Bunch of Questions. Mechanical and Electrical

All these questions pertain to a 2009 CBR600rr...

Whats the best place to get my ecu flashed at? The only one I know so far is ECUnleashed and I want to explore other alternatives before making my decision.

Has anyone run q3's or similar road tires (s21's, PP3's, etc) on the track? I'm currently running Q'3's (190/50) on a 5.5 rim. I've hear from several people that having a 190 on a smaller rim causes the tire to multi-radius, leading to sub-par performance in extreme lean angles. Does anyone have experience doing this? Or is it possible to buy a 6.0 rim for my 600?

Does anyone have custom bazzaz maps for their cbr600 that I could ask a few questions about? Specifically if/how it was used to mitigate on/off throttle jerkiness.

Thanks in advance

I don't know how fast of a rider you are but Q3's are good for the track. I use to run Q'2's on my GSXR 600 and I use to run 1:50's at MSRH without a problem. Just make sure they are correctly inflated and allow a couple of laps to achieve good temperature.
Having a bigger tire on a small rim is totally OK. Yes it will change the bike setup but it can be easily fixed but if you are not an LV3 fast rider you won't be able to tell much.
Roger with on road off road charges around 40 bucks to have your bike set up. He will be at the track...

For ECU flashing I recommend contacting Chris at MC Cycles, he's a sponsor on here.

At moderate lap times the tires you have listed above will be just fine.
I would recommend staying with a 180 tire on the 5.5" wheel.
Unless you're the next Ben Spies there's absolutely no benefit to running a 190 on a 600, especially not for track days.

The Bazaaz system can be a PITA. After the ECU is flashed if you're still looking to tune for a couple of issues or go to a quick shifter I prefer the Power Commander V.

We do suspension set ups here at the shop, it's $30.00.

I've had roger set up my suspension. And I usually run 29/29 (cold) on the track. The concern I have with the q3's on my 5.5 rim is that it causes a change in the tire shape. Different to what a 190/50 or 190/55 on a 6.0 rim and also different than a 180/55 on a 5.5 rim. It's not a round shape. It's more of an oval. Leading to a sharper drop off on the sidewall.

Some tires have a more triangular profile, while others are more rounded.
A triangular profile will reach maximum lean quickly/reacts quicker.
A more rounded profile is more liner in turn in.
When doing a suspension set up for the track an eye needs to be looking at the tire profile and overall geometry as well.

Ok. That's a very good point. Last time roger set up my suspension I had pirelli's on. They we definitely much "rounder" more linear turn in
