Max Volt Catalyst Eliminator Computer

121-120 + Option(s)

Max Volt Catalyst Eliminator Computer

The Catalytic Eliminator Computer (CEC) is designed specifically for marine engine application testing. A team of marine electrical engineers created this easy to use testing tool to define failed secondary or post O2 sensors needed for replacement. There is no cutting or splicing of wires; everything is plug and play! Perfect for testing a replacement performance or racing only non-O2 based exhaust system with a header system to obtain peak engine performance data.

If your boat has fouled its post oxygen sensors and is no longer under the factory warranty, then you know what it costs to have new sensors installed and the trouble codes cleared. This unit will bypass post O2 sensors and solve a failed/plugged or no cat application.

Note:

Only works with the 4 pin plug switching style O2 sensors.
Will not work on the newer wide band O2 sensors with 6 pin plugs.
Works with Mercruiser applications ONLY.

WARNING! This module is not to be used on emissions regulated waterways. The intent of this module is to allow the running of a catalyzed marine engine without the catalytic converters installed and without triggering any ECU error codes. With the engine operating in this condition, the emissions control system will be rendered inoperative. For this reason, do not operate the vessel on emissions regulated waterways. This computer system is not legal for any purpose other than testing purposes and not for use on any state or federal waterway.

MSD has raised the bar and added an all-new UL listed marine ignition box to their lineup. The 6M-3L is a fully sealed unit with a single wiring connector makeing installation neat and easy.

Three rotary dials and an LED display simplfy setting the cylinder select, start retard and rev limiter. Plug-in rev limiter chips and hard to read dials are a thing of the past. For diagnostic purposes, the LED display can also be set to a live tach mode on V8’s and even display battery voltage with the turn of a knob.

The 6M-3L is a capacitive discharge ignition that multi-sparks from idle to 3,000 RPM providing a clean idle and quick throttle response. Above 3,000, capacitive discharge sparks will run clean through 12,000 RPM . Boasting more features and higher spark energy than its predecessor, the 6M-3L is the performance upgrade your boat needs!
