The Terminator X-Max ECU is most commonly purchased as part of a complete kit for a specific application. But if you need to replace or upgrade just the ECU in your Terminator X EFI System, we offer the ECU by itself. This is the same ECU that comes in the Terminator X-Max MPFI and TBI kits, but without any of the harnesses. While this ECU works with the same harnesses that are available individually to build Holley's Dominator and HP EFI Systems, it is always more cost-effective to buy Terminator X as a complete kit. But if you have a Terminaor X-Max kit and need a new ECU (or want to upgrade your ECU from the Terminator X to the Terminator X-Max) then this is the ECU you need.

Would you like to receive your new replacement ECU with your current configuration already installed? We're glad to do that--at no cost! Just select "Pre-Program My ECU" and email us the configuration file from your current Terminator X ECU.
