-====== ECMLink's Output Control Wiring (formerly known as "Nitrous" Controls) ======
-ECMLink's output controls provide a means of defining parameters that activate any one of a few solenoid outputs on the ECU.
-These outputs are all switches to ground.  That is to say when active, that ECU pin will be connected to ground.  When not active, it floats.
-But that ground connection is *not* sufficient to directly drive a high pressure solenoid.  You must use a relay and, preferably, a master arm switch between the ECU and the solenoids being driven if you're using large solenoids.  Trying to drive the solenoid(s) directly from the ECU **will** result in [[driver01|damage to the drivers]] inside the ECU.
-ECMLink's output controls can be used for a variety of things.  Our users have been far more clever in how they use this feature than we ever imagined.  They have used it to control water injection, methanol, [[UseNitrousControlsForDejonToolBOVMod|blow off valve bypass]], and probably a few other things we're not even aware of.  So this page is going to describe the general approach to using solenoid outputs of the ECU to drive a larger solenoid through a relay.  The rest is going to be up to you and your particular situation.
-Details on the internal functionality of ECMLink's output controls can be found on the [[NitrousControlDetails|nitrous control details]] page.
-====== Details ======
-First, let's get the ECU pins out of the way.  You can get a lot more information on the [[ECUWiringInformation|ECU wiring information]] page, including pin location and wire colors as well.  You'll want pin 57 on a 1G ECU and pin 3 on a 2G ECU.
-You'll probably use a standard ISO (Bosch) automotive relay.  If so, here's the function diagram for this type of relay.

-The following lists out the basic usage scenario of this relay.
-  * Run the ECU output to pin 86 on the relay.
-  * Run switched power (master switch output) to pin 85 and pin 30 on the relay.
-  * Run pin 87 to the solenoid and/or secondary relay you want to control
-That's about it.  Just as an illustration, here's a diagram one of our users put together when he wired up an NX nitrous kit to his 2G.
