This is the email i just received from aem. c

Found the EMS to have a burned coms circuit. Fixed coms circuit and fully tested the EMS. Found the EMS to be fully functional. All inj, coils, sensors, RPM readings, coms, IDLE circuit, UEGO circuit and stat sync are fully functional. Could not save customers cal. loaded base cal. Will ship unit 2 day express.

 

The maps I'm sending you are very basic intake and turbo back exhaust. I'm sending 4.

I had 3 maps and a working map to test things out.

The first map is from Utah with high elevation

The second two are AZ with normal elevation

The last one is a map I used to test different things out on.

 

Even with a cut harness this will work?
I know the basics of 5V sensors. I just figured with the cut harness he might be missing one.

 

Well if something was shorted in the harness, then it can cause all kinds of problems. However whenever I have seen connection issues, I always recommend you unhook everything except power, and try to connect to the ecu. Just some basic debugging.

I am in the process of stripping my harness as we speak, and I had comms issues also, I had just unhook all 5v sensors and was able to connect. This has happened to me a few times. Most of the time it is my TPS out of range, reading below 0.00%. This happens when I remove the TPS sensor and just guess when I put it back on.


But it looks like it was a legit board issues, and AEM got it all sorted out.

 

now i need to find out why that happened.

 

Did you receive the ems back yet? Just wondering if you got a chance to load the calibration I sent over and finally got to drive it
