Hi,
just did an engine swap, OM646 diesels both of them, but the new one has smaller fuelpump and nozzles, the 136hp version. Old one had 150hp i believe.
As expected the car doesn't start until it gets an ok reading from the fuelrail pressure sensor, so I need to either program the value of new sensor into the ecu, or play around with the sensor itself to give correct amount of voltage.
Anyone done this before?
