AR Inconel Install

WAfatboy.
Thanks for the update on the way the bike runs after the tune.
We spent lots of the time tuning the low and mid throttle area.
The last thing we did on your bike was to test with a +5% and -5% trim to the fuel.
The +5% resulted in a drop in power while the -5% produced the same power curve.
We wanted to make sure that the bike would not lean out at high speed.
Even if the ECU does not add extra fuel for the ram air your A/F rations will still be safe.
The wheel speed sensor was disconnected during the dyno testing.

It is a shame that we did not try tuning the bike without the baffles, it would have been nice to see if this changed the power curve.

Did you get to test the cruise control on the ride to the track ?

Do you think that without the baffles you'd see an increase?

Was the tuning done with one or both baffles?

If you were to remove the baffles now with the same tune will it run lean?

Baffles will only effect back pressure not how lean or rich the bike is running.

I believe if you tune the bike inside a 3 sided pyramid with a pentagram drawn on the floor around the work bench while repeating the mantra.... It's not the pipe... it's the fan speed... it's the dyno... it's the tuners fault!

Apparently the work bench should face Mecca for optimum results!

So what were the final exhaust HP #'s with the tune?

George I recall WAF saying it was up 3 HP but I'm not sure if that was up 3 from the slip on or up 3 from the reduced hp figure prior to the tune.

But WAF did quote one of his tuners as saying he could have got better HP if he tuned the slip on that he originally started with.

Please correct me if I'm wrong WAF. No need for Fanboy figures thanks Fanboys.

Lol Gavin... I read it as 3 up from the slips... but I agree it is open to interpretation... and apples to apples Termi vs AR is history.. we will never know now..

So, I have just come home from picking the bike up.

We have been unable to find either a significant increase in peak HP (only gained 3-4hp) over my bike as it was with Termi slips, or, which is more surprising, any real gain in the mid-range.

The only improvement in performance is due to tuning by Justin & Mr Tuneboy working the 40% throttle mapping.

They believe the Termi slips with stock headers would have returned better numbers.

I asked the Owner/Tech, who is not a Ducati dealer, whether he thought there was an performance benefit of the pipe over my Termi slip setup..."No" was the plain answer.

I found this a few pages back George, I hope that answers your last question. More results after WAF hits the Bunbury Dyno around the 6th may.

The AR made 175 with two baffles.
The termi full system on the same day same dyno made around 172 or 173.
The AR made more than the full termi in the upper part of the rev range and the full Termi made a little more at the very bottom of the range.

Baffles do make a difference to the A/F ratio.
Anything that changes the exhaust gas speed and or pressure will change the pulse timing in the exhaust system.
Every bike I have tested with and without baffles shows a richer mixture with the baffles in.

I got my 1199 Base with AR on with RB evo but then minus RB evo today. If you would like to know more about it you can PM me. But I chalk this up to experience lesson learned. Good and bad.

Not wishing to thread jack here but as a sidebar do you intend to have a Termi slip map available for your TB software package for the 1199??

Have you thought about pressing charges against AR for the accusations you don't know what you're doing, which is why the numbers aren't high enough?

Why PM? Why not just share?

WAF does not have a full Termi system just slip ons!

Was this another bike that your quoting figures from wmcdonal?

You learn something new every day, I never would have thought that the exhaust could change the air fuel mix. I thought the exhaust effected just how well it expelled spent gases so that it could take a fresh mix in more efficiently not the mixture ratio.

Where do you work wmcdonal?

I would guess wmcdonal is Wayne McDonald who is Tuneboy, or is someone trying to pseudo impersonate Wayne McDonald.

I'm basically giving you bullets. But okay here goes.

I haven't been reading but here's what I got going on. I haven't gotten mine tuned yet either so here we go. Went to go pick up the bike today as I dropped it off last weekend. Had the inconel exhaust and RB Evo installed (with latest map) and both baffles. First fire up without latest upmap installed and it was running rich throughout low-midrange RPM. Installed latest Ducati ECU upmap and it was still rich. So ok I was like wtf. So reverted to and older AR RB map but still rich again. Ok I'm like f it lets take the RB Evo out. Then it ran way better but a bit rich between 4500-6000RPM. Took a baffle out and it made it even better. So not so rich. I however now decided to go the route with getting the ecu tuned versus using an RB module. This thing has gotten a lot of juice through the low-mid RPMs now though and it sounds so awesome! I don't live near any great tuners so we'll see when I can do that. Ended up toasting my right lower oem fairing on my 2 1/2 boring highway ride home right where the bump is at behind the rear brake lever is. Ended up dremel cutting a chunk out and probably a little more as it was not the plastic I could move but the fitment of the pipe. I won't have time to fine tune it till later but it looks ok....kinda like a ..... shaped now though LOL.

Realistically, I'm happy with the AR Exhaust...just that. RB EVO thumbs down. I figured I'd buy both as a complete package and not have to mess with anything. I'm not looking for big numbers just good performance all around. So lesson learned there. So I'm going to look at getting the ECU tuned instead. Just don't know where to go. I'm in Eastern Iowa so surrounding states is not out of the question but seriously I wanted to avoid that but to be expected when things don't work. My dealer/tech was super awesome today and I worked with him to tear out the RB unit and put some extra tape around the engine to not heat up the oil so much. He didn't charge me anything and I was there from 10:30AM to 3PM. My dealer is the only one in the state but he's a super guy and wouldn't buy anywhere else. Too bad he doesn't dyno hehehe.

I'm tired from riding home and going to get some martini's and then head out for a long ride tomorrow. Oh and for damn sure this thing needs a heat shield when the engine is just idling after a riding and it's heated up. But it definitely does cool down super fast when you cutoff the engine.

Can we actually get some straight answers from anyone?

Mr Tune boy please let me know was that WAFs bike that you compared the AR system with the Full Termi?

WAFs bike was only running one baffle I am sure. Now your saying two?

please some straight up responses would be really nice
