The Hyper Curse

Well I had an interesting day. Sold my hyper to a very enthusiastic rider who has had the lust for a Hyper, coming from a 250 supermoto. We negotiated price beforehand. Very straightforward compared to getting haggled in person. A fair bit less than I was asking, but I was tired of looking at it in the garage and feeling guilty.

Rode it to meet him in a public place, he test rode it about 15 minutes and liked it enough to say yes! Off he rode into the distance and I ended the Ducati chapter of my life, to move on to new and exciting things. Or so I thought.

About half an hour later I get a text "What are 'Errors'?". Yep, the dash showed errors with a check engine light. Apparently the bike still runs fine - no limp mode or anything. I have NEVER seen this before, and always considered myself lucky never having an electrical problem on an Italian bike. Why now?

Anyone have any ideas? It's a very odd predicament. I rode it 15,000 miles without an issue and then it screws up the day I sell it? I swear this is some kind of curse. My only thought is maybe the throttle unit, even though I already had it swapped out when the recall came out. Anyone have one go bad twice? I am doing my best to help him diagnose it.

Machines and engines build a memory. Regardless of any 'smart' tech, mechanical entities get used to you. You're paired so it's always the same. As soon as another vibrator gets on, the harmonic changes, and disrupts. The same thing happens when someone drives my '94 del Sol, always acts funny when getting re-normalized to my frequency. My Stihl chainsaw just did it yesterday too. Never have any issues with it until someone else puts their hands on it and poof, it's got issues.

That's effing deep, Ty.

Kuk, the only time I got that was very recently when my bad starter cycled so slow that it booted the ECU. Got the CEL, 'errors' and it reset my gear indicator. Had to be a bad voltage issue because once it finally turned over, it went away. I've also never had the disco ball recall issue.

Bummer man. Maybe it's some cross-dimensional force drawing you two back together. Kids lucky. Couldn't have done business with a more competent non-licensed mechanic.

Sad you're leaving the forum. The TCU thing never resulted in an error on the dash.

Did you do any new work to the bike?
Did the new owner do anything? Sounds unlikely given the time frame but... Maybe he took the seat off and when putting it back on pinched a wire or something like that. Could his boot have loosened a connection?
Did you get the canbus filter put in?

Best of luck on this.

I did read that sometimes the tcu would cause a light. I did have the can filter installed. Didn't do any work to it in months and it was running great.

So he says it runs fine. It will only get the error light after about 5 minutes of riding but it doesn't affect anything. Makes me think it's an emissions related fault code (TPS, O2 sensor, PAIR valve) and not a functional one. I think it might be worth unplugging and re-plugging some connectors and just giving every thing a visual check for something obvious. I wish I had a code reader - did we every come up with a good solution for that? He ran a few tanks of gas through it already, so that's a good sign lol.

Ty, that's a very interesting theory. It sounds superstitious, but I kinda have to agree. Ignoring modern vehicles that quite literally adapt to your riding/driving habits, I do think there's something off when someone else uses my thing. I can distinctly remember my car shifting better every time my dad would drive it. I could never explain this, and as an engineer its super strange to not have a logical reason behind it.

Anyway - thanks for the help guys! I will let you know the outcome.

Yeah I'm a bit far over on the transcendental side, aka hypersensitive (forgive the Millennial Hotword, but it's quite accurate.). Hypermotard. Hyper this and that. The bike is so perfect for me and such a sensual mechanism developed by the Hyper passionate Italians. Any small nuance can throw it out. I've made a magnificent relationship with my bike and only one other person has ridden it, as I rode his white 959 Panigale. I've read a lot about the peculiarities of the bike but haven't found them to be negative but rather a bike to learn from and develop higher skill sets for riding.

Right, regarding your issue, you mention fuel. Maybe he put some bunk gas in. If you always ran the same high octane non-ethanol, and he pours in some Arco, well I can only imagine my bike would be thoroughly irate.

One thing is sure, it's not a coincidence. No such thing. Some thing he's done is different so I'd suggest going over what those things are and give it the old process of elimination.

There is a solution, and I only just recently got the cables to test instead of the hack job I was doing before.

Melcodiag is what I have found to work as a solution. You will need a connector to hook into the CANBUS port, and a good ELM327 adapter.

Unfortunately, finding a good US supplier for both is a bit tricky. I ended up using Lonelec out of the UK.

Any chance it's an O2 sensor? I had a seemingly useless CEL on the dash and the bike rode great, ended up being an 02 sensor.

That would be nice. The thing that confuses me is that the rapid bike is supposed to emulate the o2's. I'm wondering if it's related to that part. I haven't heard of a single one of those breaking but I guess it's not beyond possibility.
