      It depends on what you want out of your bike. If you want more/smoother power band, more efficient running bike, then I'd say at least do a bench flash. If you want to take it to the next level, then I'd suggest removing cat and getting it all dialed in on a dyno for best results 👌

    Evidence base excellent content ! Truly informative and confidence inspiring in your expertise !
    I have Ackrapovic dual slip ons (with cats) waiting to be installed on a 2022 ZX14R, however a dealership advised ECU flash and tune is not worth the cost v gain.
    Your content proves otherwise, however if my only further concern is reliability & additional wear
    Questions : For example would one expect any maintenence, reliability or wear impact due to ignition advance changes ? Can I leave the O2 sensor in on a tune up such a you illustrated for ZX14r ?

    • @provenpowercycles
      @provenpowercycles  7 หลายเดือนก่อน +1

      Thanks for the good words. The flash still helps even though you are retaining the cat. You can alter:
      IAP Fuel Maps
      TPS Fuel Maps
      Ignition Timing Maps
      Secondary Throttle Plate (STP) Opening Maps
      Fuel Trim Map/s
      Idle RPM
      RPM Limiter
      Fan Temperature
      Quickshifter - (Requires Race Tools)
      Launch Control - (Requires Race Tools)
      Disable Stock O2 Sensor
      Disable Deceleration Fuel Cut
      Disable Top Speed Limiter
      All through the ecu. So even if you don't get a tune, you can still utilize other aspects of an ecu flash

    I have a video request i have always wondered how the graphs look with 1. A mail in tune, cat delete and the o2 sensor still connected versus same as 1. But with the o2 sensor disconnected. I know the sensor should be disconnected but I have always wondered the power curve difference between the two.

    • @QuicKurtZX14R
      @QuicKurtZX14R 8 หลายเดือนก่อน +1

      The factory O2 sensor only controls low throttle positions and from roughly 6k RPM and lower, above 1/4 throttle the factory O2 has no effect on almost all new bikes, the BMW 1000RR is one exception to this.

    • @provenpowercycles
      @provenpowercycles  7 หลายเดือนก่อน +2

      What Quickkurt said... the o2 sensor doesn't mess with the heavy throttle settings. The o2 sensors on newer bikes are getting more and more control and it's getting harder and harder to get around these built in settings for emissions control.
      So to answer your question, it wouldn't change at all in the full throttle dyno graph.
      Now if we tested a partial throttle (say 20% range or so) it would most likely be a massive difference.

    Just a question I was wondering how do you tune a bike that has ram air on a dyno? It would seem the faster you went the more air the intake gets and the afr would lean out correct? I was just curious because it seems like a bike standing still on dyno and a bike going down the road have much different air box pressure. Thanks for your time!

    • @SKEEZOTHEREALSKEEZO

    • @johnnyappleseedz422
      @johnnyappleseedz422 8 หลายเดือนก่อน

      @@SKEEZOTHEREALSKEEZO The tune may be done the same way, but the tune on a dyno does not account for velocity of ram air at 100+ mph where the AFR will certainly change. Maybe not by much, but it will change. A good tuner knows this and adjusts accordingly at the higher spectrum of throttle position and RPMs. Most I see is an AFR of 'about' 12.8 at WOT. But this may vary due to regional location, altitude, and temperatures. And in all my time riding, I've only seen one dyno that had some built in ram air effect where the faster you spun the rear wheel, the more air was forced into the snout of the bike. Would this make a difference than a floor fan spinning at a constant rate? I would think yes. How much of a difference, I cannot say.

    • @provenpowercycles
      @provenpowercycles  7 หลายเดือนก่อน

      This dyno doesn't account for ram air. I have a pretty decent squirrel fan that pushes out a decent velocity but no where near 100+ mph air.
      With that being said there are compensation tables built into the ecu (on some bikes) where it calculates fuel changes based on the amount of ram air at any given rpm.
      The proper way to fully tune a bike is to get it close on dyno then go take it and datalog on street/track and make small changes accordingly. 🤙
      Hope that helped answer your question.

      @mrshazam. I would say listen to the questions they ask you primarily. They should be getting to know your bike, the mods done, what kind of rider you are, mileage, etc.
      Questions you could ask the tuner are, how long they have been doing it, how long do their tuning sessions take, what is their process exactly? Do they tune partial throttle or only full throttle/heavy throttle settings?

      They make auto tuners for bikes but most of them don't work very well from what I've learned. If you shell out a few thousand dollars you can run a standalone ecu system (such as motec, maxx, haltech, holley, fuel tech, etc) and auto tune through those. They work great compared to the lower end/ cheaper setups.

    My wife has a ninja h2 sx se plus with brocks mail in tune, brocks full exhaust and runs good but the quick shifter seems rough down low. Cold start is rich because I see black smoke when rev up until it warms up and then it goes away. Is there anything she can gain by having you put it on the dyno to verify af ratio and hp? We bought the bike with 2,700 miles as it was too much for the previous owner. owner said it was making 240hp but we never say a dyno to prove his claims.

    • @provenpowercycles
      @provenpowercycles  7 หลายเดือนก่อน

    • @johnnyappleseedz422
      @johnnyappleseedz422 8 หลายเดือนก่อน

      Not knowing what point of the video you are referencing, QS issues 'could be' the mechanical operation of the quick-shifter itself being a standard Kawasaki quick-shifter as compared to high end motorcycles like Ducati; or, the quick-shifter needs adjustment in electrical timing such as the milliseconds need to be dialed in (down) to achieve a faster shift response. Take a look at any Dragy slip and you will see the speed line correlates to the acceleration line. If you see a dip in that line, it is most likely where the shift is happening. The larger the drop in that line, the longer the shift is taking to actuate. (Higher milliseconds). The lower the milliseconds that can SAFELY actuate the shift, the faster (less interruption) of speed and acceleration. My bike is shifting at 45 milliseconds. To give a greater perspective, one (1) second is 1000 milliseconds (ms). Half a second is 500 ms. 1/4 of a second is 250ms. The human eye can blink on average, 100 milliseconds. My shift actuation is safely set at 45 milliseconds. In stock form, most bikes are about 100ms to 120ms. So, for every gear you are shifting in a race, you may be losing an extra 55-75ms. May not seem like much, but it 100% makes a difference. And that loss in time equates to a slower Dragy pull from 60-130 for each gear you are shifting through. Lower ms, lower times.

    • @provenpowercycles
      @provenpowercycles  7 หลายเดือนก่อน +1

      These new Gen 6 ZX10Rs have a very large quickshifter at high rpm and heavy throttle settings. In the program, they show we can alter sensitivity and kill time settings. However, when we make adjustments to those settings, they aren't really changing. We've tried quiet a few variations all yielding same results at higher rpm and heavy throttle.

    It might be a bit disingenuous to give your baseline numbers on a de-cat bike with stock tune. I guarantee it would have made a bit more hp with the stock exhaust. Sounds weird but that’s what I’ve seen with my R1 and some other modern Superbikes.
    Not to mention with an Akrapovic full system on a 2020 Gixer 1k, the db killer only resulted in a .06 hp loss up top and a 3 hp loss in the midrange. That was Superbike world champion Sylvain Guintoli’s personal bike. It’s all subjective.

    • @johnnyappleseedz422
      @johnnyappleseedz422 8 หลายเดือนก่อน

      What bike do you have? And, what do you mean by stutter? It could be a section of TPS/RPMs that need to be smoothed out if the surrounding cells are not aligned to a certain extend (smooth) so the AFRs may be going up and down. Try and slowly roll on the throttle; slowly, and see where the stutter begins and at what RPMs it ends. Note your throttle position; guesstimate. My hunch is it is low, around 4,000-6,000 RPMs around 10-15% throttle. If it is higher than that, ask yourself "What changed since this started happening?" Changed the exhaust, got a tune, difference gas, major service (spark plugs, etc).

      "I highly doubt it." Then please post your own video and prove his video to be correct or to be bullshit. A db killer will restrict airflow; as do most stock exhaust systems because they must meet rigid emissions. That's why there are aftermarket companies making aftermarket exhausts to open up exhaust scavenging for greater power and almost all say "Not Street Legal." However, there must be a balance between fully open exhaust and correct backpressure; otherwise, you lose horsepower or torque or it just shifts elsewhere. But people like myself who are trying to learn gain a great deal out of his talking. And if you didn't know, you can always Fast Forward the video. BTW, Chris Moore is a "talker" too. So is Brock Davidson. And I've learned a great deal from all three tuners. That is a fact.
