Dynoing my 1299S tomorrow

Surely if you get the full Akra with DB killers removed custom tuned it would be have more HP than with the DBs in? I could see why just using the upmap only May have a negative effect because the exhaust is now flowing more than it was when the upmap tune was done maybe?

That is my suspicion too, but with the DP/Akra tune, they are definitely a loss. As mentioned, the bike doesn't need any more power (at least until handling issues are solved), so I won't be spending any money on mine at this point to see if another tune works better. If I get one coming to run on the dyno, will report back.

Actually, it responds very controllably, and the motor is incredibly linear. The difficulty comes simply because there is so much thrust it overwhelms the chassis. The setup issues that plagued some of the 1199's (i.e. headshake and front end instability) are greatly amplified at the increased torque level. I've measured it out, and it appears that the rear ride height on the S is about 10mm lower than the R. Made the adjustment for next time, and we will see if I can get on the throttle earlier. I was initially having headshake trouble even in a straight line. The changes I'd made after riding it the first time made some improvements, but it was still to where people pacing me could literally see the bike moving around.

This directly attributed to the "frameless design"? Also, do you get any head shake relief from steering dampening? I haven't tracked, but have definitely experienced this on aggressive riding occasions so far.

For better or worse, some headshake and moving around seems to be part of the 1299 experience, not sure anyone can dial it out - adding still more power is probably just going to exaggerate the problem which is why I think it's a little nuts dropping $4-5k on an exhaust for this thing

Short wheelbase and all that torque, the front end is light all the time

Have you adjusted your sag? I havent seen another "S" to be sure but how far down in the triples are your forks? I know they vary in the base models.

Im going to assume that Tcelano has his suspension sorted for his purposes and is doing fine tuning on that and leaving the damper for last. Make the big adjustments first then see whats resolved.

Been spending the first few weeks until first service riding in dynamic with settings to "firmer" when hitting twisties and standard for normal riding. I haven't dialed in the sag for fixed or done any real work with it yet.

I was just wondering his opinion on using the block as a major stiffness support/frame and also wondering if the lower chassis maybe needs some sort of aftermarket stiffening.

Bike was 183 hp and 97 ft-lb with stock exhaust. 185 hp and 97 ft-lb after full Akra and Up-map. That sounds disappointing, but all of the gains were in the midrage, and they were actually very impressive, on top of an already very impressive stock tune.

The 1299 Akra Up-map has the best fueling calibration I've yet seen on any Ducati, and maybe any bike for that matter. Way, way better than the messed-up excuse for a AFR plot you get on an 1199 with Termis.

do you mind posting the dyno graph vs speed?

i am interested to compare with my 1199, wants to see where the gains are actually made. as my 1199 is 184.99Hp and 95.70 ft-lbs

What do you have done to it?

I've only been on the bike for about 4 sessions so far where I wasn't instructing, so it's not really sorted yet. Getting closer. Front end is fine when it is in the air, which is a lot

. Bike is more or less OK in point-and-shoot riding, but we have a sweeper where you tip in just after the 2-3 shift, and don't pick up the bike until well into 5th. That sort of thing is scary as hell when the bike isn't behaving. I can go full-throttle on 600's and 750's. Only full throttle on big bore bikes for pro riders with very well sorted machines, not me, and not this bike.

I've played with steering damper settings, but can't tell yet whether stiffer or looser makes it better, as too many other changes happening at the same time. I'm not running dynamic suspension settings, as I want to know what I have. My baseline damping settings that I plugged in where what JPH arrived at after messing with the 1199 at Thunderhill.

Fork height was identical to the 1199R, with the bottom of the top cap right at the top plane of the triple. I have sag set within 1mm of the proven 1199 setup.

Do you think it's generally easier to sort out a conventional twin spar frame open bike like an S1000RR or new R1?

There must be a reason they stay with it in MotoGP and WSBK

full Akrapovic exhaust system and tuneboy ecu with full custom tune.

Absolutely, in my opinion. A lot of the feedback I hear is reflective of this.

I haven't tracked the Pani yet, but hope to get some track time in this summer.

We are all waiting for the results Shilling!!!

I know, but with all those power bands he is going to find he should be back to the computer by now

OK... The final results are in ....

177.79 RWHP and 93.22 ft/lbs torque.

I will be posting the charts when I get into work tomorrow, where I can scan them on a decent color scanner.

My tuner reckons the A/F curve and ratios look like crap and thinks there's another 4-6 hp just in getting the A/F sorted out. My bike is running really rich in certain parts of the rpm range.

So, there's room for improvement without too much work... I would think a RapidBike module would sort it right out...

P.S. At 4,000 rpm, the bike is making 76 ft/lbs of torque..!!! That's ridiculous...

Cheers.

You were right that's about 20 more than the Beemer. I'd imagine 185+ is within reason with a tune.

Grayson · Jun 3, 2015

I will probably go with the rapidbike module with the stock exhaust. Are you planning on doing any type of exhaust?

fzr100098 · Jun 3, 2015

I was hoping for 180 but still healthy numbers

How was the RH?
