Power Commander 6 Yamaha XT-660R/X 2004-2006

Avaiable for the Power Commander V is the add-on Auto Tune module which allows for live, closed loop EFI tuning. Based closely on Dynojet's new Wideband Commander 2 it features a OEM quality Bosch Wideband O2 sensor. The Auto tune module allows users set a demanded air/fuel ratio in the Power Commander V software and the Auto tune will make adjustments in real time. When enabled there is an AFR table with the same 250 RPM increment resolution as the fuel table. The Auto tune can be configured for minimum run time before live sample as well as maximum +/- fuel adjustments in relation to the base map. The Auto Tune kit can also use the Dynojet map switch or any open/closed switch which allows the user to switch between live tuning to the parameters set thru the PC V software or the base map in the PC V unit. You can leave the map switch in "live" mode, or if you want to write the fuel map you can connect to the PC V software, retrieve the fuel trims and either write them to the map or clear them. We have also compared several Auto Tune derived maps to dyno tuned maps and the results were impressive. A very important requirement for building a good tune is to have a close base map to start out with, as the Auto Tune writes its fuel trims off the base PC V map. The Auto Tune module does require some basic wiring from the sensor harness into the modules. The Auto Tune module is a very good choice for those with a unique mods, where a dyno is not available, or for those looking for the ability to tune in real time. The ultimate combination we recommend is combining a full dyno tune session with the Auto tune. We build the map for the best combination of performance and efficiency, and then implement the AFR's we developed into the Auto Tune AFR table. This strategy will provide the best performance under all conditions. · Live fuel mixture setting while driving · Basic setting already programmed · to be used as a mobile setting module · incl. OEM quality Bosch Wideband O2 sensor · can be used only with the Power Commander V · NOT FOR USE WITH 2-CYLINDER BIKES (e.g. XT1200Z)!!!!  

DNA High Flow air filter for all Yamaha XT-660R and XT660X from 2004 onwards. The exchange airfilters simply replace the standard airfilter. The airfilter box doesn't have to be modified. Up to 40% more air flow in comparision to the standard paper filter. The filter only has to be cleaned when it has a 2-3mm thick layer of dirt. Cleaning only each approx. 80.000km. No more filter change - the oil impregnated cotton fabric of the filter ensures a maintenance-free life. The filter merely hast to be cleaned and oiled overy now and then. The DNA Exchange airfilter improves the performance: because of the better air flow the mixture volume is build up and provided more quickly. The engine reacts more spontaneously when accelerating. It also converts the faster filling of the cylinder into a better acceleration. In addition, this high flow filter is often able to correct the losses which are caused by complicated ways of air supply and airfilter boxes which often constitute a compromise between space proportion and effectivity. The High Performance! The High Performance of the DNA air filter is a must for all of our designs and our R&D team uses up to date Hi Tec equipment to achieve the best performance. Our R&D department is equipped with the latest Dynojet motorcycle & automotive dyno's and sophisticated air flow measuring equipment. Every single filter is tested and checked that it meets the High Performance standards that DNA has established. As a final result the customer receives the best performance air filter money can buy!
