    Default Honda City 2009 Software Upgrade messed my car

    Hey Guys,

    I need to know if i am the only one with this problem as Honda Point people certainly dont agree with me. So i took my car for a 25k mileage maintenance check. The guy said there is a new software update for my car which will remove the knocking that happened on a few occasions. I said why not.
    Anyways after the software upgrade my car's RPM meter always stay at 900rpm at the minimum.
    Driving in the city areas my car used to give around 350-375 km in a full tank but now it gives 250-300km which is just ridiculous. On highway the fuel consumption is just fine giving me over 500km per full tank.

    I had a little argument at Honda Point and finally they just said its company upgrade, the rpm is supposed to stay at 900 even if AC is off and they cant do anything about it.

    Has this happened to anyone else or am i the only one in this boat?

    Regards,

    XubX

    ^Well i never got that much mileage anywayys. to show the seriousness of my issue look at the following photos. Full tank does less than 250km at around 7km/l.
    I have to stop a lot of times in the city waiting in the car but still this is pathetic

    Well its somebody else's argument and forgive me PW admins for jumping in place of the addressee. But I believe values must be practiced in honor of senior and contributing memebers.

    @Mr. Sohna
    Sir, please keep in mind. PAKWHEELS is NOT a social network by definition.. Its a ground for technical issues and developments, issue resolution through feedback of knowledgeable members so that everyone reading gets benefited. So your jokes and your brotherly gestures don't replace a valid argument. I think you mistook it to facebook where a simple smiley creates wonders. Well it doesnt, not here.

    Coming to your statement about self made engineers, well i would not be doing justice without bringing your above quoted thoughts to the court. Can you please explain what possibly is the difference between the flash file and the software. Because none of your above statements makes any sense. I would love to be enlightened. And we at pakwheels are very good spotters. We can quickly spot whose bluffing with shallow words.

    And to the difference b/w EFI and fuel injection system, please please explain what this mystery is. Perhaps you were referring to the old plunger diesel injections and fuel injection system. Well in that case, due to considerable change of dictionary, I and forced to admit that you are right. But I am sorry, that dictionary doesn't work here.

    PS: Respect senior members. Review your thoughts when posting after reading their membership duration and contribution to the forums.

    Please read the original post once again - slowly without a cigarrette in your mouth and with a cup of tez chai.

    The ECU was never replaced - they flashed it with new parameters, its done all over the world, and is very acceptable - what you defined as tuning is a brick wall here.

    The engine operation is the output of the ECU, (just like a printer is to a CPU) - if you change the operating parameters in the ECU, you change the tune of the engine - in this case its ignition timing retardation to prevent preignition (knock). How does "configuration" change apply here?

    What profession/business are you in - as you consistently are trying to preach about flash file etc.

    To control knocking try a mixture of 80% Super - 20% High Octane fuel It will be gone by that.

    Plz trie to understand what i am saying slowly slowly with out WOMOTING and keep ur mind on that specific point .
    Tuning is not to change the timing of Engine but Tuning involves a lot of configuration to redo.
    A lot of other parameters related to fuel require to change when we say that we r going to do the tuning on ECU engine.
    I know once u come up with that statement ....that tuning is just to chang timing .....................
    Plz relax and trie to understand the basics first.

    and donot think that u r old here and u can know more then any body...else .............

    I give simple statement but people make it difficult because if u don't want to understand any thing u will; raise unnecessary points which make me more to understand my nation.

    This member comes up with the most off the wall concepts that you will know, in another post he came up with a statement that EFI engines do not have injectors, and started to argue that THEY DO NOT HAVE INJECTORS and fuel is mechanically adjusted, to top it all it was a technical help thread of someone elses.

    Now this, What Mr Sohna is saying that engine tuning means engine configuration should be changed, WHY? when the same mechanical setup can cater to nearly every part of the world with different ECU setups, do we need to change something on it to cope with the flash.

    the ECU flash can cater to all operating charecteristics of engine operating requirements, be it run with 10% alcohol mix fuel or with your regular brew 87 RON fuel you buy at the pump.

    Your brain, your boat - whatever rocks it is best for you, I thought PW had a little sensible people on board - but actually saying that wrong is right, and then putting up chinese proverbs along with you learn from anything, anywhere.

    Learn YES, most welcome - but something like 2 and 4 is 6 not 2 and 4 is 9 - then reasoning that if you see 9 upside down its six and hence true. I dont need to prove anything to anyone here, I did not go to Engg school to correct people's concepts on forums neither gather respect, For them the earth can be flat. I wouldnt care less.

    I am shocked to see what you wrote about your fuel consumtion... mere bhai, I had 2009 model and it was giving me 450+ on fuel tank within the city... I use to put 40% hi oct and 60% super... I use to fill the fuel from specific fuel stations...

    I believe you are either feeding your car with terrible fuel or your way of pushing the peddle is hard...

    Honda city 2009 has one of the best fuel average when it comes to 1300cc engines...
