-I check have injector pulsing, have strong spark, fuel pump run does have fuel pressure, replace new spark plugs as well..... i notice when i crank try start the engine the engine crank fine try to catch up to start but the code ' Incorrect data ' still show storage Active in DME

-also i watching the RPM sparely move about 159min/lb mean it's seem not correct flash data calibration file;s from using autohex II down load from server

-my question is there problem wrong flash DME when using autohex II or wrong DME can cause Incorrect data.....?? this car is USA not Euros so may be mean wrong data flash calibration because autohex II server is programming wrong calibration file's.........????????


-what should i do to fix this.......??? programming per istap or what should get another DME to match number size by size......????? customer replace how own.....until i really i found out y is Incorrect Data code storage in DME because all i can see both DME number is not match from MSV80 to MSV80.1 that all i can ask for this foruum to help so i can get this car start.............please help

Incorrect data is a fault comes when you replace a DME that has Internally different configurations of what supposed to be (Power class, EGS type, BUS type,....)
The only way to avoid this is to replace this DME with another one that has same configurations.
This DME is healthy, once you mount it in a the CORRECT car, this fault will disappear.
