Default Mass Air Flow sensor high input

Hello
I am getting this code for Mass air flow sensor high input. It throws the code around 6500 rpms . Usually associated with this is either a fuel cut or spark cut not sure which it seams the car hits a rev limiter. I am running a t3 super 60 on a 2001 EMU. not sure what to think of this. Should I just modify the airflow output adjustment map at the specified rpm? anybody had a similar problem? any help is appreciated. thank

sounds like your maxing out your Maf sensor.
do a data log and see what your maf voltage is when it cuts out.

I remember some NB owners having this issue with high boost.

try using your airflow adjust map to pull back your maf reading voltage. then add fuel back in using the injector function.

No you wont need a bigger afm.

Just trick your stock ecu by reducing your MAF voltage to it.

then add more fuel in using the injector function.

by using the afm table you can stop the the voltage from going above 4.92. on the emanage blue its called "boost limiter cut setting" (its in the parameter setting window) and you can set it just below where you are cutting out.

for example you can stop the voltage from going over 4.85 volts but this means that it may run lean over that. so you need to add in fuel to compensate.
