    So if you want to remove the cats, you have to ground the white wire going to the engine and all will be fine (on the M13 motor)?

    True. Depends what you wanna do. Heard the wire trick doesn't always work.

    I would rather just get it chipped and add a turbo while I'm at it

    Flip I spoke to Wizerd already. Rivar the restrictive part of the catalytic converter is a honeycomb/coral-ish material that can be broken up and removed as far as I know so I might try that...hkgk

    You will still have the problem with the sensor if you do nothing to it

    Not entirely related to this post, but might be.
    Three tanks of fuel ago I added 50ml, measured, of 2SO to a full tank.
    But even now, every now and then, there is a very noticeable sulphur smell from the exhaust.
    The undiluted 2SO also has a sulphur smell, but not as pronounced.
    Weird thing, I run my RC plane and weedeater 2stroke on the same 2SO, but MUCH higher concentration, and NO sulphur smell.
    Really would like to get to the bottom of this.
    Is it something the CAT does ?

    Sometimes the cats to let off an odor that smells like sulphur, or plain english, eggs.

    Why are you putting 2SO into the tank?

    Talking Re: Jimny - Removing the cats - any difference?

    Hi Rivar,
    Thanks for the reply.
    Many years ago I attended a comp in OZ, and we drove in a Pajero that could switch between LPG, or petrol.
    A few days later, we had problems with the engine.
    Long story short, running on LPG "dries" out the mechanics in the carb, and the local mechie said to start and end the day on petrol, and to add 500mL of 2SO to a full tank of petrol, for the lean times.
    Never had problems for the rest of the time.

    So I figured, why not on a new vehicle, considering I had to replace the carb on a previous vehicle, where the mechie said, "you should have run some 2SO every tank now and then, for lube"
    And that was a number of years back.

    So my theory is, and only mine, that maybe the 2SO will coat metal surfaces with a thin layer of oil, and get into those mechanical movement areas present in most fuel systems.

    Heck, if 2SO can lube a high revving 2 stroke, it can only help in a 4 stroke.
    And if it doesn't bung up the CAT, so what ?

    That is why

    Hi Segal,

    Reviving an old one here, hoping you can help with some info or opinion?


    The Situation:
    I did a de-cat on my 2015 Jimny at a CT shop in December. Since they day it was installed the engine light has been coming on and off (mostly on), and when it occasionally goes off I have very sluggish response between 2500-3200 RPM.

    I have been back to that shop three times to get it fixed - the first time they said it was an engine problem that the Suzuki needed to fix, Suzuki said it as the other shops fault and to take it back. I took it back, the shop replaced it and re-set the error messages. A day later we were back in the same situation, I took it back to the shop, they said it's not their problem, take it to Suzuki.



    The Symptoms:
    • Engine light is almost always on
    • Feels like a gigantic AirCon is being turned on between +/- 2500-3100 RPM - huge power drop



    Wether the problem is the Cat Fooler or not, all these problems didn't exist until the day it was installed. Any ideas on how to solve this Both the shop and Suzuki blame the other.

    MUCH appreciated!

    Ok, went back to the dealership, they are 100% confident it's the O2 sensor that needs replacing. They say every 60000kms or so it should be replaced, we're currently on 54k.

    Replacement is happening next week with Suzuki, will update on the effects.

    Bloody expensive little gadget.

    First time I hear that a O2 sensor needs to be replaced at 60 000km 🤔
