Can I import HPTuners tunes or other tuning programs into EFILive?

Or Vice Versa?

From time to time I see people who post a tune asking for help and I would like to open it without buying that program.

TunerCat has no issues opening LT1Edit files natively, so do other programs have that capability?

I know you cant do HPT files, no idea about others.

EFILive will read plain *.bin files as used by old HPT software, and EFILive's own proprietary *.tun files. EFILive will not read any othe software's proprietary files.

Is the OS part of the .tun file like my .bin is on my LT1?

Yes, the entire contents of the controller is saved into the *.tun file. Plus EFILive saves a bunch of other information such as the modification history of the file.

When you perform a calibration-only reflash, only the calibration data from the *.tun file is written to the controller.

When you perform a full reflash, the entire *.tun file (minus the modification history) is written to the controller.

HPT guys say you can't read a PCM tuned by another tuner. Why is that? Seems a limitation in the reading of the flash, you should be able to read it as long as the flash memory locations are the same. I sure hope people aren't screwing with that.....

I think they mean if the tuner has locked it.

There are tuners that lock their tunes, for what they say are proprietary reasons. That's their choice, but I would not have my car tuned by one.
