AEM EMS Series-1/2 Repair

I’ve been offering AEM EMS Series 1 + 2 repair services since 2015.  AEM has stopped providing warranty services for the Series-1 EMS for a good while now and that was a big bummer for series 1 owners – until now!

All Series 1 + 2 EMS repair jobs will go through a complete visual inspection and full bench test procedure. The list below is what will be tested on the bench. Upon completion, a detailed summary report sheet will be provided and emailed to you.

Repair Fee: $225 flat rate per EMS – whether it passes bench testing or not. Fee includes return shipping costs (within the continental US).

  • Although we will attempt to make a back up of your calibration during bench testing, we HIGHLY RECOMMEND that you make a back up of your tune/calibration before sending in your EMS!
  • I cannot guarantee your EMS will be repaired upon failing bench testing and/or has some kind of unique issue outside of what repair services are listed above.  Though, most common EMS issues are repairable through bench testing and/or an EPROM reflash or complete EPROM replacement
  • You will be notified if your EMS does not pass any of the said tests before it’s sent back
  • We cannot upgrade a Series-1 EMS to a Series-2
