I've been toying with the idea of purchasing a PC II/III for my TT600, but I wanted to get some more info. on those and tune boys first. A PC actually replaces something doesn't it? Whereas the tune boy just tunes the computer that's on the bike?

Which one do you prefer and why? Just curious how they are different.

A Power Commander modifies the output from your ECU. It is a device that attaches to the bike and plugs into the wiring. TuneBoy reprograms the map in the ECU without anything added to the bike. You can reload old maps, stock maps, or other people's maps into your bike to see what you like best. You can use Power Commander maps with it. You can also perform diagnostic tests like the Triumph gameboy tool that the dealers have, so you can read trouble codes, for example. The only drawback to TuneBoy that I know of is that you need to be able to place a computer close enough to the bike to reach the ECU with a 6' or so cable. If you have a laptop or can put your desktop in the garage (or the bike inside next to the computer), then TuneBoy is the way to go in my opinion. I have been using it for a couple of years now, and I am very happy with it. I have really fouled up my bike, then figured it all back out. It is a whole lot of fun if you like to twiddle with machinery. If you want to set it and forget it, either one is fine. I think the Power Commander may come with some kind of map already loaded. TuneBoy only does what you tell it to do and there is no map included with the software. You can get maps from t595.net, but most of them are out of date. The best TuneBoy map for TT600s is for the specific cam and exhaust arrangement that is unique to 2000 models.

Thanks for the feedback Will. I did some research last night, and came to the same conclusion: TuneBoy looks like the way to go! Esp. if you're like us and you love to tinker w/ *****. Now I just need to decide if my TT w/ 16K on the odo is worth the $310. Maybe someone out there has a used one....... too bad you got another TT!

Will · 09-26-2005

A TT600 with 16K is barely broken in! My "new" one has 17K on it.

But what about the S4. Also, is a aftermarket exhaust needed inable to get the performance out of the $310? If so another few $$$ added to the price.

Retuning takes advantage of whatever setup you have. If you have the stock can and filter, then you can still benefit by tuning out some wierd timing and lean conditions the factory has to put in for sound and emissions regulations. If you have an open can and free flowing filter, then you pretty much have to remap to take advantage of better breathing. I would look at it the other way around. If you have the stock setup, then you can spend money to map or not. If you change from stock, you pretty much have to spend money to remap.

The Tuneboy software and cable work on pretty much all FI Triumphs so if you switch models or have more than one all you need is a new map.

My S4 is completely stock and retuning it has filled in the 4000rpm power hole, reduced buzziness on the freeway, and pretty much increased power everywhere. Midrange is so good now that I rarely use the top end unless I get lazy and don't feel like shifting.

Sweet!! So if I ever get my paws on a new 675 or a D650 down the road, I can use the existing cable and software? On any Triumph? Hot darnn, guess I'll keep riding these things......

Firebolter · 10-05-2005

Not to sure about the D675. It has a different map for each of the three TB's, so tuning for it will be different than current EFI systems where you only have one map.

I'm sure within 6 months to a year, some one will come out with tuning toys for the D675. But the EFI on that bike is much more robust than those to date on bikes, well except Moto Gp bikes and such.

Tuneboy only works on Sagem FI. The D600 and D650 are a different type. It won't work on those models.
