Double trouble in Lima.

I have been Following this ride report closely too and i'm very pleased those two will be able to get back on the road after quite a fatal engine problem, which was caused by poor fuel.....all the computer/sensors in modern day engines and it can't say no to poor fuel....hmmmm

What would you want the ECU to do if it had a built in computer and Mass Spectrometer to detect poor fuel?

By "saying no" would you want the bike to refuse to start and run?

I was just pointing out that something so simple as not having good quality fuel can cause so much damage to the internals of the engine, and with all the sensors/ecu's ect in modern engine's a little bit of fluid can cause alot of trouble for these folks

As I believe these engines have "knock sensors" which result in the ECU retarding the timing it isn't too much to expect a message on the display to inform that "fuel is so poor that damage will ensue if use continues" when the ECU gets to the limit of its parameters and still has a signal from the knock sensor.

Edit, seems I have been misinformed, no anti-knock sensor on these engines. I'm surprised as they are so fuel efficient they must lean towards the lean side of the mixture ratio where knocking is an issue.

Does the 800 have a knock sensor?

I don't think you need electronics to tell you when the fuel is that bad.

I don't think the 800 has a knock sensor, unlike the 1200.

The only problem now, is that these bikes have to get back! They're still in the region of poor quality fuel. Are they going to do any further damage before they get home?

It would be a real shame to rebuild the engines, and find they are damaged again when they get home.

Good point.....! What happens if they fill up with a bucket of the same sh*tty fuel somewhere along the road?

FP.

Any further news? I've read the adv thread up to date, and they're waiting for their engines to be rebuilt. Should have been done by now? I'm surprised that BMW are repairing rather than replace, I'd expect them to want the original engines back in Germany for inspection?
