First find out what COM port the usb-> serial convertor is using (device manager will tell you this), then in the AEM software there will be some kind of setup / connection menu (I've not used AEM software so don't know where exactly) where you can choose the COM port to use when communicating with the ECU, usually a drop down box.

 

Hope this helps!

 

Cheers,

 

Brian.

The USB to Serial device should have come with a CD, if not you have the make and model so get the drivers off the net. Once thats installed correctly the device will be listed under ports in device manager.

 

Then tackle the connection to the AEM

That will be why then. I have no idea of the make / model

 

Would any software work?

Try the driver I posted then try AEM website.

 

Tried that but seems to just be an uninstaller.

Also looked on the website but couldnt seem to find anything.

 

App. the installer need to match the USB to serial perfectly for it to work.

Think i may be low on luck :( No supra for me at JAE :(:(:( Thanks for your quick response though guys

No you need to point whatever is prompting you for a driver to the file in that folder, or force it to use that driver by choosing the unkown device in the device manager then choose update driver and point it to the driver in that folder.

Jon,

 

The USB to serial isnt actually that reliable.. you need directly to plug into the serial from the ecu?

 

Is this viable?

 

I had no problem with this and couldnt get an immediate connection to the ecu
