I like your choice in parts cams/pipes. As for tuning I would say SERT and explain why. First just for background I have both. The Power Commander will allow you to tune you bike to satisfaction but you will end up wanting to have the dealer flash it anyway because you will be "bumping" the rev limitter from time to time. So after you are done with a PC and then a dealer flash you will have spent the same amount of money as a SERT. Next the SERT will allow you more adjustable options and it is just slightly more complicated than using the PC software.

The power commander is very popular, but its finctions are very limited, and you have a big bulky box you have to find a place to hide on your bike. So I would take the SERT, but the learning curve is much steeper. A useful tool to have for the SERT would be a WEGOII from Daytona Twin tec. With that being said, I would take the Daytona Twin-tec TFCI ECM over any of the other products currently on the market for injected bikes.

RE: se racetuner vs power commander
The power commander is popular because it has been around a long time, has a proven track record and they can supply a half decent MAP file for most combinations. With the PC III usb you can also tune front and rear cyls individually as well as timing corrections. The SERT also allows warm up table adjustment, Rev limit adjustment, Idle adjustment and a few others. There realy is no reason to go to a Twin-tec TFCI unless you are running a radical camshaft that is unsuitable for a speed density fuel system. I also feel it would be likely poor for street use on a heavy loaded bike. The WEGO2 however I feel is a must have tool for anyone who wants to tune there bike correctly. With all that being said and my being obsesive compulsive my TCFI will be in my possesion next week.

I assure you I understand. We can stay simple for this. We have basically 3 types of EFI systems. Mass Air Flow, Speed Density and Alpha Numeric. Of those three there are only 2 that are used on production street vehicles and Alpha Numeric isn't one of the two. On the other hand for racing applications Alpha Numeric takes a rather large piece of the pie but for a normal street engine Mass Air Flow is best for drivability because manifold pressure (or the lack of) is the best way to sense engine load, Not TPS. The basic downfall for Alpha numeric is it only knows load from TPS vs RPM yet your actual load can vary greatly due to gearing and loading. As for price on the TCFI I think its cheap $695 for the whole package. I also believe it is a nice piece and that is why I bought one. To bad this is a short week because I have to wait till next week now to receive it.
I currently own 2 aftermarket ECU’s from Accel. These were made for Accel by a company called DFI located in MI purchased from Hahn racecraft one is a backup and the other is installed on 400+ hp Turbo Charged Drag bike currently parked in my trailer. This runs Speed density with a 3 bar map sensor.
At work I have been using ECU’s from http://www.gems.co.uk/ for the past 4 years and these we use in the Alpha numeric mode. This is a shortcoming but our only option due to the pulse created in the inlet pipe of the rotary engine won’t allow us the option of speed density. This application is also for a small airplane so Mapping done static on the ground using various props still only gets you so far. Each prop rides along a different load line. In the air the load changes due to the prop unloading with air speed (fixed pitch prop) the place you notice this most is in what is called the speed load table. A speed load table tuned to ground operation performed poorly in the wind tunnel. We are also currently working with two other ECU vendors for our application but only using the GEMS in production at this time.
Anyway we all have and can have our own opinions.
All three are good options depending on what you want. The PC likely going to be the cheapest and easiest of the three.

And lets be real here, Speed density and Mass AF ecm's are cheap, dont require alot of expensive hardware and software to operate and have been around for a long time. There isn't anything they do that a good Alpha-N system can do itself.
