Hi Guys,
due to multiple pains on 2.2 HDI 4HX engine on 406, we removed and put a RHZ 2.0 DW10TED engine which is more reliable, the problem, is that the turbos are not the same, 136 oneis TGV, the 110 is not, so the RCO of boost pressure control is not suitable, and we have no boost, so, I read ecu flash, removed FAP, and always same problem.
I wonder if there is a good flash that can lead the valve correctly. I have tried 110 hp ecu pulled from 307, and the problem is limp mode, and the coolant gauge not working.
Here is Fapless file from 136 hp ecu.
