    Hi Guys, I disconnected one of the plugs for a test to one of the Lamda sensors so now have the engine light lit, if I disconnect the battery will it go off of does it need to be reset??

    Thanks.

    I bought a second hand Power Commander, but 2017 bikes need some extra modules on the O2 sensors it seems, the guys at Power Commander told me that not all bikes need them and the way to check is by unplugging the O2 and see if it activates the engine light, well mine did so I would need the modules.

    Have to say you have lost on this one, if you are fitting a PC they stop the 02 (lambas) working anyway, After fitting the PC unplug the wiring and tape the plug ends up to stop the shct getting in, and put blanking plugs in the headers.

    That’s interesting, as I’ve got a second hand PCV currently winging its way to me so I’ve been looking on Dynojet site for fitting instructions etc, there’s a product note for the XR stating - ‘ 2017 - 2018 models require two O2 Controller (part number 76125078)’, I tried calling but no answer so I’ve emailed them for clarification and just to check whether my 2019 is affected, the fitting instructions on their site don’t mention anything about this - just to either disconnect the O2 sensors or remove them, I’ll wait to see what they come back with :084:

    Slightly egg on face time...i’m Reading this thread this afternoon...check my emails and cannot find a recite for 02 dongles, now this the down side of too many bikes..

    Get the wife to check the emails, no she can’t find one either, go into the garage check the bike and see I just disconnected them and put tape over what was left.....

    Go into Dynojet website and f... me see a new set of rules for the 17/18 bikes assuming they really are 17/18 models hence have to disconnect to find out if they are...it’s a learning curve for me never mind you guys, too the point it’s only Dynojet that sell the lamba deletes if that is what they are??.

    Regardless it WILL be worth it I can assure you, just a tad more hassle than I had.

    The problem is the cost of those O2 modules, 80 odd quid and you need 2!!!
    Below is the info I got;

    Before to buy them, simply try to unplug the stock O2 sensors, if you don't get FI error on dashboard you don't need to buy/install optimizers.
     
    1) All BMW models from 2004 to 2017 don't need it, just unplug O2 sensors and leave unplugged to stop the ECU closed loop
    2) At the end on 2017 Bmw changed the ECU strategy and when unplug the O2 sensors you get FI error on dasboard, then we build the 76125078 to keep FI light off.
    3) On 2019 Bmw changed again the ECU stategy so even if you install the 76125078 the FI error will switch on after some miles of use, then they updated all previous biked untill 2018.
     
    HTH.

    All depends on ones take in the matter... :001: :015:

    First port of call is obviously Dynojet and the guy you need to talk to is Richard, not only is he very good, but easy to talk too, so i’d Run through the situation before doing anything and i’ll Do some digging my end.
