AEM Infinity 508 cannot connect to software

My Infinity 508 cannot connect to Infinity Tuner software. I tried updating firmeware and reconnecting the ECU but the Infinity Tuner software did not find the ECU. Sometimes the software seemed to find the ECU but then the software stopped responding. Pls advice what I should do.

Looking forward to your reply.

Regards,

Need more info. Are you using

Need more info. Are you using a PC? What operating system? USB 2.0 or 3.0 port? Have you tried using different ports?  Are you running InfinityTuner as administrator?  Have you always had comms issues?  Have you tried using a different computer?  Are you sure that the Infinity is actually turning on?  Do you hear the main relay click on and fuel pump prime?  Does your engine actually start and run?

Interesting. Well, there's a possibility that something is up with the hardware on the problematic one. So you've never been able to load the firmware or import a cal?

What version of InfinityTuner are you using? What's the serial number of this ECU? Have you tried using Flash Enable?

Seems strange that you'd be able to load firmware but not a cal. When you loaded the firmware, did it complete 2 of 2 steps? Have you tried reloading the firmware? Have you tried using Flash Enable yet?

When using Flash Enable, the

When using Flash Enable, the firmware update process is in manual mode and when in this mode, only the first of two firmware files can be loaded. After the first file has been loaded, power the ECU off, remove the FE jumper, turn ECU on and reload the firmware again without using FE. When not using FE, the firmware update process is in automatic mode and both files will be loaded.

I have encountered the same problem before with another Infinity serial no.7108-0199. Can I send unit to AEM for inspection? Or can I fix it by myself?

I'm sorry but I don't know

I'm sorry but I don't know how this ended up before. I don't know what problem there was therefore I can't say if you can fix it or not. If you sent in units before for inspection/repair, then get back in touch with Tech Support to send this unit in if you want.

Hi, 

Hi, 

I have the same issue as the original poster describes. Its a very old ecu, P/N 7108-0043. Unable to communicate with ecu. (My laptop is able to communicate with other cars I have here with infinity on, so its not a laptop, usb or lead issue)

Tried flash enable process, which allowed me to upload latest 96.3 universal firmware, but once I turn ignition off and remove the flash jumper, there is no further communication possible with ecu. I cannot then reconnect without the flash jumper and upload the firmware again.

Is this ecu likely to be running very early firmware that simply isnt compatible with the latest tuner sofware? If so should I return ecu to AEM for an update?

 

Many thanks,

Karl
