I'm going to need an ECU for a VE project and would like to get the Calum RT v2, but from what I've seen support is limited. If I'm going to spend that much money, I'd like to see that help is available if I need it. Maybe I should go with a piggy-back system instead.

What's your guy's experience been? Any problems?

I have a rt v2 for like 2 or 3 months and I still havn't been able to use it for activating the vvl *** there is very limited support and time frames of availability. :(
