Feed-back for the unit is going to be extremely hard, as it has only been on the market for about 2 weeks.
But from all the reports, info, etc, that i have read/discussed this is going to be a top unit and well worth the money. But remember, an ECU is only as good as the tunner
The bugs on my V4 have been fixed, by a simple upgrade to my mechanic's tunning software. My idle is steady, A/C is also steady, and it does not foul up plugs.
The V500 is miles better than the V4, and is said to equal or maybe better MOTEC, but only time will tell. On paper, it has the "goods", let's see what happens in practical applications.
