CRF250L: Fuel and Intake

Tried, true and tested the Power Commander continues to evolve with the Power Commander 6.  Developed to simplify the user experience, PC6 makes choosing and tuning a map easier for the end user.  All the same benefits you have relied on for over 20 years remain to keep you at the front of the pack. 

The Power Commander 6 fuel injection tuning device allows you to optimize your fuel and timing curve (where applicable) giving you the confidence to roam freely.  With fine tune adjustability and multiple inputs, the Power Commander 6 will keep your vehicle running at its full potential letting you concentrate on the journey ahead.

Featuring a plug-and-play setup, Power Commander 6 can be installed discreetly underneath your seat, cowl, dash or other location ensuring your ride looks as good as it runs. Removing the device reverts your vehicle completely back to stock.  With the ability to store and switch between two maps on-the-fly  (via the map switch accessory) and connect to various Power Commander accessories such as the Autotune, Quickshifter or POD-300, the Power Commander 6 gives you features and functions that provide you with the ultimate ride.

All PC6 models have an end-user adjustment of +/-15 in the FUEL table and +/- 8 in the timing table (if applicable). This adjustment is on top of the values that are in the BASE map loaded to the device. This BASE map can be any of the available maps from the Dynojet website, or those you may have received from a third party.

The EJK evolved out of the need to address the ever-increasing complexity of factory fuel injection. For the newcomer to the market or professionals wanting an easier method for tuning fuel injection, the EJK is a customizable solution for the rider that wants to take control of their tuning needs.

This unit is a piggy-back EFI controller because it does not replace the stock ECU, but rather monitors the signals to the injectors and makes fuel adjustments based on the mode settings. The GEN 3 has a push button interface allowing access up to 6 different modes to allow for quick fine tuning by the end user without needing a computer.

Key Features:

• No computer or dyno needed!
• Plug and play, simple to install, base settings preset
• Unique load based technology
• Full range tunability available
• Does NOT interfere with stock ECU operation
• Simple push button adjustment interface
• Water-resistant 
• 2-Year warranty
• Compact size - 2.2" H x 3.4" W x 0.5" D

Dyno and field tested, the Power Surge 6X will allow correction for humidity, temperature, air pressure, along with race fuels and motor modifications. The tuner adjusts in a matter of seconds in 6 zones, including an accelerator pump feature for more throttle snap response. The tuner can add or subtract fuel from the injection system. Conditions like rich or lean running, and stalling from flame-out at low revs can be corrected.

Driven Engine Block-off Plates will stop the annoying and possibly damaging backfires from occurring while allowing you to remove a few pounds in associated valves and hoses from your bike. On late model EFI bikes with O2 sensors, ESPECIALLY when using Dynojet's Power Commander 6 with the Autotune feature, the air injection system MUST be blocked as it will introduce additional oxygen into the system which will skew your O2 sensor's values and make it impossible to get a correct tune.
