Overview
EMIT engine control products (AFRC, Ignition, and speed controller) can be used on Waukesha VHP engines of various types. These kits can replace the ESM or upgrade older engines. This page covers ordering, install, and operating information.
The engine control products and Brain (annunciator) can be used in any combination. Often all will be installed (Ignition, AFR, Speed, and Brain), but some other combination of modules or even a single module can be used. The home page will show any combo of modules that are currently attached as a new tab.
Ordering Information
The sections below show what AFRC, Ignition, and governor kit would be selected for different applications, and the item numbers for spare parts.
AFRC
Note that the kit item number includes all items on that row except the module, which usually is already in the panel.

Throttle Actuator
| Servo Connector Pin | Harness Wire Color | Panel Destination |
|---|---|---|
| A | White | Batt + |
| B | Shield or Yellow* | Ground |
| C | Green | Speed Pin 26 "Anlg out" |
| H | Black | Batt - |
| I | Red | Speed Pin 20 "TB Pos 1" |
| J | Shield* | Ground |
*Early harnesses had shield route to B, while later harnesses have shield route to J with Yellow routing to B. In either case, shield should always go to ground and yellow (if present) will go to ground.
Note that a 182 ohm resistor should be installed between pin 20 and 23 of the speed/governor module.
Hall Sensor
The diagram below shows the hall sensor wiring. Note that pin 14 supplies 12v to the red wire, and the white wire will have a weak pullup to 5v supplied by pin 24.
Flywheel MPU
The Flywheel MPU wiring diagram is shown below.
