I did a test with the cali.ecu map.

log is in the other section of the forum.

does it look better or worse than the previous attempt?

Thanks,

I'll take a look some time. Unfortunately this is very slow going forward on my part..

It's weird that the log shows RPMs way past 1000rpm, but the engine never ran during the test. Perhaps just one - two coughs of trying to spin faster.. maybe that's what they are.

Video works well.

Don't leave the tablet on the bike. I see a disaster looming.

No firing at all. Maybe there is too much fuel. Does it smell fuelly.
Can you send my the log for verification.

Restore the injvon and try reducing the prime values by 2.

Cliff, can you see in the log file if the pulses from the sensors are arriving similarly to a California? just to be sure the timings are correct.

No, not that I know of?

The reason for me asking about the timings vs. a California is because, I am baffled by the starts.

Even if the fuelings were +/- 50-100% off, I would assume the engine would TRY to start. It would cough, spit, sputter, shoot in the pipe and do all sorts of things.

NOW, all it does is spin, spin, spin. Not a sign of even trying to start.

On the other hand, if the spark is 90 degrees, or 180 degrees wrong, it will definitely not start. That's why I want to know if the pulses are the same in a Ducati and a Guzzi.

Are they supposed to be? I would assume so.

Have you ever actually looked inside a ducati running a P8 computer?

Next thing we will do (after I figure out the running-on-one-cylinder-problem) is hook a strobe light and look for timing marks and sparks and so on, to make sure we are seeing sparks at the correct time.

I'm not yet prepared to send the ECU over, but if that's what it takes, then I will do it at some point.

Oh, and yes; the video and the log are the same instance.

Thanks for all the input so far!

One of the earliest MyP8s went into a Cagiva which has the Ducati engine and there was no timing difference for that.
Occasionally Ducati do something complete different like they did with a variant of the 15M but so far nothing I have seen was different timing wise.

I don't share Rick's opinion about forgetting the cold start for now.
I actually use these values for my V11:

My experience is that a lot of fuel gives good response, firsthand, but then bears the risk of drowning it if you have too many starting attempts. I usually hold the button not longer than 1 or 2 seconds, pause 1 or 2, then press again. It should not take more than 3 goes, otherwise add another unit at the actual temperature (from 20 to 21).
Remember, it's milliseconds. That's about twice of what you have, or maybe only I have that,  at full bore, so changing from 20 to 22 is a huge step. Also worth remebering is the fact, that as long as he RPMs are below the first column the fuel is controlled only by this single line.

BTW: a 750 Breva ecu or one from a 800cc Ducati starts (and idles) the 1100cc engine perfectly, so with your bike the above values should work similar.
