Need more info. Those codes don't mean anything since you are now on the EMS.
Here is some more information that I'm aware you need.
I've never used an EMS. I don't have the software for the EMS. I have zero experience with the EMS. (I know I will have to do some searching for software, do some reading and learning.)
The Stage 3 car is a completely different car.
(I have 2 SRT-4's.)
Here is a link to the car I'm speaking of:
Basically, this is a 2005 ACR that I bought. The AEM EMS system has been in this particular car for a long time, it should be fully configured and ready to go. Other than removing the engine from this car, making the changes I wanted to make and dropping the motor back in, nothing has been changed electronically with this car.
I've checked and double checked, and all the sensors on all the wiring harnesses are definitely properly secured. Nothing is not hooked up.
IMPORTANT HISTORY. And perhaps this is _the_ problem. When I wanted to buy this car, I phoned the owner and asked him to get me the mileage. He phoned me back a few minutes later saying he hooked the battery up, but the car really really didn't like it, so he unhooked it. (I don't know what exactly happened)
I told him to not continue messing with it, that I would come over. So I went over, I hooked up the one connector by the brake/clutch fluid and then hooked up the battery. Then I was able to read the odo reading. Then it was unhooked and the battery has not been hooked up for the last 4 months while I've tried to find time to put the car back together.
When I originally went to put the key in after I was finished with the car, it said a fuse was blown. I actually found one fuse, the FP/ASD 20A fuse. I replaced it. At this time, when the door was opened, it would NOT say so and would NOT display odo reading until the key was in and turned. Also, the gauges would do a strange "sweep" Going from 0 to wrapped fully, then settling back down to nothing in apparent stages. The car still said F U S E so I double checked and there was another 20A fuse blown. I replaced that fuse, which was Radio INT/LMP 20A fuse. At this time I also fully checked the wiring. I did find that the downpipe O2 sensor connector was not fully seated. So that was rectified at that time. As far as the fuses go, I don't believe that I blew these fuses, I think they were already blown. Since I have replaced them, they have not blown again when battery is hooked up or when the key is put in the ignition.
I'm now wondering if it is possible if he hooked the battery up backwards when I requested the mileage from him. And that's why it "didn't like it". If I'm thinking right, this might have then fried the alternator voltage regulator? Is that possible? I can't imagine he'd do that, but I guess anything is possible.
More details. The battery reads 12.65 volts. (So maybe a touch low) All the interior lights now work properly. So when door is open, it reads that and the odo displays. The lights work. The fan turns on, the windows go up and down, the headlights work, scan gauge powers up, the AEM gauges power on, etc. The gauges no longer do a sweep.
The connections to the EMS are seemingly OK. The third connection from the top as I view it from above looks like the clip is broken, and that connector doesn't seat properly. But it looks to me like it is currently all the way down. I can see they've tried wrapping electrical tape around it in the past to hold it in place.
Any of this helpful?
If there is something specific you need to know, now that you know all this, I can provide further details.
Meanwhile, I think I will remove this alternator and see if I can get it tested. My two primary suspects are alternator and a fried EMS unit. But since I'm not an electrical expert, I don't even know if the alternator regulates voltage in this car while it is not running. But I am assuming it does.
