ok i have the dynatek cdi in my 650 efi and i want the same low end punch out of my 700 efi that my 650 has. has anyone used or heard of the two power chips on ebay for the 700 efi? one is from hyper which i have heard of before and the other is from genesisl. are they worth it? does it gain much? is one better then the other? and i know it won't gain 30 hp but it would be nice if it did. what i really want is to get rid of that initial dead spot when you crack it down.

not sure about them two chips,but i have the copperhead made by VDI(velocity devises inc.) and i notice a little more power. When you order a vdi,your asked a few questions about your bike like tire size, after market exhaust,ect... Only thing im running is 28" tires so Lyle programmed the copperhead for the tire size which it basically gave me back the power i had lost going to a larger tire. If i wanted to,i can program it to run better using maps off their website. It has 2 settings. 1 is stock settings and 2 overrides the reverse button,takes the lag out when you hammer down and i think it idles 100rpm higher. People say they can wheelie easily,but hey must be running the map which requires 91 octane gas and the m109 injector or something cuz mine will not wheelie. Ive also got a bumper and winch in front so that may be weighing me down along with the tires. If you want to know more about it check it out at velocitydevicesinc.com. I think ill be selling mine here shortly. Pm me if intrested.

 

thanks for the response, how much are you looking to get for this if you sell it?

 

they now sell for $500. im selling mine for $300. They are a little pricey but you can program them the way you want it to run. I never did anything to mine to try and get it to run the best. When ordered it came with the setting for 28" tires,thats it. For $50 you can get the interface to download new maps to run what you want,injectors,exhaust,ect... You will also need a $10 usb cable(double female ends,i think) thats all youll need. If you go to Nyrocatv.com, they talk highly of the copperhead and you can also see how much they sell for in the classifieds section. Although if you wanted the new ones,the generation 2 copperhead, they are made to use on multiple atv models and makes.
