13.7.2 Engine Fixed Speed Control (EFSC)
This feature is enabled in the ECU software for all IPU applications. The EFSC system can
be set On or Off, with a range of set speeds and choice of increment and decrement step
sizes.
This system needs electrical switches to be connected to three pins on the engine ECU. This
feature cannot be used in conjunction with two twin track control devices. Please contact
your JCB Power Systems Applications department for more information and advice.
