Power cut off on citroein berlingo

[finga]

Hello,
I have just changed my 1,6HDI motor by a simple diesel motor here in the foto
86064

And i have changed siemens ecu by LUCAS one
86065
86066

Now the new motor turn on well, but the problem is that power cut off after a few minutes, no thing work on the dashbord, lights also stop working, and the motor continues to work well !!
Any idea ??

I would say there is a problem with BSI which can't recognize engine speed and car goes in to economy mode.
Does rev counter works on the dashboard? Is there message "Economy mode active" on display?
Needs to compare wiring diagrams for both systems and check what isn't connected or what's connected wrong.
Regards
