It is scam,, no way to download the calibration files I tried for houres no way.. Wrote to their teches also no answer!! finally I reprogrammed by my dvd
I have flashed many Toyotas with the Maxiflash. I use the toyots techstream software and it shows if an update is available. I click yes. then it open s the TIS webpage to download the CUW. then just run the CUW. P. S.: CUW is Calibration Update Wizard.
