Default Is there a fuse inside AEM Ems?

I towed my car home with no sparks. I diagnosed the ground - crank sensor - cam sensor - fuse - relays ---THEY ARE ALL GOOD.
I put my HONDA STOCK ECU, THE CAR STARTED!!

IS there a fuse inside the AEM BOX THAT BLEW OR I HAVE TO SEND THE ECU?

Update: I put the stock s2000 ecu and fired up!
Then I put the AEM back --- fired up !! what dahhhh!!
What's going on? the whole day there is no spark all of a sudden after I primed with the stock ECU it works..
Can someone tell me what's going on with this AEM? I'm sure there was a bug in 1052 that they are
not telling us.

I just got an used AEM 1052 and its keeping the car going but not holding a connection to the AEMPro. I work in Technology and repairs and trouble shooting is part of the job.

1. Did you receed(take out the cables and put back in) the cables on AEM. Then start car.
Or
2. Did you go straight to the OEM ECU once the ECU wires were taken out?

If 1 did you lose power to the car at all?

If 2 could be loss cable

Yes I did go straight to the OEM ECU connection and started quick.
I removed the OEM quickly after the 10 seconds idle and put the AEM back -- AEM started!

Hopefully a bad connection, but I have not touch the ecu connection for a year.

I'm actually thinking of keeping my OEM ECU in place just in case this happens to me. I ended up stuck on the side when trying to put the basemap on. I ended up putting the wrong one on and keeping the factory one in place kept me from getting towed. I have a the AEM basemap but looking to see if anyone can send me a tuned one. I have a post in this section if anyone can help out.

I use to do hardware repair and at times just receeding the ram, HD, and battery would fix non booting laptops.

Yeah--- I plan to bring my stock ECU from now on.
I have a tuned one using supercharger at 10 psi....give me your email and I will send it to you.
I have no problem sending map -- someone helped me too and got a map so, I will do the same. Nothing sacred and secret on the map.
