Hi mate, yes it is spring loaded in the open position so that’s handy. I thought the later Daytonas ECU’s were locked so could only be mapped by triumph? and it hasn’t got the baffle fitted, perhaps it sounds more intake in the video as I’m in front of the exhaust?
They were locked when they first appeared in 2013 and the old Windows version of tuneecu wouldn't work, so I had to use dealertool originally to connect to the bike, but that doesn't support remapping, tuneecu cracked it some years ago including remapping, with the correct Bluetooth adaptor. I think You're right about the whistling noise, and my arrow I suspect probably needs repackaging, its definitely got louder over 23,000 Miles, but luckily my hearings getting worse so it balances out.
We’ll now I’m a bit confused as I’ve just fitted the arrow can with exup disconnected and it revved freely. the exup valve on the arrow can be moved by hand so it’s not seized, and I’d set this up using dealertool as initially I had a fault. perhaps I just need to set it up again and see what happens then
This is turning out to be an absolute nightmare now. I think I’ve just ruined my exup servomotor as it’s pulled one of the cables all the way in when the ignition came on as part of the test with the exup valve disconnected. Using dealertool to set the exup to park position or open/close isn’t resulting in any movement in the cables. to be honest I wish I’d never bought the arrow now, it’s causing too many issues
Good news is, it looks like it was the exup all along, which would normally be easy to sort. Unless you really want the exup working again, I would leave it disconnected and get a servo buddy to clear the CEL, or my real solution would be get Tuneecu, you can disable the exup and load the correct Arrow map in one go. I know people talk about loss of midrange or low down power but honestly I didn't notice any difference in that regard, only more noise, which I think is the main function of the exup anyway, if anything losing the restriction should add to the performance as you can see the fuel trims adding slightly more fuel because its flowing more air. If you want it working again and its not moving at the moment (presuming no fault codes) you may need to remove the servo and maybe see if somethings jammed or over travelled maybe, never had mine off so not sure, looking at the manual though its a similar arrangement to the other end, you can remove the two cables from the servo actuator, then maybe see if it will reset position with Dealertool. I think its a bit unfair to blame the Arrow, don't give up on it yet.
Ideally I’d like the exup in place as I’m a bit OCD and don’t like straying too much from original. I’ve removed the exup servo and found the motor have wound all the way round which has tensioned one cable to the max, and the other has lost all its tension and come off of the cam. I’m going to try and reset it all, and if not will get another exup servo. Regarding tuneecu, what adaptor/software version are you using for your Daytona? p.s apologies to the arrow, just my temper talking
FYI when I bought replaced my headers it took me ages to set the exup correctly. I used ecutune and with that you can run a test on the valve to make sure it’s opens and closes correctly. Sent from my iPhone using 675.cc
hopefully you'll get it to reset, it shouldn't have done any permanent damage. if it comes to it somebody on here will probably have a good one they've removed or disabled. I ran with the exup working as standard (and Arrow) since 2014 and only tried disabling it a few years ago, partly just for a change as the bike had been the same for years, and partly after buying the Thruxton R I wasn't riding the Daytona as much and the extra noise added a bit to the whole experience. Regarding Tuneecu I'm using whatever the latest Android version is, can't remember the version no., you need to download it directly from the developer, its not on Google Play Store anymore and unfortunately its just gone up in price from 10eu to 25eu for the standard license which allows you to use it on up to 5 bikes. The Bluetooth adaptor I use is the OBDLink LX, there are some cheaper ones that will let you perform the test & maintenance functions and read/reset codes but to install maps you need the OBDLink LX or MX or MX+.
So I have an update. I refitted the exup servo and adjusted with dealertool but it’s still the same. Watching the valve as I rev the bike, the valve is actually closing on throttle input so is backwards! But here’s the confusing part, I have the cables the correct way around (the closing cable at the “top” like the diagram in the handbook shows. And when I refit the standard can I fit the cables the same way and it’s fine? The valve orientation (which way it opens and closes) is also the same on the arrow/standard can. How can this possibly happen, am I missing something stupid here?…
Does anybody know if the servo motors can be manually turned to relieve the tension on the cables? I have 2 servo motors and one of them the “open” cable is all the way in so cannot possibly connect it to the valve. If I just connect the “closed” cable to the valve and plug the motor in and then cycle the ignition it operates but pulls the cable all the way back in again so it cannot be fitted to the valve
Would anybody be able to grab a photo of their exup Cable slack on their 13+ Daytona for me at all? I’m wondering if I have too much slack in the close cable meaning the valve cannot open fast enough, causing it to choke up. Really cannot think what else it could be. there seems to be contradiction in how much slack there should be, my handbook states 12-14mm but thats impossible, more like 25mm gap when the cables are pinched together. I know that the triumph software actually has a live adjustment readout where as dealertool doesn’t.
I'll check mine in a bit if you can hang on, when i've had to adjust the cable tension (exup CEL's) I couldn't get anywhere near the suggested setting in the manual either, and surely everybody's "squeeze" will be different anyway. I know you don't have error codes but when I had P1080 faults after setting the mid position I'd watch the start up check and you could usually gauge if the servo was struggling to achieve the fully open or closed position, then I'd slacken off the opposing cable to allow it to move a bit further, it was a bit trial and error though. Because mines disabled i can only give you a measurement with the valve open.
That’s fine, thanks in advance. Yeah it seems to be a minefield adjusting these things! I just assumed the servo would see the valve open/closed end stops and account for a little cable slack by seeing the motor resistance as it’s operating the valve.
Don't know if these are any help, suppose it depends on the adjustment at the other end if there is any, I've never had my servo off. View attachment 54717 View attachment 54718 Thats in the open position, cable adjuster on the left is the "top" closing cable, which is the bottom cable on the servo. The manual shows the tension measurement in the open position, mine measures approx 22mm (centre to centre), maybe their 12-14mm should be 22-24mm, like I said i've never really gone off the measurement, just trial and error, I will say though it normally needs to be slacker than you'd think. If you need it in another position I'd have to connect to Tuneecu, but not sure it would even do the mid point set up as its disabled in the map, I'd have to send the map again with it enabled.
They’re great thank you for those. I shall have another play. I think I’m going to disconnect the cables from the valve, remove all of the slack from each and then re-adjust. Thanks again, will update once done
Just added some measurements to the pics, don't know if it'll help. I'll leave the cover off for now, but unfortunately I have to move two bikes around the kitchen to get access to that side
I’m currently playing around with the adjustment but to no avail. What I have noticed is that the exup cycles 3 times when the ignition is powered up, should it do this 3 times or just the once?
Okay I’m at my wits end with this exup. Played around with the adjustment, no good. fitted the standard can and adjusted, no good. fitted a spare exup servo and cables and adjusted, no good. I think I’m going to take it to triumph and let them adjust it as I’m fed up spending my evenings and weekends rotating cable adjusters for it to still not work
@Brad675R I see you're only 70 miles from Clive Wood in Swineshead, Lincolnshire. He's a genius with these, will be far cheaper than triumph, probably has any parts needed in stock and will be able to show you what the issue is If it was my bike and money, I'd take it there....as I already do. Sorry to see you have such a frustrating time. Good luck. Let us know how you get on.
