Depending on your application, you may have to drill one 3/4" hole in the K&N intake tube for the air temperature sensor. K&N provides step-by-step instructions with each kit, so we will mostly cover the installation through color images that illustrate key steps in the process.  Fuel Injection - ATV - Engineering </font></p> <font color="#FFFFFF"> <p>Fuel Injection - ATV Electronics Promoting the best of Industry, Technology and Manufacturing in the USA  The EFI atv is the same basic unit as the 2004 carbureted version with a few key changes, like the addition of injectors, sensors, fuel pump and the “ECU” black box to control it all. To check the drivability at altitude, we were allowed to test the EFI’s at 4500 ft and then from there we proceeded another 500 ft up into the Black Hills of South Dakota, for a total of almost 1 mile above sea level. One mile high means reduced air pressure and on the day we were there, it was near 100ºF. So the air was really thin. How would the 700 EFI "carburet"? We drove the EFI’s in very technical terrain, where precise throttle control was mandatory (unless you wanted to go on your head!). We could not detect any of the carbureted 700’s characteristic off idle burble, nor was there any sign of altitude induced richness. The fuel injection seems to adapt to the conditions correctly, reducing the amount of fuel injected into the combustion chamber. This made the 700 EFI atv easier to ride than the carbureted versions we had on hand for comparison. It looks like the EFI allows the motor to run the way it was designed to. Polaris claims up to 10 miles more range per tank at full throttle and 16 additional miles at more moderate throttle openings. This will somewhat address owner complaints of poor fuel mileage.  The next question would be what happens if the Bosh EFI fails. First off, the ECU will revert to "fail-safe" mode so you can get back home, so you won't be left out in the "toolies", however you will loose the ability to adapt to ambient conditions. There are two parts to the software of the ECU. The first part of the software controls how the engine runs by regulating the amount of fuel flow through the injectors by polling a series of sensors. The second part of the software consists of the diagnostics. The diagnostic software knows what the reading from the sensors should be and is constantly on the lookout for an anomaly. When the software detects something thats value is beyond a preset parameter, it first tries to correct the problem. However if the problem is outside of its on-board capabilities, it issues a trouble code. A laptop, running the Polaris proprietary software, is connected to the 700 via a special cable to the ECU access port, which is hidden behind a plug where the carbureted version has its choke cable. When hooked up properly and the software is running, the fault code history can be accessed so the dealer can see what has happened in the past with the EFI system. <br> </font> <table border="0"

diagram converted to electronic which will actually walk the service technician through the steps required to find and fix the problem, going so far as to provide the wiring diagram and pictures of the actual component and even where to put the test meter leads. The ECU contains "Flash" memory like the Bios of a computer. This allows a Polaris Dealer to re-flash a new "engine map" to correct a problem or to allow for performance modifications. Polaris has promised to have this technology available to its ATV dealer network before the 700 EFI Sportsman is released. And they hope the dealers will use the diagnostic software as just another tool available to them. </font> <p align="center"><font color="#FFFFFF"><A HREF='mailto:info@dobeckperformance.com'>info@dobeckperformance.com</A><BR> Registered Copyright© 1999 to 2007 Dobeck Performance Products <br> </font></p> <center> <font color="#FFFFFF"> <font size="3" face="Verdana, Arial, Helvetica, sans-serif">Thank you for visiting www.dobeckperformance.com, where we provide engine tuners<br> Motorcycle Fuel Injection Kits and Electronic Fuel Injection Systems.</font> </font><font color="#FFFFFF"> </font> </center> </ul></blockquote></center></BODY>
