something like that, then it is necessary to do a full reflash. Otherwise full reflashes are not needed.

Kewl! Thanks! I have a DSP2 that I will be installing soon.
