R7 CP2 engine blown help

[youngmaavin 6]

To provide an update, with the help of Michael, we compared the maps from my ECU to the stock one and ignition advance seems to not be an issue and cause for the engine failure.

Tomorrow I will get the bike to a Yamaha dealership and try to apply for a claim.

From everything I've read on the internet, once the map is flashed back to stock, there's no way to tell the ECU has been flashed.

I'm worried about them seeing the signs that something was taken apart and put back together though, like screws, etc. and denying the warranty on that basis.

Thanks to everyone in this thread for providing me with helpful information.

I don't think they can to that.  There's a law that makes them allow vehicle owners to do their own maintenance without voiding the warranty.

From the site below, "You can service your own vehicle without affecting the warranty on it. Under the Magnuson-Moss Warranty Act, it is against federal law for car dealers or warranty providers to deny a claim or void a warranty because vehicle maintenance was performed by the owner.

The only way you can have coverage denied or your warranty voided from servicing your own car is if you perform the service incorrectly."

Just don't say something like "I messed with the map without knowing what I was doing" if they ask why the screws look like they've been removed.

OP is in Israel, I believe. Perhaps it has a law like Magnuson-Moss.

Oh yes... I see that now, thanks.  It does  help to have at least an approximate location in one's profile.

Did you pull the plugs yet and look inside with Endoscope - or are you hoping to keep that "virgin" appearance?

The favorable thing for you is the low mileage. My only advice is to say as little as possible, don't get all chatty with them. Decide on a short, 2 sentence description and just repeat that when questioned.

Yes, that's the plan.

I'm not touching anything else, until the dealership looks at it.

So I want to provide an update for this.

Went to the garage where they confirmed cylinder number 1 is dead.

Read the ECU with OBD and the errors are quite confusing to me, maybe someone can shed light on this?

Before opening an engine further, they suggested to try and go through warranty.

So I went to my tuner and he put back the stock map, that was on the bike and then I cleared the ECU codes as well.

Tuner insists it couldn't be advanced ignition, since he used "stock unrestricted map" and only tuned the fuel, didn't touch the ignition.

Can anyone speculate if it's possible with the stock map back on and ECU codes cleared to see that the bike was tuned and deny warranty?

Very interesting that the lean angle sensor is on that list. Tried to Google that event 203 with no success. That code could mean the bike has been dropped or the sensor is just unplugged or located incorrectly. 

 

With so many sensor codes at once, any chance you had the bike powered up while you were working on it and the ECU just had a moment to realize all those things were unplugged and it's never been cleared of those codes since then?

Have you checked the coolant level?  Has the fan been working as it should? 

Others have mentioned about tapping/detonation if the ignition timing is off. This is true, however you also mentioned overheating. It takes a long time under throttle with detonation to get to the point of overheating, but overheating an engine will cause it to detonate more easily. Soft seizing an overheated engine could easily pinch a piston, causing a ring to break which would lead to oil control issues like you see. 

Until the cylinder is inspected, or at least the plugs, it is a guessing game on what may have happened.

Those codes are gibberish as far as I can tell.

They include sensors, that were never even touched, like lean angle one, that's on the back of the bike I think.

Bike was never dropped, also I'm 99.9% sure I didn't turn the ignition on during the time something was unplugged.

There's also a mysterious CAN communication error.

I honestly don't know what to make of this and I didn't have a chance to check when those codes initially appeared before they were cleared.

Coolant is there, fan was working fine, even lowered the coming on point by a few degrees.

I don't think I've mentioned overheating in this thread, I didn't let the bike overheat really.

Never rode, when the temps were above 100 decrees Celsius.

Yes, at this point I'm stumped as well.

I took the bike to the dealer today and they told me it will take at least 3 weeks before they could even start to inspect it.

They suggested trying to find a licensed garage that works with them if I want to expedite the process.

I've already spent about 350$ just towing this thing around, loosing so much sleep over the situation...

My mistake then. I thought I read that the bike got hot at some point.
