Hi I read the tune off my Holden Commodore SV8 2003 LS1 with my new MPVI2 fine, made some mods to the timing tables and torque convert lockup settings and went to write (Cal only) the modified tune back into the car. On my first attempt it said unlicensed file (I had already licensed the file). On my second attempt it started going through some programming steps. It stopped on Erase, stayed there for a while and then stopped communicating. The car now won't start I have tried many times to write the cal but it just says Failed Controller Unlocker: Timed Out
1. I thought writing Cal only was low risk and a routine task for your software/hardware.
2. How can I get my car going again ASAP - it is my daily car and needed for transport to work etc.
I have tried the following:
1. Switch key off and on again
2. Remove battery terminal for a few minutes, reconnect and retry programming
3. Switching to a different computer.
