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 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 HP EFI Systems, it is always more cost-effective to buy Terminator X as a complete kit. But if you have a Terminaor X kit and need a new ECU 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.
