Block off plates

Quick reply: No

If you are just doing a slip on I wouldn't bother. If your doing a cat delete I would definitely recommend it.

Sorry I didnt read it well enough. Muffler only no plates needed, If you decat you will have decel popping without the plates.

i have been thinking about why is that, and why it doesnt affect the bike's ecu. I suuddely realized that the tuning is done via wide band at the exhaust tip. If the tuning is done via O2 sensor location then it shouldt be a problem (it is a question more than a statement)

You may be confusing dyno tuning with flashing the ecu.

When dyno tuning, the wide-band O2 sensor (not the factory O2 sensor installed on your bike) measures the air/fuel ratio in the exhaust, since the ais system injects air upstream in the exhaust, it will make getting accurate air/fuel ratio readings impossible.  Injecting more air in the exhaust before the O2 sensor will make the sensor read more lean than what the bike is actually running.

Now if you get your ecu flashed via mail order, there is no dyno tuning involved with your specific bike.  In this case, you wouldn't need to install the block-off plates unless you remove the cat and want to reduce the popping on decel.

Also keep in mind that the "closed loop" mode on the bike where it actually takes readings from the stock O2 sensor and makes adjustments is only a small area of the throttle/rpm range.  I'm not sure exactly what triggers the ais system to inject air into the exhaust, but it may not do that while in closed loop mode, which would allow the stock O2 sensor to get accurate readings during closed loop operation.

I agree, it would be great to have a truly closed-loop system with a wide-band O2 sensor, then when the ecu is flashed, you could simply alter the target afr values to your desire.  This is why I use a powercommander w/autotune and display to take care of the fueling.  I had the ecu flashed by 2WDW so that takes care of disabling the necessary systems as well as their performance/de-restriction tweaks.  But I prefer to create a fuel map specific to my bike.

Yes, but once the ecu is flashed and the O2 sensors are disabled, PCV has full access to entire fuel map.  So it sounds like the PCV was limited by the ecu, not that the PCV is not able to tune that range.

The fuel map created by 2WDW, or any mail order tune for that matter, was not created specifically with your bike.  It was created with the same model bike, but even bikes of the same model with the same mods may require different fueling.

When I got the ECU back, the bike ran great, but I could feel some inconsistency in the just off idle area.  While I would turn the throttle in the 0%-2% area, I could feel the bike "fall on it's face" then pick back up with just very small turn of the throttle.  So rather than sending the ECU back and forth to get it worked out (no doubt that they could have gotten it perfect for me), but I'm a data junkie, so I wanted to do it myself.  When I installed the PCV w/autotune and the display, I was able to verify what I was feeling by watching the display.  I could see when the bike felt "normal" the afr was around 13.5-14, then when I was feeling it "fall on it's face", I could see the afr was up in the 15's close to 16, then when it picked back up, it was back down in the 13.5-14 range.  So all of those afr changes were going on with a very small, but constant throttle movement from closed to 2%.  This allowed me to adjust the fuel map and smooth out that section, it now has a very smooth throttle response in that area.

Truth be told, someone else may not notice that feeling, or may not care.  But it annoyed me enough to want to know why it felt like that.

At WOT, the autotune isn't really making any changes to the 2WDW values, so in my case, it just helped me figure out why I was feeling what I was feeling in the just off-idle throttle area.

On a side note, I used Woolich Racing's values to populate the target afr table for the PCV w/autotune, after all, an autotuned map is only as good as the target afr table use use to generate the fuel map.

I've also got a Suzuki B-King, this is the bike I learned about ECU flashing with and have been working with it for the past several years.  I have the ECU flashed with Woolich Racing Tuned and also use a PCV w/autotune.

I would say the initial 2WDW tune got me 99% of the way there, and an add-on fuel controller is not necessary.  The PCV w/autotune just helped me get it perfect (for me).  And I like being able to see the afr at any given time, so I know what's going on.

Na, I'm sure the flash would have been perfect, had they had my bike with them.  Their tune is awesome, you just can't expect a tune (fuel map) that was created on one bike to be 100% spot on for another bike, even though they may be the same model and have the same mods.  Even though what I have done smoothed mine out, it may not work as well for you, or any other FZ-10 with the same mods.
