AEM EMS Series-1/2 Services

You may have landed here via Google search results, by word of mouth, or AEM support has sent you this way – regardless, welcome!

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 some time now. They’ve recently stopped supporting Series-2 and more recently the Infinity series 3/5/7 – big bummer until now! 

All Series 1+2 EMS repair jobs will go through a complete visual inspection, full bench testing procedure, on top of the issue(s) an EMS is being sent in for. See the list below for what entails an EMS repair job. Upon completion, a diagnosis report will be emailed and then shipped back to you.

**New Service Coming Soon** Series-1 to Series-2 upgrade (Honda/Acura only).

Note: Repair services for EMS Series-4 are not available at this time.


Repair Fees

AEM EMS Series-1/2 Repair Fee: $250 per EMS.
(This is a non-returnable base fee regardless if the unit test passes with or without issues)
Mainboard replacement is available at an additional fee of $320

This fee applies to passing or not passing bench testing but includes any/all repairs mentioned in the list below. Includes return shipping fees for U.S. domestic customers. International shipping fees are not included and will need to be calculated.
