AEM Problems with everything AEM

Good idea, ryan1. I sometimes forget but there are at least two types of serial cables. You need to use a standard 'straight through' serial cable, not a 'null modem' cable. Most null modem cables I've seen have the letters 'NM' stamped somewhere on the connector.

Nothing worked as usual. Spoke with AEM and nobody has any idea. Both ECUs were confirmed working. All wiring is fine at the harness, double and triple checked. Going to give it another run through and then give up and go with something else.

It honestly sounds like it could be something on your end and not a AEM issue. Do you know any one with a laptop with a native serial connector? That would tell you for sure if there is something else strange going on. It would connect for sure if everything is working. I have issues connecting once in a while using the USB adapter. I know people that have adapters that never connect and had to buy a different brand to get it to connect at all.

I am having a problem with my AEM as well. I am trying to download my map before sending the ECU in for a revision and it keeps telling me it cant connect and that its off line. The car and ecu both have power and will run on the ecu. I am using a Trendnet TU-S9 Serial to USB converter and have tried rebooting my computer. Suggestions?!
