Wondering the same. I have this CTEK charger

Unsure if it'll work... I assume put it in car mode? With my previous car the dealer was using theirs in motorcycle mode. Used it over a 3 week long vacation in car mode and did not blow up my garage :P
Tangent, if you're in the LA area, I'm in Glendale and am gonna flash my car as soon as the OBD cables arrive. If you need a garage/charger feel free to stop by. PM me.
I guess I'll try with my charger in my car first ;-)
