Possibly dropped termi UP Map?? Engine warning light, spluttering under load.

I've currently got an engine warning light and the bike isn't running as it should, spluttering badly once under load. It otherwise runs fine. The error light goes out on turning the bike off and comes on again when coming on load, if I dont ask for power then it seems to stay off for a while but generally does come on at some point. My local dealer Snell Performance plugged in the diagnostics and it is showing a exhaust valve error even though the exhaust valve has been removed for the Termis install. They advised replugging the UP Map key to do the mapping again as it seems to have possibly reverted to the base map and is expecting the exhaust valve to be there. It seems I do not have it and the previous owner also does not have it or remember getting it. He gave me the original exhausts and valve in the box from the install but no map key. I also checked with the Croydon Ducati who sold the bike and they do not have it.

Does anyone know anyway to get the map back? My understanding is the maps are already on the ECUs so seems crazy that there's not a way to get it back when it's obvously an error that the ECU has dropped the map, assuming that is the issue.

Also if anyone has any other suggestions please fire away!

Any help much appreciated.

First off: does Display show "racing" upon turning the
ignition on? If that's the case, the slip on upmap should already be installed.

Additionally, check the plug of the exhaust valve servo.
When the termis are installed, you normally install a blank plug into the servo motor plug. I'm not sure wether the upmap itself or this specific plug
turns off the exhaust valve servo and the error message.

But I would definitely check out these 2 options first.

If the display does show "racing" and the blank plug for the servo motor is installed,
it could be a bad electrical connection of the lambda sensors (or maybe a sensor is broken) thus causing the engine light and the jerky ride.

I think it's the "plug" to the servo motor is what disables the check engine light.

I've run with just the plug with and without the upmap and i have no check engine light. Quite a few guys here with Akras and no upmap do not have the CEL on.

As you know this bike vibrates a lot so I'd look around for loose connections, burned wires, or loose equipment.

If you want the stock map back I'll give you my "dongle" and I can have your upmap, with a fee if you like.

Thanks for the replies.

It does not say racing on turn on. I did find the instructions from the termi install and it mentions that, the dealer was not sure. Python; do you have just the slipons and it does say 'racing' on start up? I dont actually remember it ever saying that to be honest, but these problems only started a couple days ago?

The exhaust valve is fully removed, I did check on this earlier and it is correct for just the slipons. The blanking plug is present on the connectors.

if you dash doesn't say Racing or Racing Evo, then you have the stock map.

How long did you have the bike as is until you experienced these symptoms?

I've got all the fairings off and have been through all the wiring/connectors that are visible. At least I've got something to focus on now I suppose but it's not very clear seeing as the exhaust valve has been completely removed. Someone mentioned there may be some water that has got into the blanking connector so I'll check that tonight just in case.

I dont want to put the stock map back on, although the way things are looking I may need to pay for a new UP Map? Surely you cannot get the map key off of my bike if it has 'dropped' it as it seems to have done??

It's been fine until a couple of days ago. I've not had it long but I've done about 1000 miles on it before it started playing up this weekend.

Well, if the up-map key would have been installed, it would have definitely showed "racing" upon startup (respectively "racing evo" if you had the up map for the full system).

Now, to get to the bottom of this, there might be another option which might have happened.
You're saying you never had "racing" showing up on the display, but the error light didn't come on until a couple of days ago.

Also, you apparently bought the bike used if I understand correctly.

Now, if the owner of the bike before you had the bike rexxered with the appropriate map (termignoni slip ons, turn servo valve off and deactivate the lambda sensors), you would not get the "racing" displayed upon startup, but the check engine light wouldn't come on as the exhaust flapper has been deactivated due to the rexxer map.

Now, have you been to a service with your bike lately? If thats the case, and the dealer would have done an ecu update on the bike, it would have overwritten the rexxer map. Since the termignoni up map was not installed beforehand, the software would have just recognized the normal oem map on the bike.

Now, the update of the ecu would have overwritten the rexxer flash, thus reactivating the exhaust flapper servo motor. since its not plugged in, you would now get the check engine light. and since the lambda sensors should have been disconnected during the rexxer flash, the bike is now getting false readings from the lambdas....or in this case, no readings at all since they're not plugged in (also causing an error light).

Try to check if the connections of the lambda sensors are plugged in... maybe this will get us a little closer to a solution.

Excuse my ignorance but what do you mean by 'rexxered' and why would it not have racing show up?

It was bought second hand, and I have had a few nasty surprises despite being in touch with the previous owner who seemed trustworthy at first. The bike has been into the dealers for work recently as the bolts inside the clutch cover rattled loose and killed the clutch basket (big bill, long story, not fun), and it was plugged in for any updates and service at the time. But I've done a track day and several hundred miles since then so would have expected any issues to show straight away.

rexxer is a tuning company which writes maps for bikes.
Its basically just like a power commander but without the extra dongle which has to be connected to the bike. the rexxer map is directly uploaded into the ecu, without the need of an additional tuning dongle.

Now, apart from the fact that you should get your bike "rexxered" anyway (I did it 2 weeks ago, and its the best thing that ever happened to the bike (smoother throttle response, no jerky throttle in low rpms...)), it would maybe be the solution why your bike is now displaying the error message , but hasn't before..and has never had the "racing" displayed upon startup.

All the maps that exist from ducati (the normal map with oem cans, and even the up maps for the termignoni slip on system or full system) have to comply with certain exhaust restriction laws. That's why even an up map key for a termignoni system will never be a 100% perfect....its always gonna be a compromise.

The rexxer maps do not comply to the exhaust restriction laws (officially such a map is not allowed by law and you're not allowed to ride the bike on the street anymore....officially )

The only downside to the rexxer map is, you will need to get your oem map flashed back onto the bike when you need to get your bike thru the exhaust emission test, as it would not pass if the rexxer map is on the bike.
The second downside is, as mentioned before, your dealer should not hook up the computer to your bike and do a map update. This update would erase the rexxer flash and would upload the oem ducati map back onto the bike.

Thanks, did some searches to read about it. The bike only has 3500miles on it and I'm fairly sure the previous owner hasn't done something so involved. The original dealer fitted the termis when they sold it to him new. I've been in touch with that dealer to try and get the map key but they don't have it, they are hopefully speaking with Ducati and coming back with any possible options tomorrow although my earlier dealings with them were not particularly great so not sure if they'll come back with much.

Okay, been out in the garage tonight trying to get some clarity on this.

Yesterday when I put the bike to bed (with the engine warning alarm on from the ride) I did some continuity/short circuit checks on the blanked off exhaust valve plug as that was where the diagnostics were showing errors. I was getting continuity between several of the pins.

I did some proper testing tonight in the hope I could trace a problem in the loom. It turns out the short circuit might be on the BBS box rather than in the loom. But tonight because the bike is cold, rather than getting full continuity like last night, I am getting a resistance reading, which I assume turns into the full blown error and continuity when the bike warms up. Unfotunately I don't have time to put everything back together and ride the bike and then test again so will have to try tomorrow.

I noted the readings from the exhaust valve connector, and tried with the multimeter terminals each way as the readings vary. numbers signify ohms.

Sorry it isn't so clear, the forum software seems to change the table, but can anyone shed any light on these? Looking at the electrical diagram, I don't think I should be getting anything between these connections but not sure?

There has been a couple of posts here on faulty BBS modules. It happens mainly on bikes with full system termis and they forget to install the reflective wrap under the BBS (which is close to the exhaust) module. Include that on your checks also.

Maybe the guy you bought it from had the full system and he took the header and the up-map off?

Cheers, I bought another BBS unit off ebay so maybe that will help, although it did seem a little cheap so a bit concerned about that despite him saying it was in good condition!

I dont have full Termis and pretty sure the last guy didn't ever have them but I'll look to put something under the BBS all the same.

I enjoy working on the bike but we've got a 3000 mile trip to italy coming up and this is not good news!

The BBS marries to the bike once installed and can only be used on that bike. That is what the dealer told me when they replaced mine to find a problem. Said that it would make a good boat anchor once used.

Sh*t, thats a spanner in the works, although sounds a bit suspect and I've heard a lot of rubbish from various dealers lately. Can anyone confirm this??

My bike had a problem and they thought it was the BBS. Dealer had to call Corporate and get conformation before he could change as it marries to the bike and he did not want to have to buy it if it did not work.

Oh yea, it was not the BBS that was causing the problem but a short in the wiring harness that connects to BBS. When they moved it around to work on BBS it would start to work. When you drove the bike it worked that is until you hit a bump and then it would start acting up. Seems the wiring harness, that goes to BBS, on the back side comes close to something sharp as it comes around the frame and can wear through and short.

Might check out the wiring harness.

Can you elaborate on which part of the harness Brickcues? Do you mean where it goes under the petrol tank? This was the part I was checking the other day but I was only getting shorts when the BBS was connected, hence why I suspect the BBS itself.

I guess it's possible that the short is coming from the other side of the BBS where it goes back into the main ECU???

I just know what I was told that it was the wiring harness that plugs into BBS unit. They tried to order another harness but Ducati only had the harness for the non ABS bike in stock so the tech took the harness apart and found the short and fixed and then put it back together. He said you could not see where the short was as it was in back of the harness around a bolt that had a sharp edge.
