I've never done a proxi alignment so can't help much - looks easy enough to do with MES though. What I'd like to know is how prone to catastrophy is the procedure? I've read that, under certain circumstances it's possible for the ECU to be wiped and if the relearn/recognition of ecus fails during the procedure then you're absolutely stuffed. For this reason it seems it's advisable to always make a backup of the system before starting to do the realignment. If it all goes pear shaped you can then use that to reinstate your starting point. Is this true and if so exactly how is it accomplished?
