    Remove catalyst

    I'm looking to install an airflow diffuser in the exhaust. But from what I've observed, I need to remove the intermediate catalyst. Will this influence the consumption or electronic injection of the bike???

    Many of us have opened the blocked side of airbox and cut out the CAT so the engine can breath. Many have also removed the SAI function too.

    You will need to update your tune accordingly. TuneECU is your friend  :028:

    There are many custom tunes available via this board that other Tiger users have shared. You can also utilise some of the OEM tunes from here: https://tuneecu.net/Tune_List.html

    Surely in Brazil, the fuel quality is the main issue for you?

    Alternatively, visiting a local tuner or taking your bike to a Triumph dealer are also options.
    Just ask for help if you need any  :031:

    yes, fuel is our biggest villain.
    So I would have to change the bike's ECU? if I withdraw the CAT

    No need to remove ECU, you can connect to it via OBDII socket under the seat and upload a different fuelling map.

    Yep.  The ECU is just a sort of computer and pretty much all modern vehicles have them and use a thing called OBDII (or equivalent) with which you can connect to it, up/download the program that the ECU uses to control how the engine runs, known as a 'Map.  You need a program/app that can understand the ECU language eg tuneecu, an actual computer to run said program on (or smartphone etc) and a cable or wireless interface device to connect the computer to the ECU's OBDII socket.
