M400 Plug-In ECU Kit: Snowmobile - Obsolete

OBSOLETE: M400m is no longer for sale

MoTeC Snowmobile Plug-In ECUs are fully programmable, direct replacements for factory ECUs on a select number of popular snowmobile models, based around the M400 Marine ECU. 

Complete with a wiring loom and mounting brackets, Snowmobile Plug-Ins are convenient and cost effective to install because they eliminate the need to rewire the sled. They simply plug into the factory wiring harness using the original sensors and fuel system.


Currently there are Plug-In solutions available for the following sleds:



Apex 2006-10, RTX, RTX ER, GT, ER, LTX, LTX GT and MTX


2009-Current, MXZ, MXZ-X, Renagade, Renagade X, GSX

Please supply all snowmobile details to your dealer, who will be able to order the right model Snowmobile Plug-In ECU for your sled.
