    Honda FMX CDI tuning

    Just found this on the internet:

    http://www.cdi-fmx.es/_equipo.html

    Any thoughts on this?
    All those extra horse power with only another CDI?

    unlikely, but not outside the realms of possibility. The FMX is detuned from the original Dommy after all. I know the cams are different, maybe the timing/advance is too.

    37hp from a 650 is pretty pathetic in the scheme of things, so there is obviously scope for tuning it somehow

    If it were just an inline resistor thing then i would be very suspicious, but it appears to be a complete CDI, so who knows.

    Anyone brave/rich/foolish enough to try it?

    The FMX is based on the NX. The NX '96 has a claimed 44HP (version without smog pump). Looking over the specs, I can't think of any particular reason for the FMX to be such a gran'ma. Likely less aggressive cams, smaller airbox and obstructive exhaust.

    Since dommies can gain 10%-15% performance with less restrictive filters, bigger jets and larger headers&exhausts without much of a hassle, I don't see why an FMX can't hit that kind of performance levels.

    >Anyone brave/rich/foolish enough to try it?

    That will be me. And very pleased.

    History of Bike
    Bought 07 bike at a two years old as standard except for remus exhausts.
    These were way too load for me.
    Bought baffles for them. Still loud but better.
    No difference in performance.
    Removed AIS system and very pleased that the backfiring was now completely gone. Well almost i can still make it happen.
    Fitted WP lowering kit and bought low seat. ( I'm a shorty).
    Had K&N jet kit fitted by PDQ. Very pleased.
    Before and after dynos were similar (38 and 40 bhp) but actual performance on the road was like night and day. Fuelling now really good throughout the revs.
    I've run like this for a while now and just fitted the the MQtech CDI and pickup.
    Fuelling still feels good throughout, but it really has loads more as the revs pick up. Higher speed overtakes are now good. You don't chug past as it tries to pick up speed. It just pulls really quickly.
    I've also seen a huge mpg increase with the cdi. 45 before 57mpg afterwards.
    I've no idea what the bhp is now but I bet they are not far wrong and the mpg is a bonus as i can get a extra trip to work in before filling up.
    Only thing left to do is get bigger headers and experiment with a different carb... but all in good time.

    Re: Honda FMX CDI tuning

    Hi thereˇ

    I have just bought an Ignitech programable
    CDI for my FMX 650 and I am driving myself mad looking for info on how
    to build up a good map. Did anybody get to a good one? Does anybody know how is the CDI-FMX map? I am specially
    interested in the max advance at WOT, because in certain places I have
    read that it should be smaller than in middle throttle but the default
    map provided by Ignitech is on the contrary.

    Thanks very much in advanceˇˇ

    Hi Mark,
    I bought it from a tcheck company named Ignitech, IgniTech. The model is the TCIP4, which is programable for single or multicylinder engines.
    The CDI from the dommies are prone to fail, it seems to be a problem of a bad contact on the board inside, people say it fails when the engine is hot. As far as I know it is difficukt to fix, Did you try to find one on ebay (I sold one a couple of months ago for 40€)?

    According to Ignitech's list on the TCIP4 it is prepared for multiplecylinder engines (2,3,4 and 6), not single cylinders.
    Isn't it better to use Ignitech's DC-CDI-P that is prepared for singlecylinder engine?
    Last time I looked my NX650 was a singlecylinder....

    My mistake, I forgot that there was a difference in ignition wheels and pick-up on Dommies and SLR/FMX.
    Forget about my reply.

    Hi Mikelduke.With regard to your CDI you are using the right Ignitech unit for a FMX,The dominator one is not the same !,Have the tried the map supplied by Ignitech on Honda_TCI.exe from the drop down list choose SLR650, its the same as fmx 650, I am looking for a map for a dominator Ignitech CDI unit if any one can help.Regards
