ok i got my 35R tuned for race and pump..im on pump right now...i have the 1313U 1.11 version AEM...i plugged it all in with USB to the computer..and it says "FAILURE CONNECTING TO ECU" then i took it to a shop and it reads "ECU OFFLINE" so i DL the 1.19 version,and that didnt work(didnt think it would) so how do i get it to work?DL a 1.11 version and then hook the AEM directly to a computer?cus i heard the USB sucks....PLEASE HELP ME....i wanna run my race tune tonite for the last nite of the track here in hawaii....

 

Do you have the proper com port of the USB adapter selected in the AEM software?

 

which adapter are you using to communicate with the aem via usb? i believe the keyspan adapter is the only one that will work. changing over to V1.19 will change your tune, might want to go back to 1.11.
