*If upgrading from WinTEC 4.9 or earlier, ensure that you update your firmware before beginning to tune with the new software, as unit may lock up if using new software with early firmware.  Also, make sure that after upgrading the software and firmware, you convert your files by resaving them before loading them onto the unit. You can tell if a file has been converted by its size. WinTEC 4.9 and earlier files are 10Kb, while WinTEC4.10 files are 12Kb.  If you don’t follow these instructions, you may end up having to send the unit back to Electromotive.

**It is important to note that if the unit is programmed using 4.10.– or newer software BEFORE the firmware has been upgraded, the unit may continue to work until the firmware is updated.  If it has been programmed with the new software before the firmware was upgraded, you must reload the 4.9.26 software and program the unit with an old format bin file. WinTEC 4.9 is available here  Then the new software can be reinstalled and the firmware can be updated.  If you have questions about whether the firmware falls into the older category, please email
