Based out of Bowling Green, Kentucky, Holley Performance Products is well-established for its repertoire of go-fast equipment and expertise. Now, Holley is showing off its latest Terminator X EFI system, its new standalone engine management offered in support of Gen V LT engine swaps.
Holley currently offers support for the system when integrated with the 6.2L LT1 V8 engine, the same motor introduced under the hood of the seventh-generation Chevrolet Corvette Stingray. Holley also supports the L83 and L86 direct injection engines, with support for the LT4 currently in development.
The Holley Terminator X EFI works to delete things like torque modeling, engine nannies, and other things that make an LT engine swap more difficult on older vehicles. The system also makes engine modification much easier. The system can adjust things like the fuel pressure and cam position, as well as the usual fuel and spark tuning, plus pretty much anything else you’d expect from a standalone engine management system.
There is an auxiliary input/output adapter that provides additional inputs to monitor various engine sensors, plus more outputs for various accessories. The system also works with power adders, including boost and nitrous control. OEM injectors are supported with plug-and-play installation. The Terminator Max with drive-by-wire functionality works with the LS and LT drive-by-wire systems.
A Bosch wide-band O2 sensor is used for the Holley ECU, and theres a hand-held display that provides everything needed to get it up and running – no laptop required.
The readout looks at things like sensor data and the air/fuel ratio, while the digital dash looks at things like the pedal position, engine rpm, and other info. There’s integrated data logging as well.
Both the 4L80 and 4L60 transmissions are supported. The Holley Terminator X EFI is also compatible with Holley’s various dashes, handhelds, and peripheral products.
Pricing for the system starts at $1,999.95 and goes up to $2,499.95 with all the extras and doodads. For those looking to execute their own custom LT engine swap, this could be the perfect solution.
