Nah your ok matt, some suppliers are saying they dont need the controller
and some are saying even though they dont need it they can be used with it if you wish.

So conflicting info, once they arrive I'll test them out and let people know what the go is.

Sorry for the hijack Callum, just thought Id post up the differences.

Most gauges aren't accurate anyway as tested by a company over east with quite a few well known gauges, the only one to be exact was an A'PEXi 10,000 rpm Tacho.

Which can be seen here, although no Defi or Defi knock offs were tested it gives you an insight to readings accuracy:

So will be interesting to try test these against some real Defi's.
