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.

*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.
