MAP sensor failure or software bug?
Posted: Mon Jun 09, 2014 12:49 pm
Hello,
I've attached a log file from a customer's FN2.
The calibration (AFM enabled MAP based fuel) is NOT TUNED. Is the first log i told him to send me.
MAP sensor reads more than 150 kPa at WOT (car is naturally aspirated) and ECU seems to be applying boost ignition,fuel and WOT lambda adjustment columns causing severe overfuelling, ignition retard and not changing to open loop.
At key ON, engine not running, MAP sensor seems to be working as it should as it reads barometric pressure.
Can you take a look and tell me if could be a software bug before telling me customer to change MAP sensor?
Thanks in advance.
Best regards.
Jose
