I have been using my series 1

I have been using my series 1 for about 7 years now, and throughout those years I have encountered "ecu offline" problems many times and for about a dozen different reasons. The problem could be the ecu or it could be the computer or even the cable.

Does the car currently run on this ecu? If yes its probably the computers/cables fault. Also if the ecu is not priming the fuel pump it means its not powered on, I run into this problem every once in awhile, disconnecting the battery for a few seconds remedies this for me.

Confirm the ecu offline problem on another computer, I've had certain computers refuse to connect. Try different cables, I have had issues with both serial and usb adapters. Strangely enough I'm having more success currently with an adapter than a direct serial connection.

The worst case scenario is something is physically wrong with the ecu, sad to say but I dealt with this one too, I had mine rebuilt years ago.

when you say other aem, your

when you say other aem, your referring to another v1 box on the same car? or a newer model? or a different car entirely?

aem no longer supports the v1 box, so repairs can no longer happen

try another computer if you haven't already, I've found computers to be very touchy when connecting to v1 boxes, I have a whole stack of them that simply refuse to connect
