We recently upgraded an engine from a 5790GL to a 5794LT complete with ESM-1. There are several distinct benefits to upgrading your engines with the newest technology, but our customers often aren’t aware that there are many options as to how far you take it. In addition to a standard overhaul in which all power cylinder components would be changed, Waukesha supplies kits that are installed to complete each stage of the conversion, so you can choose to what extent you want to change the engine. When installing the ESM, quite a lot will change. This article will walk you through some of the added benefits the ESM will provide in an engine upgrade.
ESM vs CEC Box
The ESM is an improvement over the CEC box in that the engine can now monitor engine load, temps and knock detection with a fuel gas analysis to determine optimal timing for the engine. The 5790 GL is not a simple conversion in the fact that you are eliminating a lot of harnesses and an extra fuel manifold that is no longer needed as well as some versa valve sequencing for turning fuels on at the right time for start-up. In the end, the ESM ends up making the block less clustered and easier to maintain and service. It also gets rid of a lot of tubing lines needing to run back to the panel to monitor pressures and temps. Lastly, transmitters installed directly into the engine and hooked into the ESM can be brought back to the panel through the customer interface harnesses.
