I use PC-V because I installed a different cam,headers,pipes, and intake all at once, and the cam did not have a canned map,So I took it PC to tune in Vegas. I have made minor table adjustments and my bike pulls hard and I'm pleased. Got a good deal on autune and ordered new 18mm bungs for the wide band O2 sensors and now just need to find a competant welder to put into my headers. Everyone I ride with now that has autotune installed have experinced smooth as glass running with both cylinders matched for power and economy. They are getting 4mpg better economy than running without the autotune. Its dyno in can with you all the time you ride. I don't want to see on my handlbars some screen giving me info I can't digest. Either the bike runs good or it doesn't. That vision thing would not help me. Autotune handles the mystery

Ed over in Dallas, http://www.thedynodifference.com/. You will need to call for an appointment. He also sells a tuner for around $250 that he says is just as good as the SERT. He's located just on the other side of TI off 75.

The Fi2000 Power Pro Auto Tuner doesn't have just one tune. It really doesn't have any tune....from the moment you start the bike it reads what the bike is doing and is always changing the mixture. It's always adjusting no matter what you are doing or what the bike is doing it is always evolving. From the very first turn of the key with the power pro I have never had a single pop on decel ever. This thing just plain works as advertised. Hook it up and walk away never to mess with it again.
Im glad its worked good for you and everyone else that ive heard from. I was by no means trying to bag on cobra products, quite the opposite. Ive had their pipes and fi2000r (not the autotune) on another bike and they are a quality made in america company (pipes anyways).
When I was looking at tuners I researched the cobra autotune and it just worried me that if I didnt like the changes it was making there would be no troubleshooting or dyno testing to fix it.
If it continues to get this good of reviews im sure itll be a future heavy hitter in the efi world.

No worries man all is good. I think that's what I worry about to with the flash tuners is that it may get tuned to run great on a Dyno but then take it out into the real world where air temp and pressures areconstantly changing. Some bikes are not gonna stay running perfectly, some do some don't...my luck it won't that's why I went with cobra, and I couldn't be happier.

I'm not sure how that could come about. In the real world, the air temp gets measured as does the pressure in the manifold which is a result of the air pressure. The ECM sees them and adjusts within it's programmed window. IT is not set up to run only at that temp and at that pressure and no other. That is the beauty of EFI. You can run it anywhere they think you are going to run it. On a carb, if it is set for sea level in Siberia and you run it at 10000 feet altitude at 90 degrees, it might not run as well but EFI should.

I am well aware of efi tuning atributes....but the flashed ecm can only adjust so much,
that's why i love the cobra unit it has infinate adjustment possibilities.
.besides if you change anything you need to go have it retuned. some bikes are so finiky that any little change screws it all up.

The Cobra, from what I can see basically only enriches or leans out the fuel. It cannot adjust say idle speed or timing advance. It basically functions like a carburetor. That simplicity does come with a price though. I would prefer to have something that can adjust the entire spectrum of whatever the ECM can.
Again, I am drawing from my car experience. If you do change major things, you have to re-tune it. Usually for smaller items, it can adjust. On an L98, if you change the intake manifold from say stock to a HSR and put headers, you probably will need to re-tune to take advantage of the intake and headers. But if all you change is say the post cat exhaust or an air filter, you are more than likely fine.
I am also not confident on the "no dyno" tune stuff. How do you tune it if you don't adjust with your O2 sensor and see how each tune affects the bike running? That was the problem with me doing my own tuning for my car. I couldn't measure the results of each adjustment. When we had a professional tune it, we can see that a certain tune gave 410 RWHP. Change a parameter and it went to 408 so we know that 410 is the max it can do and the best point. If you don't us a dyno, how did you ascertain which was the best setting for max power? How did you adjust your AFR?

AFR's are adjusted with the WinPV software. I usually make 2-3% changes adding or pulling fuel where it needs it. I then reflash, run and log again to see how the changes worked. I have my tune right where I want it now after about 15 tries.
It all comes down to if you are someone who really wants to get into it, and tune yourself, then get the PV. If you'd rather just plug something in and just have it do whatever in the background and are happy with that, then get one of the others. Like most things it's just a preference.
