-====== "Nitrous" Control Wiring ======
+====== ECMLink's Output Control Wiring (formerly known as "Nitrous" Controls) ======
-DSMLink nitrous controls provide a means of defining parameters that activate the fuel pressure regulator solenoid output on the ECU.  This output is a switch 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 damage to the ECU.
+ECMLink's output controls provide a means of defining parameters that activate any one of a few solenoid outputs on the ECU.
-Also, nitrous controls are by no means used solely for controlling nitrous kits.  That was the original intention, but our users have been far more clever in how they use this feature in DSMLink.  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 the FPR solenoid output of the ECU to drive a larger solenoid through a relay.  The rest is going to be up to you and your particular situation.

-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.

+For the fuel pressure solenoid output, you'll want pin 57 (white wire) on a 1G ECU and pin 3 (blue with red stripe) on a 2G ECU.
+For the EGR solenoid output, you'll want pin 53 (black with yellow stripe) on a 1G ECU and pin 6 (light green with red stripe) 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.

 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.
