    Hey there guys,

    Just thought I would let you know that we have just finished testing with the new Power vision (PV) interface and am extremely satisfied with the results. The new unit has many new parameters unsupported by most other tuners and if you understand them can be extremely efficient tuning tools. Depending on the model of your bike as to the type of oxygen sensors you have, the Autotune is an extremely good tool but you must be aware that there are another dozen inputs that are correcting your fuel tables that you must enable or disable and then correct your tuning style to suit.

    The first test bike was my own Fatbob with cams. compression, exhaust and intake and while the Race tuner SERT had the bike running awesome, the PV gave me better feedback to analyse the engine demmands better. We tuned this completely in Basic mode and had the bike running of the PV screen with good success.

    It was only when we opened the advanced functions that then gave us access to Power enrichment, Air temp corrections, dimensional accelerator and decel functions, O2 feedback (plus others), that we were able to increase our resolution to tuning the engine and pin point which cells were active at any time, that we started to see gains. I will post more info when we have time.

    The second was a 2012 Vrod which was standard with mufflers and an airbox modification. The difference here was much more noticeable although we did start from a standard off the net file (which was extremely poor quality). The mid range stumble, low torque in the mid range and power band style torque curve are all now completely gone. The bike has transformed into something that is now an absolute pleasure to ride and rides more like it twin cam cousin with torque below 4000rpm making it much more rider friendly.

    In short we will be highly reccomending the PV while still extremely happy using teh Race tuner.

    The only caution we encountered when using some of the premapped files available was that many other tuners have chosen to alter

    -knock retard

    -closed loop

    -accel/ decel enrichment

    -closed loop bias

    -rpm limits etc...

    the reason there is a disclaimer every time you load a map that you agree to is because all of the above can and do damage your engine and you need to be extremely mindful and aware of these effect before you load your tune.

    We are now fitting the wideband sensors and autotune unit and will keep you all informed of our findings-

    Cheers- Anthony Rodrigues

     hi,

    putting these tuners on and having dyno tuned is it solely about performace?

    i dont have a tuner, can you still perform work on my bike to make it run at optimum, 

    what is cost ride in ride out?

    thanks

    Hello Robots,

    The answer to your question is has various considerations and a tuner is only the means we use to adjust the fuel, air and ignition functions of a bike to be more suited to what a tuner(person tuning bike) believes is optimum.

    Making changes to airflow by installing better filters, port matching intakes to enhance flow etc, or modifying the exhaust to maximize flow, are all mechanical changes that will make your bike run to its optimum, however the running of your engine is totally relevant to ratios of air flowed relative to fuel and the time and quality of firing of that charge. The more air, the more fuel, the more potential power. Modern engines and management systems have the ability to change these conditions depending upon the load, rpm, air, water temps, air volume and ignition requirements (plus more). It is the setting of these factors that determine the running output, efficiency and conditions (temp etc) of your bike.

    These conditions are set over thousands of parameters to ensure optimal engine efficiency, full throttle is the absolute last range a tuner should be concerned with and you will find that only a small portion of my tuning time is used for absolute full throttle and power. An engine accelerates at hundreds of different speeds and loads every time you start and ride your bike, every gear is different, every bike speed has a different load for wind resistance, road resistance and inertia resistance that a good tuner should make considerations for. Various mixtures also effect the bikes reliability and logevity by directly determining the temperatures the engine will run at, a little more fuel will cool an engine and reduce its frictional losses while too much will wet down the bores (glaze), and potentially destroy your engine from fuelcontamination of the oil. There are hundreds of other factors that need to be considered also.

    To answer your question, If your bike is not running within its optimum fuel and spark ranges a tuner or replacement ecu is the only way to modify the changes within these relative parameters, but theoretically you can manipulate other mechanical factors to alter them directly. The cost of a dyno tune to remap your ecu will range from $400 to $800 depending on the level of modifications of your bike, as these will determine the time needed and difficulty to set the tuner.

    I hope that answers your question????

    Cheers- Ant

     hi,

    thanks for reply, my bike has slip ons, xieds and I just put the hi-flow air box on it

    when I get to your place do you leave bike there for the day? 

    thanks

    Hi Anthony,

    When I started using the Power Vision I too was suprised with the final results. I found  it  very similar to SE pro tuner but with a nicer seat of your pants feel about the bike. My customers gave me the same feedback aswell. I have just finished my 44th Power Vision Dyno tune and still totally enjoy the results. Glad you have had the experience too.

    My regional customers have tried the Auto tune kit. Sort of did its job. Not  impressed though. There is still too many things it doesn't do. We acheived much better results with a full Custom Advance Map / Dyno tune. But as you know, we have to test all the new products as the come along otherwise we may be still fitting and tuning carbies.

    Cheers Brian.
