Stock 2010 on dyno
« on: 26 October, 2012, 11:02:44 PM »
EDIT: I HIGHLY RECOMMEND USING THE UPDATED TUNE IN POST #24.


I put my 2010 Tiger on the dyno today to get some baseline runs in.   Saw a few opportunities and made some adjustments while I was there.  I made the changes then downloaded the adjusted map.  Adapt and re-run on the dyno.  Didn't intend to do a full on tune job so did a total of 3 sets of changes/ downloads, but got things significantly improved.

Higher throttle openings were actually pretty close compared to other stock Triumphs I have seen, so only made a few tweaks.  Gained a few ft-lb here and there, probably 3-5% increase in output.

The real surprise was in the lower throttle openings.  It was super lean around 30% TPS.  Fixing this improved midrange output by 8-11 ft-lb, close to 30% increase!!

Here is a graph with the stock run at 30%, then the first change.



I can defiantly feel the improved midrange pull during roll on.

Ill attach the updated tune in case anyone wants to try it out.  Normal disclaimers apply, proceed at your own risk. 
Specs:
2010 Tiger 1050, bone stock
SAI mechanically blocked (to prevent dilution)
Fresh US 89 octane
11,000 miles ( 12k svc already done with new oem filter)
20548 base tune

I am surprised on the torque fall off.
Mine is a very flat line from low to high rpm.

Your tweaking did improve the power delivery from the stock tune.
Good job.

What did the HP look like before and after your tweak.

Keep in mind that graph is at 30% throttle,which is why it drops off.  At part throttle you are looking for a smooth curve.  You can see how the mixture fluctuates in the same are the torque curve fluctuates (and output drops) that is a result of lean mixture.

I don't worry about peak HP numbers because it's mostly irrelevant. How often are you at the peak RPM range? ...less than % for most of us. Midrange is king. That's what you feel when you roll the throttle to pass, accelerate on the freeway, and pass your friends coming out of the turns.

The uncorrected HP went from 93 to 96, which was lower than i expected for this dyno. My bone stock Daytona 675 put down 106 on the same dyno last year.

  Your points on the throttle position are spot on.
Your numbers are surprising when compared to the Daytona.

AFR certainly looks better  :169:. I always felt, however, that the real problem on a stock bike was in the low throttle/low revs area, i.e. the "infamous" snatch! I was always happy enough with the cruising/acceleration of mine (once I stopped it pinging!!).

"snatcyhy" is such a subjective tern..one I've never really heard used until i started trolling triumph motorcycle forums. I've generally understood it to mean the "on-off" effect when going from closed to open throttle, primarily at parking lot type speeds.

I've just grown accustomed to it, using throttle control andthe clutch. My tiger does this, a does the Daytona and Striple. It's tame compared to those.

I reinstalled my stock pipe and loaded your tune. Running it for about 2 weeks on variable situations (commuting in the city, 500km trip, rainy days).

Its great.
Ok there wasn't any significant power increase but it was noticably working better than the stock 20548.

Thank you Dave.

The tiger is going in for the winter. Then decat and Indy's tune are coming.

  Before you do the mod's take a final ride with yours.  Take notes.
Install the bit's load my tune and take another ride.
Love to hear what you think about the difference between them.

Sweet.... Im glad it was useful.  Bone stock before any tuning the WOT readings were actually pretty good.  Most of the improvement to be had was midrange part throttle.

Saw the same thing yesterday on a stock Tiger,did a run at 100% then at 20% to show the owner why he should become acquainted with Tune Edit. Both runs were lean in lower revs, the 20% esp so. And it was a bit rich up top in 100%.He showed 96 HP too.
