Thank you very much, but this car is difficult to start the firmware. If you swap the maps to the address 6c64a 6c72c and then runs perfectly! What's this? Unit from another car?

Car came to repairs.Compaint - low maximum speed - 130 km.Check mark,wiring, temperature sensors and phasing sesor.In temperature sensor circuit was discovered additional resistor 3.3 kilom, after its removal machine start is bad.Read firmware, compared with the same on the other car, differed only cards addresses 6c64a 6c72c.Remove maps in the original firmware.Start is good.

yes,
the mechanich knew that cold start is ok, but hot start not.
So he fooled the temp sensor...that ecu thinks that the engine is still cold - foolish thing to do.

The only proper way is to repair hot start area in cranking map.
