When asking for technical help at the very least let us know the version of firmware you are running.Cliff's Calibration (Mapping) Guide is a MUST READ: http://www.vemssupport.com/forum/index.php/topic,97.0.html
Can I share the 12v that goes to the relays turning the ECU on and off, or will the tacho wire from the ECU make the power relays turn off?
Ok thanks, is there a rule of thumb of what resistor to use? Or just try one? Like 330Ohm
Tried a 470ohm one, so going to go out and buy some lower value ones and give it ago.O I'm using pin 6 of the 36pin plug.Do I set the tach output to Inject channel 6 or 7? As I have read that pin being referred to both name.
