    C109R Surge

    I have had my 109 for about six months and I continue to have power surges when I am in 3rd and 4th gears running at a constant speed. I took it to the dealer but it came back still doing the surge. Anyone else having this issue? I figure it was probably something to do with the fuel injection but that is just my guess.

    Might help if you tell us of any AM goodies you have added. Pipes, processor, filter????

    Looks like it's time to install a "bully"!!!
    It eliminated my surging problems.

    Surging is indicative of a lean condition. I would think that Xantos is running a high flow filter and AM pipes without a processor. AFR is probably in the range of 16 or 17 and should be no higher than 14.7. So the dealer, being usually of little help, did not put 1 and 1 together.

    J.D. did you do filter and pipe mods before adding the Bully or were you having surging problems running stock??

    install a power commander or a fi2000r
    making it a little bit richer will get rid of that.

    The Bully is superior IMO.

    It came from the factory that way. I haven't done any mods to the intake or exhaust yet! I probably will be doing that this winter tho. That is what I like about the Bully. I can set it up for my situation and change it easily as I go with more mods.

    Hola all, new to the journal. Haven't had any problems with my 109 at all. Had it for about a month now. Graduated from the C50. The wife has that one now.

    Ive heard of that problem with the c50s. Its in the fuel injection system. Cure is a new fuel proccessor.

    I have not done anything to the exhaust; it is as it came from the factory.

    I installed the PCIII last week using the m109 stock map from power commander website. Got rid of the surging smoothed out acceleration and also have better pickup.
    Going to install a new exhaust and intake then i will take it to get it to the dyno.

    Thanks

    Does it only do it at a certain rpm range or at all? It is a fast surge or slow?
