Hi All, I have had my 1199S Panigale just over a month now and due to the shocking weather I thought I would take advantage and do a bit of cleaning. I removed the lower exhaust silencer to give it a proper clean up. In doing so I noticed the exhaust valve cable has been disconnected. The valve is in the full open position as it will be with the cable discounted and moves freely on the spring. The cable is still there but adjusted to remove all the slack. So my question is why would you do this and would it not show a fault on the dash? Cheers for any advise.
I would think a previous owner has disconnected the connector to the exhaust valve servo and fitted a Exhaust Servo Eliminator... The valves default to the open position. I have fitted one and removed the whole assembly on our 1198 and Monster wwhich is the best way to do it (its suprising how much the motors etc... weigh), the bikes run much better at lower revs and sound much better as the valves are continually open too... I haven't had chance to have a look to see what the current state of play is on our 1199 Panigale yet but I'll be doing the same with that if it hasn't got an eliminator fitted already. I believe removing the motor and cables isn't quite as easy on the Panigales though which may explain why yours are still in place??
Disagree @Old rider? As I have yet to look at the state of play with the exhaust valves on the Tricolore I would be interested to hear any experience and advice you can offer. Do the Panigale's differ from the setup I have already come across on the 1198 and Monster?
Hi Ben, Thanks for your reply and the info. The servo on my bike is still electrically connected as I can here it when the ignition is turned on. I haven’t had a chance to look inside there the servo is located but I imagine the cable has been disconnected from that side as well. I just wasn’t sure why it would be disconnected. I might try reconnecting it just to see what the difference is.
Does the motor cycle, or try to when you key on? If not, then it's most likely been turned off in SW. Either reflashed, or had the Termis removed but the DP mapping left in. What's the welcome message on the screen? If "racing" then most likely DP mapping..
Hi Nelly, Yes the servo cycles when the ignition is turn on and the welcome screen is just the Ducati logo. I’ll take the servo housing off and see what’s going on in there.
It's probably been disconnected in the past if the valve has stuck in the past, or in the belief it improves performance then? It'll register an error in memory, but as the motor is cycling it won't elevate to a dash warning. If all seems well, hook it back up and see if it works ok.
@nelly Quick question for you on this one following your comments above... As mentioned above, I haven't looked at what state my Tricolore Exhaust Valve setup is but I do obviously have the Termignoni's and Up map... Screen displays 'Racing' when the ignition is turned on Does the DP Racing upmap disable the Exhaust Valve function in the ECU programme so the Exhaust valve is permanently open (as it would be if I were to fit a Healtech ESE)?
Yep. In fairness, if the kit is fitted correctly, then the whole motor assembly and cable is removed and the connector fitted with a blanking plug in the kit.
This may not be relevant, but on the Multistrada the 2010 to 2012 (non twin spark) model the software showed a fault if the servo couldn't move the correct amount of 90° from open to close. I think it was sprung shut (??). To defeat it you needed to force it open and fit either an electronic defeat or a cam type metal block to mimic the correct movement. On the later models 2013-2014 (Twin spark, non DVT) only a permanently shut exhaust valve showed as a fault, one that was always open did not show a fault. I've no knowledge of the DVT model. I assume some of the software modules are common in code function, if not actual code.
there is plenty written on this forum about it, basically the servo shuts the flap if cruising at around 3o mph. Its only there for ride by noise restrictions. It serves as nothing else. As long as the servo is turning, it wont show a fault. I just cut my cable until I fit the termis. You can just pop the cable nipple out, or remove the cable. When you upmap the bike with a full system the upmap removes the servo part of the ecu, and you can remove the servo and cables, and the kit includes a blank for the electrical connector. Dont re-instate the servo/flap action, it just holds the heat and gasses in, and everything goes wierdly quiet at 30.
Excellent, thanks for confirming I need this weather to bloody improve so I can get out in the garage and have a look, it could well be in the box of original bits that came it and I've not seen it...
No worries, just wasn't sure if I was missing some vital info in assuming it was a similar arrangement to what I'm familiar with
Thanks Flatfish, I might just reconnect it to satisfy my curiosity to the sound levels. Thanks for the advise and I’ll let you know how it goes.
