calibration vs configuration files

[tree98]

Ecfg is a file that is basically a "key" that allows c a l t e r m to access the specific engine file it was made for.

Cal file is the calibration file or engine file for the ECM that the engine actually runs on. There are 2 types INCAL....these are the same calibration files mentioned already but in a format that insite requires to flash them into the ECM.

The other is XCAL.... these are the same file again but formatted for c a l t e r m.

You can copy the entire file out with c a l t e r m and save it to your pc(as an .xcal) and edit it however you like and then flash it back in. It's what that software was designed for, its engineering software that was never meant for consumers to get there hands on.

Rawze usually directs people to his mumble server where you can get more indepth about this stuff and he can explain anything you want to know.
