Factory Pro's new Teka SFI will, simply, allow you to make fuel changes on your Suzuki in less than 20 seconds.
No laptop. No palm pilot. No hassle.
Realtime changes - even AS the bike is RUNNING.
Multiple Pro Racing Podium finishes - Mike Smith, Jimmy Moore, Tony Meiring, Team Hooters, EDR Racing and many more. 

Before the Teka SFI came along for the Suzuki, the only realistic choices available to tune the Suzuki were either the venerable Yoshimura "421" 3 position, +/-"10" analog reprogramming box or a power commander.
One, economically cost effective per bike, the  "Yosh box", worked acceptably and reliably for some bikes, but is limited in throttle position resolution and absolute fuel adjustment range. In other words - it worked on a some bikes, allowing enough tuning range for clean and strong running - and worked at well enough to tune several AMA Supersport 750's all the way to podium finishes. At any rate - the "Yosh Box" (still available from Yoshimura), could provide a good running bike on a percentage of Suzuki's. Total tuning cost for shop was labor only. Same for the customer. No parts to buy and install - no warranty issues - no mystery map loss, etc... 

The other tuning scheme possibility was to buy a pc and subscribe to the dream that you could download the perfect map off the internet for your bike and pipe and experience magical perfection in performance. Wow. Cool....  So - now that pretty much everybody in the industry knows that is a sales marketer's dream (selling the sizzle, as they say...)  - we pretty much know that if a downloaded map happens to work perfectly on the bike that you are working on, it's good luck. A Las Vegas gamble, as they say.
So - since the ~$300 - $400 power commander purchase gamble may or may not work really well, depending on how lucky one is, it leaves the pc owner open to only 3 options - ride the bike as is and complain about it (most common), download more maps and keep trying to find a map that works (maybe 5% to 10% of owners) or give up and pay someone else $200 - $500 to make a custom map for his or her bike.
Now, we are talking about a possible $500 to $1000 investment instead of using the Teka SFI to reprogram the stock Suzuki ECU......

For the customer, the Teka SFI provides the means to properly tune, to a fine degree, the original Suzuki Fuel Injection system. The cost per bike? Only the labor time invested.
The Teka SFI has the range of about the equivalent of "4-5 main jets" (it's actually more because the Suzuki ECU accommodates some changes automatically).

SFI remembers and displays the changes you've made (so you can remember what you've already done!)
SFI changes FI mapping when you press the button - so you can hear the idle change while the engine is running - better or worse?
As far as that goes - the idle quality (for some reason) will always be better with the SFI over a Suzuki with a pc installed. Starting, too, is better with the TEKA SFI tuned bike over a pc3r equipped bike.
It's pretty nice when you take off a pc3 and use the SFI to tune the bike - the customer touches the starter button and the bike doesn't grind and maybe backfire before it starts - the drama is gone and the customer is happy...... "Starts just like it did when it was stock! - Thank you!"
SFI will change mixture as the bike is running - as in road testing and richening up the 10% throttle range - no need to stop - change and try - change and try...
All done? Take the SFI off and take off!

And - no. The ECU will NOT lose the map if the battery power is disconnected. Whoever says that doesn't have enough experience to state that (obviously true, because they are wrong). And no, a power commander will still work just fine if the stock Suzuki ECU is not zeroed out. (it's painful to listen to a poor customer who has decided that they are going to try a pc after Teka SFI and the guy who "sold them on the pc" and tells them that the pc "won't work" if the ecu isn't zero.
It's not uncommon to see a Suzuki race team with a semi-tuned Suzuki ecu, with a pc added (because they don't have the ability to  tune the kit ecu and their dynojet dyno can "tune to an af ratio") fine adjusting the fueling with a Teka SFI to make the "tuned to an af ratio" pc mapping work on the track....... for example.

What if there is something really odd in the fuel curve of a highly modified bike and the Teka SFI can't adjust the ECU enough? No big matter - you only have some labor invested and you don't have to deal with a parts return or a disgruntled customer. You tried and it couldn't be done - they must buy an aftermarket "add-on" box  and deal with that cost. 
Better to start with the cost effective SFI method - rather than selling everybody add-on boxes that still need additional tuning anyway.
