Hello !
One of the BASIC ECU engine protection functions of the BOSCH ME9 ECU that is used in the Camaro LLT is to run the engine in safe mode when the AFM (MAF) is maxed out for longer then 0.1sec
In the safe mode the ECU is pulling the ignition advance away and mostely closes the trottle body to a low value to protect the engine !
NOBODY should change that basic funcion because of wrong or
inapplicable hardware design of the AFM system !
Only way from the engeneering side is to install a propper designed AFM (MAF) housing of 100mm (4") diameter , that the AFM (MAF) Sensor is NEVER maxed out even at lowest altitude and lowest ambient temperatures at full load with max boost in use with with low backpressure exhaust systems !
Hopefully could clear the situation friendly wise with true technical explanations !
