RB25 AEM Series 2 not getting power

[716RB]

Alright, so I have recently finished the wiring needed to run my AEM S2 but I am not getting power to the ecu. With the stock ecu plugged in I get switched 12v as I should to pins 49 and 59 and the fuel pump primes etc etc. When the AEM is plugged in, no relays click and there is no 12v power to the pins previously mentioned. Does anyone know why this would be happening? I am trying to load the basemap file to the ecu but cannot communicate with it unless it gets power. I have tested the ecu plug and I am getting power and ground everywhere else I should be. My thought is that there is no basemap file on the ecu, therefore it has nothing to switch the relay thru pin 16 and supply power to the ecu, can anyone confirm this or provide any other insight? It is the plug and play series 2 AEM for the rb25.

Assuming you have an ignition signal going to pin45 and battery supply to pin58 try disconnecting the wire coming out ecu pin16 and ground it going to the relay to supply the aem ecu with power and see if it activates the pump relay or not. That should give you an idea if there is an issue with the ecu

Built a bench harness to test the ecu. It powers up just fine and I was able to communicate with it and load the rb25 base file. Plugging the AEM back into the car i get power from the ignition switch to pin 45 and I tested pin 16 and I get switched ground as I should to control the eccs relay, but I get no power from the relay. Stock ecu switched the relay and gets power but AEM won't. I double checked all continuity of the relay and it is wired properly. Anyone understand why, even with switched ground properly functioning from the ecu, the AEM would not get power but the stock ecu would?

What do you mean by the AEM is not getting power? If you send power to 49 and 59 without the relay is the AEM ecu coming on?

[neostraight6]

Is it the original Nissan relay?

[neostraight6]

Original Nissan eccs relays if it is used can have burnt contacts so if the aem ecu has a higher current draw than the original ecu it would not come on, so try a new relay.

[neostraight6]

You did not say if you tried bridging the relay supplying 49+59 to see if the aem ecu can on in the car

[neostraight6]

Sorry should be came on not can on

[716RB]

I built a bench harness directly to a battery and it powered up just fine.

[neostraight6]

Try a battery supply to the relay supplying 49+59 on the load side

Fixed the wiring issue, the relay was so wrong I couldn't believe it even powered the stock ecu, and also confused how continuity even tested that it was correct. Regardless, I tried syncing timing corresponding to the marks on the crank pulley but it will not start. I switched from a hitachi to a Mitsubishi CAS and installed the AEM wheel. I cut and spliced it the same as the hitachi was wired which I have read and been told is the proper way to do it. How do I tell if I'm getting a signal? I was also told I have to set the AEM trigger pattern. Can someone please explain to me how to do this? Because my tuner pretty much wants nothing to do with my car unless it's running. Also, I have confirmed I am getting fuel and spark

[neostraight6]

Can you post pictures of what you did concerning the cas?

[716RB]

What should I take pictures of. I disassembled the CAS to install the AEM trigger disc. But my original CAS was a hitachi and wouldn't come apart easy and ended up breaking so I bought the Mitsubishi style rb25 CAS and put the trigger disc into that. So to use the new one it had a different connector that I was told is pinned the same so I simply cut off the old connector and spliced the new one on.

Post pics of the CAS plug and where you spliced in the wires from the Hitachi to the Mitsubishi plug

I'll grab some pics when I go to my shop next. I wired the sensor as follows
the pins on the sensor being numbered [1][2][3][4]
Pin 1 - 120 Degree Signal
Pin 2 - 0 Degree Signal
Pin 3 - 12V Power
Pin 4 - Ground

All tested and confirmed to be pinned correctly on the ECU.
