What are you using to connect? I have had good luck so far with my radioshack usb to serial adapter. But you have to make sure that you have serial selected as a connection port.
Other wise make sure you have power and ground at the correct pins.

Should clarify too that the car has had the AEM for 2-3 years, so he has connected to it before.
As for what he's using to connect, look at the first post. "tried two different laptops, three different installs of pro, serial and usb ports..." aka he has a laptop with a serial port, as well as a usb to serial adaptor that has worked before.
We checked the PROM chip as well, but it seemed snug still. If all else fails, I do have a burner to reburn the firmware, but then we are SOL with ZERO maps for the car.

Just call AEM and see what they have to say. I have never had that error. Sounds like it might be a hardware issue.I found a bunch of instances of not being able to connect on the forums and most of them were solved with the EPROM chip not being seated well enough.
Mitch said something about you having to downgrade the firmware to get it to work before? It is on old firmware v1.11, but came with v1.03. I downloaded the newest version of AEMPro, and will try to give that a shot today. Then see what AEM has to say.

How are you going to downgrade the firmware if you can't connect via serial?
-
Sucks, what happened that started this? You just connected and got the error out of the blue? I was upgrading the firmware a few years ago with a USB adapter that went fubar and wasted the chip. AEM is good about sending out replacement chips quickly.

I am pretty sure if it is running at all, there is still a cal on it. Not sure on the connectivity issue. Good luck, Mitch.Right, but if we have to hardflash the chip without being able to connect, won't that delete the cal on the PROM?

i would bet the last time i had it connected was two years minimum. if that counts as out of the blue then yup ha.
not only am i worried about having to buy another one but i dont have a backup cal. yea. weak. means i cant even start it with a new one.
edit/ you asshats wrote all that before i finished two sentences?

It's something in the cal conversion I think. Just don't update the firmware until you're on the dyno ready to tune?
