    I'm definately no expert, but I recently had this done.

    Basically it sets the ignition timing to fire 2 degrees before the factory setting. In the FX35 the factory setting is as shown on the top table as 15BTDC (Before Top Dead Centre). This means that the spark will happen when the piston is 15 degrees before it hit the very top of it's stroke in the cylinder. If you advance your timming 2 degrees, which is in factory specs so it wont void your warranty, then the spark happends 2 degrees sooner. This will mean that the explosion in the chamber will have that much more time to burn everything up that was put in there (gas) creating more power. I can vouch for the effectiveness of this mod. It added pep and torque/hp.

    It's a great mod for minimal costs. I think it cost me $30. All they have to do is plug it in and hit a couple buttons. I almost forgot to add, it's recomended that if you get this done, to use premium 91 or higher gas to avoid chances of detonation. (An explosion in the chamber before the spark happeds) since higher octain gas burns at a higher temp.

    Go for it!

    Yah, the dealership should be able to do it for you.

    Just tell them you would like to advance the timing from 15BTDC to 17BTDC. If possible speak with the tech who will be working on your car, not the counter girl/guy. It shouldnt take more than 30 min or so.

    Enjoy!

    Better yet, get a proper tune & leave the base timing alone.

    No Need. Tune only.
    Timing is most likely retarding back to baseline when you punch it.

    My opinion is No
    When TS tunes you, using their "Technos Ecu Tuning" You get a reflash that would include all new Fuel & Ignition Timing Re-maps custom to you car, it's mods & the fuel you put in it.
    That is a way better route than a blind +2. Now, I had the +2 done before tuning, & I'm not sure if it's still there, but acc. to Tadashi, a true Ecu reset will in fact erase the +2 mod & bring it back to stock setting. No One's proven this yet over here, but Tadash is sure of it. Either way, if you get it done, all good & leave it in . . before the tune, but if you dont, no bigee, just properly tune your ride for optimum performance.

    But this is still a good option for those who are not ready for that mod yet,
    and for minimal costs.

    More power at low $$$$ makes Keemo a happy driver.:p
