MPPS Checksum question
#1
Hi Guys,
So I have flashed a car with a file I got from a relatively big remapping company. 
In file name was mentioned Checksum fixed. 

I wrote the file in ECU with MPPS. 
Usually I have to press the checksum button, this is also what MPPS asked me to do.
But in this case I did not press the checksum button as the checksum was fixed already.

We flash went wel, but I had the feeling it skipped some parts.
Now car is driving very rough, not nice at all. Very strange turbo action on it.

File attached. 

My question is, can this be caused by not pressing the checksum button?

Thanks in advance.

Write The file on the car and test it, if for you is good, live it the way that It's.
