Harley Fuel Injection Buyer’s Guide to Dennis Kirk

Hi, I'm Bob LaRosa, welcome to "Fix My Hog." In the day and age of computers, everything is computerized controlled by computerized functions. There are no more carburetor Harley Davidson's available, everything is fuel injected, everything is computer controlled for fuel delivery. A stock motorcycle we need to remember, is set up from the factory to cover a broad range of driving styles and weather environment conditions, depending on altitude where you live, depending on the constant weather conditions or your aggressive or non-aggressive writing style. When it comes to installing some type of fuel management system, obviously a computerized system to control the signal goes to the motorcycles ECM, and controls fuel delivery from the ECM to the throttle body. I went to denniskirk.com. I entered in my model and year specific and come up with a broad range. Actually the range of available systems to control fuel delivery can almost be overwhelming. I wanna just take a moment, review a few of the options that are available through denniskirk.com, obviously it is year and model and rider usage specific. So like everything else we do in "Fix My Hog," I want you to do a little research. I don't want you to just type in denniskirk.com buy the first fuel management computer or control module that pops up on the screen. Do a little research, find what suits your mechanical ability to install. Find what's gonna suit your particular combination. Motorcycles in their stock configuration are marginally mapped. They do operate well, they run well, they'll run indefinitely in the stock configuration. But like most of us, I, myself, am not happy with out of the box or off the floor performance from my fuel injected Harley Davidson. I did find a few good computer control modules or computer fuel management systems, one of them being the Dynojet Power Vision which comes with an optional Autotune pack with wide band O2 sensors. Vance and Hines offers the FP three fuel pack, it interfaces directly into the HD LAN line, plugs in programs through an app through your smartphone. The nice part about the Vance and Hines unit, once you're done mapping the motorcycle, the unit can be removed from the motorcycle and the map remains in the ECM. Another very well built, very well utilized, fuel management system is the Cobra Fi2000. As you can see the PowrPro pack itself has no outside programming capabilities. It actually reads it's like a dynamometer under your back wheel all the time. It reads measurements from the ECM 80 times a second. So each and every time you roll on the throttle, it recalculates for the conditions that it's sensing. Again, you need to not only evaluate cost, how much you're willing to spend, you need to evaluate what combination of air cleaners, cubic inch displacement and exhaust systems you're using. Again, there's a broad range of maps available for each of these units, but you need to make sure that the particular map combination is gonna fit what's known as the hardware on your motorcycle. The exhaust, the air cleaner, the cubic inch displacement. And just a quick recap, pertaining to each and every one of these fuel management control modules I have on the table, the first one is the Dynojet Power Vision PV-1. It is build as the quickest and most powerful flash tuner on the market. It comes with a sophisticated yet easy to use three and a half inch, full color touch screen display. and mounts to the handlebars with an integrated amps four hole threaded inserts. It also mounts to most aftermarket accessory mounts, that feature the same style mounting system. Interface cable plugs directly into the bikes diagnostic connector, there is no computer required. Simply select the tune and follow the onscreen props to flash the bike. You can select up to six different tunes or maps that can be flashed to the bike as they're stored on the screen. One of the nice features of Dynojet Power Vision PV-1 is the stock calibration can also be saved as an editable copy and used as a starting point. It downloads and stores the stock calibration in case OEM restoration is ever needed. Dynojet pre-configured tunes or maps are preloaded on the unit, identifies the bike's information and automatically sort hundreds of applicable Dyno proven tunes. Fuel trims to optimize fuel curves are calculated and stored by Autotune basic and pro three. When it comes to Dynojets Autotune, this is a pack that coincides with the Power Vision unit itself. The Autotune unit as a standalone will not change or tune your vehicles air fuel ratio. It is not meant to run by itself, it is meant to enhance the Dynojet Power Vision tuneable pack. The Autotune unit itself comes with wide band O2 sensors, and the nice part about the Autotune ad-on, if your motorcycle's not built with O2 sensors, it does come with weldable bungs that you can put into any exhaust system. Utilize the wide band O2 sensors and get the full benefit of Dynojets tuning abilities for your fuel injected model. The Vanes and Hines FP3 fuel pack will revolutionize fuel management for all new Harley Davidson models, using the HD LAN system. You can connect wirelessly by Bluetooth to any iPhone. Fuel pack FP3 uses flash technology to recalibrate engine parameters and mapping for exhaust systems and other performance upgrade. Downloaded from the extensive, expansive library of calibrations develop exclusively by Vance and Hines. A nice benefit of the FP3 module when it's plugged in, live sensor data can be viewed through the smartphone to display speed, RPM, cylinder head temperature, voltage, gear selection and other vital information. The Vance and Hines fuel pack the FP3 is a nice, easy, plug and play system can be adjusted, can be used to optimize any of the maps available from Vance and Hines website. The Cobra Fi2000. It's also known as the Autotune PowerPro Tuner. This system utilizes no downloadable maps. What it does it actually takes in the information from the motorcycle while it's running and recalculate it 80 times a second. It's very typical to having a dynamometer beneath your back wheel all the time while you're riding. Every time you twist the throttle, ask for fuel, it's precisely monitored, metered, and directed to the engine in the most optimum performance available through the Cobra PowrPro Tuner. It has a new patented technology. It tunes to exactly what air fuel mixture is needed to create maximum power. It does not tune to a predetermined arbitrary map or tune what's known as an AFR. It reacts, verifies and adjust to all conditions and writing situations. It provides perfect fuel settings in any condition with any exhaust and any engine modification. no external adjustments are ever needed, no Dyno is needed, no additional components are needed. and it does not require wide band O2 sensors.
