Ezlynk, bitbox, and pcmflash do it.

You can't do an obd read on this ecu. You will need something like ktag or bflash to dump out the firmware.

Was wondering if anyone knew how to find the checksum ranges on a PHF file Ford 6.4 08 . . I'm modifying the speed limiter and need to correct the checksum. Any help would be appreciated or possibly point me in the right direction. I uploaded the calibration file(stripped phf).
