I was on the computer from 3am till 7:30am today with Bart from HPI. He sent ma some files to try... An un-installer for the driver in TuneBox 4, and a pre release version of TB 5. Unfortunately it is still a no go. So they are shipping a new PRE tested cdi on Monday (its already Saturday late evening for them). The first kit arrived in 4 days so I expect Fri-Sat of this week. Have no worries that I will return with the results. I can email the new version of TuneBox to anyone who would like it. This version is Win64 compatible, and there is a driver uninstaller that comes along with. The issues they have had with programing up to now has been the third party drivers for the chip. They have asked the manufacturer of the chip for THEIR driver to distribute with all TB5 software. It's avail now. The files are renamed to .cxc instead of .exe so they can be emailed. You will have to rename them to .exe's for them to run.
I hope this thread helps someone Post or PM me as I have this thread set to email on replies. Keep scootin' Z
