CAJ Innovations Forums - Problem with starting engine

Ducst4 YaBB Newbies Offline I love MyECU! Posts: 21 Arezzo - Italy Gender:	Problem with starting engine 03/15/11 at 04:06:13 I installed my15m in my prototype with engine Ducati Hypermotard. The starter motor of the Hypermotard is different from other engines Ducati, the engine run much more slowly. I have seen my15m no spark on the spark plug, the problem may be that the engine is running too slowly? Thanks

I suggest loading the map I sent you with the ECU until you get the bike started and keep the bike on the charger. Also make sure you use the ECUController that I sent you at the time and not the one you use for the MyP8

If you thoroughly warm the bike with the OEM ECU then try mine then I can't see how the starting will be too slow. You should compare the schematics on the 2 to see if there are any differences that may explain it. Different pin outs?

1. Makes sense since ST2 has a WM 1.6.
2. A bit puzzled, doesn`t HM have a 5.9?

Have you made a custom wiring?

Do the 1100 engine have same sensors f RPM & engine position?

Do you have HM throttlebodies & injectors?
Injectors are different from ST2.
What is the pressure from your fuel pump regulator?

I have a 907 w MyP8.

The engine has a u-pick only.
The injection is a Ducati 916, but the connectors are the same.
The fuel pressure at the moment is standard 3 bar.
For the moment the only problem is that the potentiometer is the same as the Paso and is not intended for My16m. But my problem is that it does spark.

I have already mounted this engine on his Ducati SS wife. ST2 simplified electrical system and ECU 16m.
On my bike I want to use My16m.

I am sorry not to be very clear but I use a translator

I asked if I have your program myp8 for testing in my Cagiva Elefant 900

I checked the values.
The pressure is not correct.
The oil temperature and the air temperature when the bike is cold are not equal, there is much difference.
Looking at the computer, I see half-throttle the cursor is already in the fully open position.
Is possible that the Ducati sensors I use are different?

But it is curious that with all these problems my part ST2 safely

The throttle value can look weird when trying it with engine off, because of throttle pump emulation. But the temps should be within a couple of degrees if actual temp is the same. How much do they differ? What does the pressure read?

Here's a thread about pressure sensor:
