Two years ago   there was a defect  59MA  Ecu on my 998 Duc I have replace this device with a used one and  extend both  connectors  until the seat .

I assumed the defect was caused by the motor temperature, 

Last week  I got problems and the injectors was not working .  with  the  JPDIAG  test function  the injectors was working well.  

Dismounting the  crank shaft sensor  and putting some metal to the sensor was  let  the injectors  working.  

I assumed it is the Sensor and I have replace it.    The new one was not working as well.    and the signal on the Oscilloscope  was on both the same .
The signal was perfect.  So I guess it is the  ECU  sensor  interface.  

I never got problems  with ecus before but is it possible there  is a general problem with this   IAW59 Ecu ?   

Is it possible  to use another newer one?  are someone  in the Forum  with  similar problems?

Cheers

Katanajones aka Armin

usually they become defect on the coil driver
double check the grounding of your ecu , it may works badly if it's not powered enough

hmm ok , it seems it's not a dust issue
if you test injector with jpdiag and can see it spraying , then ecu looks fine
maybe your fuel pump has not enough pressure ?

Yes   Spark and injectors are working with the test button.   I'm  working now  on a simulator  to test all on my desk.

i have used a new one with the same result.   the signal on the oscilloscope is perfect  and i have tested  the wire  from the sensor plug until the ecu plug  but i never  test the signal on   the  ecu   plug    ( Engine 25/35  )

Finally, I found the problem .  recently I have moved the ECu under the seat.    The problem  start  caused by an defect cram shaft sensor, during my investigation  I have rewire the  sensor  from   old ecu position until the seat position.  on the engine  ( black ) ecu plug (  i have use ecu plugs  from a Fiat car )  there was already a shield cable on pin 25 / 35 with a red / black cable.   I have   connect the red  to +  and the black to -   .   In fact that was wrong and the sensor start with a negative   sinus wave  . after changing the polarity all was working perfectly !!!!
During my test I use the oscilloscope direct on the sensor  and have checked   only the wire connectivity  Sad  but never   from sensor plug until the ecu plug using the  wiring drawing -

I write this long info because it can be other people can have the same problem :-)
