<< Simple my Oriental friend
ECUTEK is a reflash of the std ECU with new s****y perameters but can only contain 1 map to read from. GEMS on the other hand can contain 2 maps and the switch on the dash interchanges between the "Road" map and the "Stage" map. So both have thier pluses and minuses
When i say map, i mean the reference table the ECU looks at to determine ign timing and injector timing
Will discuss further over Cheesecake on Sat night.
