Lingenfelter NCC-002 Nitrous Control Center Installation and Operating Instructions 29
3.1.9 NCC-002 Connected to the Pin on the ECM for EFILive Nitrous Operating System and
Fuel Control
This configuration allows the NCC-002 to activate the E85/Nitrous feature of the EFILive custom operating
system on E38 and E67 Electronic Control Modules (ECM). This allows the production ECM to control the
additional fuel needed for nitrous and to modify the ignition timing based on nitrous activation.
The +12 volt output from Relay 2 is connected to the ECM and the Relay 2 output is activated when nitrous is
activated, allowing you to target a different air-fuel ratio (AFR) and ignition timing when Relay 2 is commanded
ON. This can be used to provide the fuel for the primary stage of nitrous or for a secondary stage of nitrous.
When used as the fuel supply for the nitrous, this eliminates the need for a separate fuel supply system, fuel
solenoid(s), and fuel nozzle(s). It also eliminates problems of fuel distribution that can occur with plate-style fuel
supply systems in intake manifolds not normally designed to distribute fuel.
NOTE: The wire colors and pin positions in the following wiring diagram are for GM vehicles equipped
with E38/E67 ECM's ONLY. Identify the wires and pins positions of your vehicle's ECM and confirm
their individual functions before beginning the modification below.
•
Locate and unlock the ECM connector 1 on both the E38 and E67 ECM's. Pull the lever away from the lock to
remove ECM connector 1 from the ECM.
•
Expose the wiring going into the connector by disengaging the two (2) tabs on either side of the connector.
•
Locate pin 5 on E38 ECM connector 1 (black) or pin 2 on E67 ECM connector 1 (blue). The location of pin 5
for the E38 ECM is shown by the connector end view in the following wiring diagram.
•
Using an electrical connector pin removal tool (or equivalent), push on the plug that seals the connector. It
should not take much pressure for the plug to fall out.
•
Using an electrical connector pin removal tool (or equivalent), remove the black terminal separator. This can
be done by gently prying on either end of the black terminal separator, the part of the connector that is
inserted into the ECM.
•
If the plug is still in the pin position, remove it using an electrical connector pin removal tool (or equivalent).
•
Using a crimping tool, crimp a terminal (PN: DK321288) to the end of the solid orange wire labeled "RELAY2
12V". This end of the wire will be inserted into the pin position on the connector.
•
Insert the crimped terminal into the back of the connector. The connector MUST be oriented the right way so
that the open part of the wire slides into a locking tang inside the connector.
•
NOTE: You should here a "click" when the wire terminal engages the locking tang. If no audible click is heard,
the locking tang is not fully engaged.
•
Re-install the black terminal separator onto the connector by lining the separator up to the correct terminals on
the connector and pressing down until fully engaged.
•
Re-engage the tab on both sides of the connector to re-install the wire enclosure on the back of the connector.
•
Plug the connector back into the ECM and push the lever towards the connector to engage the locking
mechanism.
•
Connect the other end of the solid orange wire labeled "RELAY2 12V" to the "Relay2 Out, +12V" terminal on
the NCC-002.
•
Program Relay2 Out based on Nitrous1 or Nitrous2 activation.
