32 Trigger Ring Update Available for Holley EFI TC-2

Attention Holley EFI TC-2 Users- 

A firmware update is now available to allow your TC-2 to use our new 32 tooth trigger ring.  This update is available online for older units, and is standard in all units purchased after 12-15-17.  Units marked with “32T Ready” on the back are compatible, as well as any manufactured after  Dec. 2017.  (NOT AVAILABLE FOR TC-1)



Units manufactured before Dec. 2017 will have to be returned to Davis Technologies for a hardware update ($25).  There is no charge for the update if purchasing a 32 tooth ring from Davis Technologies.
