I'm sure some have ran the cobra unit, but I can't think of any off the top of my head. Most normally run a Power commander or have the stock ecu remapped.yeah i do understand but there was alot more to it than that. he trashed my bike while it was there.have you ever heard of any one using the fuel processor?Just to let you know that all codes are erased as soon as you turn the key off. He might have known this; that's why he didn't do it.thanks to all u guys. im new at this im not sure if i answered every one . i did take it to a so called fi guy an i wasnt impressed he didnt even try to see if any codes come up before he put it on dyno an when he told me that i went an took it back in a nice way. he had a dyno an said its def. running rich an he said it shouldnt do that with just a full muzzy on it. has any one ever tried that cobra fi2000 fuel processor.
