Did you actually physically deal with the SAI? Everything I have read says to not disable the SAI unless you physically block it off as well. So that could have caused your issue.

I will say I have a 2012 with the arrow full exhaust and it is extremely responsive. Doesn’t feel any different from my Daytona minus the little bit of power difference of course.

 

SAI works regardless of map. The map simply changes whether it throws a code if you remove it.

As for the map. No one map works great with all bikes. In fact it takes a hugely compromised map to even work well on all stock bikes. Even stock there is a significant different in injectors and combination quality. If you want to know how good a 3-1 Arrow can work you’ll want a custom tune. Actually the same goes for the stock exhaust.

 

i had the triumph supplied map for the 3-1, ran ****. had it dynoed. runs epic.

 

Can you please share the map? what is your VIN number?

 

Nope.

 

I can’t either as my bike is not stock. Daytona cams and a number of small changes.

 

I'm using map from tuneecu which said

Street Triple & Street Tripkle R, Use with Arrow low level 3:1 system. Fuel up to E25. Minimum 91 RON (87 RON/MON)
fuel

http://www.tuneecu.com/Tunes_in_Hex...by_model/all_675 Street Triple/675ccStreet_Triple_Up to VIN 411983/20574Map.zip

 

That’s the basic Triumph map for the 3-1.

 

Arrow 3-1

I've had the Arrow 3-1 with Triumph Arrow tune on my 2010 STR for around 6 years now and the performance is way better than stock. Pulls so hard in top gear that I rarely need to downshift to pass even at low speeds. Keep in mind that the 3-1 drops over 20 lbs of high up weight also. Another nice performance mod is a SuperSprox 520 conversion with 2T larger rear sprocket. My Shorai 18Ah lithium battery is just superb; bike starts first try after the long winter and the battery drops another 5 lbs of high up weight. Last year I cleaned and synchronized the throttle bodies using TuneEcu and the bike runs noticeably smoother. At 50,000 kms the bike performs better than new. The icing on the cake is the Ohlins shock and KyleUsa linear linkage; the handling and ride on fast bumpy backroads is effortless. No need to buy the new one.

 

It’s not about the power. There’s definitely more power with the arrow but throttle control is better with the stock exhaust. However a dyno tune with the Arrow will be smoother and have better control than stock and more power than the Arrow alone.

I’m with you though zero reason to get the new bike. Mine currently has 120hp at the wheel and weighs 360lbs with a full tank. To do that on the new bike would take twice what I put into this one. Mostly because I’d need a power commander.

 

Hi Wayne,


Which Triumph Arrow tune you currently using?

Thanks

 

Triumph Arrow 3-1 tune



Using the 20591 tune recommended for my VIN number. SAIS deselected and block-off plates installed. Speedo is corrected 10.5% to allow for stock error and 2T larger rear sprocket. K&N air filter installed. Fueling is flawless from idle to rev limiter. No dynos around here, but it runs so well I would hate to mess with the map. Btw the sound of the 3-1 is right in the Goldilocks zone; great sound without being obnoxious.

 

I've been nervous about going to an aftermarket exhaust for exactly this reason - heard a lot of reports that the top end is better but no matter what off-the-shelf tune you use, something is lost on the low-end.

 

Whenever people say they lose bottom end it’s either assumed or seat of the pants reporting. When you add top end to a bike it will make the midrange feel weaker even if it’s not. Same for adding midrange but not too end or bottom end. It makes the bottom and top feel weaker.

In my experience with multiple pipes and a lot of dyno work even without changing the map so just using the stock base map a pipe that flows better will improve top end and even bottom to a lesser extent. Simply pulling the intake restrictor was a 1hp gain over the entire rpm range. When I went to the Competition Werkes low pipe it was about 6hp on top and 2 from the bottom up to about 6k. The Arrow 3-1 with the stock map was about the same. However the Arrow with the Arrow map was about 8-10 peak and about 2-3 on the bottom. The Arrow map did not work with the Competition Werkes the stock map was best once adapted. These were all tested on multiple runs as I had a dyno to play with and very little work during the winter months at the time. Daytona cams gave me about 10hp over the Arrow exhaust and another couple hp on the bottom end. Then a dyno run gave me another 3hp peak and a couple midrange same bottom but the on off throttle became like butter no lag no jerk smooth as silk. So my bike went from a stock 92hp to 117hp and 46ftlbs to 54ftlbs. Since the dyno I’ve cut weight out of the drive train which will measure as more power to the wheel since you’re loosing less from weight and drag. I should have about 120hp at the wheel now and maybe another 1ftlb or so.

These bikes really respond well to opening up the exhaust. I did a run with a straight header and it had gains similar to the Arrow.

 

Does it require also an open air filter?

I have an SC project S1 on a Street Triple 2010, and I am thinking of putting the 3-1 Arrow program..
Sound amazing but at 0-20 ΚΜ/Η i feel it somehow dead.

Maybe it was better with the stock exhausts but I am not very sure (placebo effect).

Any ideas?

If am not pleased from the Arrow program, I will go for a manual setup + an open air filter

 

anyone?

 

The arrow 3/1 is not just a silencer, it’s headers with larger id and no cat. The arrow 3/1 tune is for the 3/1 exhaust with stock air filter I’m pretty sure. It was a triumph accessory and I don’t believe triumph offered modified air boxes. And it runs great on my 09.
