Can you get some help w your English to explain your problems? All translators I`ve used has been horrible when it comes to detailed descriptions.

I solved the problem of pressure and I changed the type of air temperature sensor and now everything is ok. the problem is always that of the spark plug I do not understand why I can not change the page parameters "Adjust map. " I wanted to change "throttle range" but you can not, why?

The problem is the pick-up.
The pick-up of the Hypermotard is different. I spoke with a mechanic and he told me that these new ones are less sensitive.
Cliff, what should I change to give more input sensitivity of Myecu?
Thanks.

p.s. this is the namber bosch of pick-up: 281 002 191

Also is the pickup over the same type of wheel.

Posts: 21 Arezzo - Italy Gender:	Re: Problem with starting engine Reply #24 - 04/05/11 at 08:02:41 I can not reduce the distance because there are no spacers. The wheel is like any other, as I said with IAW 1.6 everything worked properly. I can not replace the sensor because the "old" ducati st2 is much longer ...

We really need to see how short of the mark the signal is before we can figure out the best way forward. I don't think there is much we can do to boost the signal in the My16M.

Posts: 21 Arezzo - Italy Gender:	Re: Problem with starting engine Reply #26 - 04/16/11 at 00:13:36 I did these tests: I did a thickness sensor st2 and I mounted that, but the controller still does not. I think the problem is the location. st2 sensor sees the gear teeth to the side, and sees the big teeth. Hypermotard sensor sees the gear teeth from above, and sees only the tip of the teeth. I hope it was clear

I'm sorry to be unclear. The wheel is the same as all the ducats, equal to Ducati ST2. the difference is the place to read the pick-up.
View Photos 1.
This is the position of reading ducati st2.
In the picture 2 is the reading position of the Hypermotard.
The positions are different but the wheel and 'always the same .....

I can not enter the picture, you send them by e-mail

Ok understood.

Then it seems most likely that its the signal level from the sensor.
You said this was a different type of pickup
Is there a possibility of getting one like that used by the ducatis or guzzis.

The voltage level increases with engine speed.
If we can get it spinning fast enough.
For test purposes
Try warming the bike thoroughly with the other ECU and have the battery on a charger.

You could also try clutch starting
