    Hi guys,

    Finally have a few spare $$$ after my house build and have booked my bike into Trivett's @ Alexandria for dyno tuning.  I figure with the upgrades I've made to the engine, would be great to get it 100% right and hopefully improve the performance and longevity of the bike!!

    I'm fairly new to the concept of the dyno and am keen to understand whether anyone on here has been to Trivett's and what their experience was like? I did some digging myself and looks like the prices vary from shop to shop to shop, however most prices range from $400 - $650 to tune my bike.  She goes in on 22 October, he wants it for two days (seems reasonble) and was really informative throughout my questions.  I'm going to Trivett'spartly because I work in North Sydney can drop it off on Monday morning and shoot across with minimal fuss and pick her up in the same way!!

    Any commentary and feedback would be greatly appreciated.

    Cheers

    Waz

    That price seems about right too....There is a thread 'somewhere' about the 10-15 questions (with answers) that you should ask your Dyno man to see if he knows his stuff...Darned if i can find it now.

    I'd go for a Auto Tuner, that way your bikes not thrash, and you can change things around without the hassle of getting it Dynoed every time..........
    my 2 cents worth..............

    i will be interested to see as well  . with the 1250 kit & N4 cams  result , see if they can put a nock sensor on her  to test for pinking  when they tune , & let us know if she wanted too pinking & they would have to retard the timing , my as well get your bucks worth

    Not my work, but located elsewhere....

    Gentleman here are five questions you can ask your tuner to see what his skill level is without being conspicuous. These are 5 simple questions that a good experienced tuner can and will be able to spit out the answers correctly and without a great deal of thought and the whole time your asking themthe questions it will seem like a general conversation of you getting a little knowledge of the tuningprocedures from him.If your tuner can't answer all, or any, of these questions it's time for you to search out another shop.

    1) How long will my bike be on the Dyno to tune the SERT?
    (answer) 4 to 5 hours

    2)How many Dyno runs will you have to make to finish a tune?
    (answer) 50 to 70 on a average

    3) What are people talking about when they say you have to SYNCHRONIZE the VE tables?
    (answer) By Synchronizing the VE Table to the Fuel Table your telling the ECM the new air flow through the motor fromthe mods you made.

    4) I heard something about a Step Test, can you tell me what that is?
    (answer) The Step Test is a program in the winPEP 7 software (Dyno Software) that allows us to sample the AFR longer for a better reading at 2%, 5%, 7%, 10%, and 15% Throttle Position. This is where the bike lives so we want a good AFR sample to make our edits.

    5) Do you change the AFR Table to one value as you tune?
    (answer) Yes, 13.2. This makes it easier to synchronize the VE Table.


    6) When was the last time the o2 sensor was calibrated or checked for the correct reading?
    (answer) check for accuracy every 5 to 6 tunes.....replace the sensor after 20 to 25 tunes

    If your tuner can answer these simple questions chances are (99%) you will get a good tune. I hope this will give you all a better idea who your trusting your $20,000.00 investment with.

    Just trying to help!
    Doc

    PS. If they don't answer all of the questions correctly, PLEASE give them my phone number for training -it's in my signature.

    Update to tuning......The TTS Mastertune V-Tune program will indeed cut down on the number of runs to do a complete tune. While the V-Tune process is being done there are no Dyno Runs being recorded, however, after the V-Tune process is completed there is still a need to optimize the Timing Tables, check for detonation, and decel popping etc. With this said there should be 15 to 20 Dyno pulls recorded.

      i use to use N4 but i also had pinking problems  over 9 to 1 comp ratio into 1200 sporties   ( pinking is not the colour  it's the right  word  to descride detonation in a combustion chamber, pinging is like sonar , bip bip bip bip dong , )    N4 have & early open lobe centre on the inlet
