I'm trying to do a full flash to a E38 ECM using a .cal I downloaded here. Winflash is not letting me do the flash, it says it's incompatible. I checked "Full Program" but didn't help. The cal opens fine in the tuner program.
I can flash the same .cal I read from the ECM, just can't flash other files I read from other ECMs or download from internet. I'm aware of the risks involved with flashing E38 ECMs with a different OS, but I have no choice. I'm trying only 2007-2008 .cals since this ECM is a 2007.
This is the first time I try to do this, I always edit the same file I read from the ECM and flash it back, never had an issue until today, the .cal I read from the ECM isn't accepting OS patches (to disable VATS) so I can't start the engine. That's why I'm trying to flash a different cal, to be able to apply the VATS patch.
