Overview

Holley Single-Channel EGT Controllers

Holley Single-Channel EGT controllers are designed for use with a K-type thermocouple using a "mini-K" connector. The module's accurate temperature measurement range is 32-2,282 degrees F (0-1250 C), with an accuracy of +/- 5 degrees F. The module is available in two versions: either CAN 1CH EGT, which is a plug-and-play installation for compatibility with Holley EFI products, such as HP and Dominator EFI systems; or Analog module, 1CH EGT with a "flying lead" with three wires exposed for power, ground, and signal for non-Holley EFI installations. Order the EGT controller suited to your application needs.

Plug-and-Play, 1CH EGT controller features:

* Supplied harness features two CAN connectors (one male, one female) that plug into the Holley main harness (or P/N: 558-412 kit Dominator only)
* LED: Green LED indicator on unit shows solid green color to signify device is operational; flashing LED alerts no thermocouple connected or it failed
* Note: before mounting, it is recommended you record the CAN ID Serial number from the sticker on bottom side of the unit for use during software setup
* Mounting: EGT module is designed to be installed with zip-tie or a pair of #6 or #8 screws
* Software setup
* Important note: Requires software and firmware Version 5 Build 31 or later

Analog module, 1CH EGT controller features:

* Wiring: harness is a "flying lead" with three wires exposed for power, ground, and signal (red wire: power 6.5 V-24.0 V; black wire: ground; and tan wire: Analog output)
* Outputs a 0-5 V and can be used with systems that have configurable 5 V inputs
* LED: Green LED indicator on unit shows solid green color to signify device is operational; flashing LED alerts thermocouple not connected or it failed
* EGT module is designed to be installed with zip-tie or a pair of #6 or #8 screws
* Analog setup: analog output scaling is accurate between 0.5 and 4.5 V and covers temperature range of a K-type thermocouple
