FITTING

Fuel Optimiser Fitting

Take off the left rad panel and there is also a tool box under there that can be removed to make things easier. Follow the cable back from the lambda sensor in the header pipe until you see the multi-plug connector. Then simply disconnect the multi-plug, fit the Fuel Optimiser into the cable from the lambda sensor and plug the other into the main loom. Be careful not to force the multi-plug connection and bend the fragile connector pins. Secure the cable from heat/sharp edges with ties and refit body panels in reverse order.

 

NOTE: Please take care when fitting this upgrade, the wiring pin connectons are small and easily damaged so ensure they are correctly aligned before making the connection and DO NOT BEND or clamp the link wire.

The engine 'Service' warning lamp maybe illuminated when starting the bike for the first few times. This will extinguish following a few rides once the ECU has automatically recalibrated.

    701 fuel dongle

    The crt fuel optimiser, for the 690/700/701, gets rid of the throttle jerkiness. Fast delivery, easy to fit, and a much smoother engine. I covered mine in heat resistant electrical tape. The engine management light stays lit for about 100 miles before going out permanently.

    Doesn’t add to fuel consumption as you are able to stay in a higher gear without having to keep changing down or feathering the clutch. A must have upgrade to my euro 5 701 enduro.

    Thanks for the review Patrick. Over 600 of these have been sold over the last few years and as you point out the improvements on closed loop fuelling are clear and enhance the riding experience. Smoother running, improved throttle response and an added bonus is cooler running. Regards Dave CRT

    Essentially this appears to work, more so once warmed up. As from cold the bike appears to struggle a little as if close to stalling. However once warm the richer fueling see.s to suit tge leo vince exhaust. I didn't run tge bike without the dongle and just tge exhaust so can comment on staged changes. The smell suggests a rich mixture and the auto blipper is defined.

    With over 800 Fuel Optimiser sold world-wide it's a cheap first mod to the lean running issues. Some bike's ECUs recalibrate within a few minutes of fitting, others can take longer for the improvements to be noticed. It's a suitable upgrade for any bike, standard or with aftermarket parts fitted. It only increases fuelling up to a maximum of +5% depending on rpm, temperature, throttle position or even which gear the bike is in. Also important is that if a dealer warranty visit is needed this Optimiser can be quickly removed and untraceable.
