AEM Infinity Services


Infinity Series 3/5/7 “UNBRICKING”, Bench Testing, and hardware repair services.

AEM has now discontinued repair services for their Infinity 3/5/7 model line. We offer three services for the Infinity ECU: Comms reflash (unbricking), hardware validation (bench testing), and new updated hardware repair services.

Comms reflashing aka “unbricking” is a software procedure we perform that brings an Infinity back to life. “Bricking” is when the Infinity ECU becomes unresponsive/dead after the following occurs:

  • Loss of COMS when uploading/downloading/updating unit
  • Power cycling vehicle too soon during a software upload/download/update
  • Power cycling (vehicle on/off) surges

Hardware validation (bench testing) is the process of checking all vitals of the unit and finding out if something is failing internally. This does not include any internal repair work at all, strictly testing only.  

*New services as of mid January 2023*
We have now expanded Infinity hardware repair services to a handful more of more specific components an additional incremental costs. See the service repair list below.

Additional HARDWARE REPAIR rates:

  • USB port replacement for Comms or logging port – $150

** PLEASE NOTE: The Infinity’s compact design has components on both sides of its internal board, with one side being completely inaccessible. A bit of destruction is required to access this side in rare cases. If there is a small chance that damage initially tied to the resistors, injector, or coil drivers could be linked to a component on this inaccessible side, this will/can incur an additional $150 fee. We will let you know before proceeding if your Infinity falls into this situation.

  • Turnaround time starts on the day your AEM ECU arrives in our hands and if payment is received too.
  • If you have an upcoming race and need your ECU repaired in a shorter window of time than we offer – I’M SORRY, BUT WE CANNOT EXPEDITE YOUR REPAIR SERVICE.
  • ECU’s are repaired in the order they are received. Please plan a minimum of a 2-2.5 week window for repair work to be on the safe side for your race plans.

  • I cannot guarantee your INFINITY or EMS will be repaired upon failing bench testing and/or has some kind of unique issue outside of what repair services we offer above. Though, most common EMS issues are repairable through bench testing and/or an EPROM reflash or complete EPROM replacement
