QR25DE ECU/Wiring Diagram

[QR25DE]

Hey, does anyone have a QR25DE ECU/Wiring Diagram for Altimas/Sentras? In particular I'm looking for 2009 Altima Coupe ECU Wiring diagram. But whatever you have post it up. I'm looking for all the wire colors and what they are for so I can wire in an AEM FIC.

Thanks!

Is this the company you are purchasing the F/IC from?

Have you purchased it yet?

Plug & Play Fuel / Ignition Controller (F/IC)

Plug & Play piggyback Fuel and Ignition Controller (F/IC). This kit combines the power and drivability of the F/IC with a plug and play harness, start up calibration, and “quick start guide” for fast, easy installation and simplified tuning.

Plugs directly into the factory harness. No rewiring necessary. Includes start up calibrations. Enables MAF-clamping/ recalibration. Runs in conjunction with factory ECU. CAN-BUS not affected. Among the only piggyback systems which can decrease pulse-width, allowing larger aftermarket injectors while maintaining proper air/fuel ratios. 64kb of internal data logging.

Yea for the Scion TC, there is no plug and play for the Altima so I need the diagram or can spend more time tracing back the wires.

I just looked at the AEM Power website. For 2009 model years, they list applications for Acura, Chrysler, Dodge, Jeep, and Honda.

I saw nothing listed for Nissan vehicles.

Are you going to go commando and try to make it work on your Altima?

Will it even work on Nissans?

[QR25DE]

Yes it works on Nissans or I wouldn't be bothered with it in the first place.

Just need the diagram to wire it up. Anyone have it?

Edit: Nissan is looking for it for me (Dealership), i'll scan and post it if I get a hold of it.

Can anyone confirm if the 09 4dr and the 09 2dr use the same ECU?

Found this manual: http://www.boredmder.com/FSM/N...C.pdf

From another post of mine:

I checked with Courtesy Nissan, 800-527-1909

http://www.courtesyparts.com/kb_search_ ... _6253_6257

I found out that to cover Altima model years 2007, 2008, and 2009 both the 2.5 and the 3.5, there are a total of 11 different Electronic Control Modules listed in the Nissan part book. The ECM is also known as Control Unit-EFI.

The breakdown is as follows:

2.5 4 listed for CA emissions cars2.5 4 listed for 49 State emissions3.5 3 listed for all 50 state emissions

Something interesting is that on the 3.5, they list a separate ECM for the SE CVT, the SL CVT, and the MT .

No difference on 2 or 4 door.

Throck thanks! Do you know if the wiring on the 2008/2009 model year is the same for all ECMs though? Or is the wiring different between them?

Tomorrow I'm going to take a look to see if any of the wires match what guides I have.
