W205 New engine installed M654

Hello,

I installed on W205 new engine M654
The original is 1600 and what I installed is 2000
Xentry showing now "Air mass sensor" fault

What could be the problem to be solved ?

Thanks!

Drive the car, if seems to be working without issues and the power as should be, then read maps, send me fault code to remove DTC
Other way, try to flash and code the engine ECU from a donor car that has the same engine (2000)
Last thing, following xentry steps and actual values, what are the results?

Best regards,

Thanks for your answer,
Flash and code should be done by Vediamo ? Do you have instrcuions for how to do ?

With Xentey or If you have a good scanner, you can code what engine you are using, try that first. Or buy a ecu for that engine and read the maps and flash them to your actual ecu... another thing would be to tune your ecu for new values
