I am trying to setup rev burner with a TypeR rev counter. The rev counter has been tested on a actual vehicle and is working fine.
I have put the White & Red wires from the rev counter on the + of Rev Burner and the black wire from the rev counter on the - of rev burner. The green wire (going to coil on actual vehicle) from the rev counter was added to S1 on the rev burner.
12v 1A Power supply was plugged into the power socket on rev burner and usb plugged in.
Sim Dash show that the rev burner is detected by there is no lights on the rev counter and pressing the test button on the software result in nothing.
OK, dismantle everything and connect another power supply (Regulated 13.8v 3A) red directly to the rev counter (White & Red wire) and the black to the - on the rev burner and the black wire of the rev counter based on schema below:

Playing Dirt 3 and my GI-Pro works 100%, but still nothing on the rev counter.

What am I doing wrong, or is the rev burner faulty out the box?
