as they are a mafless ecu how or what does it use to monitor or measure the airflow in to the engine?

The system uses a MAP sensor (Manifold Absolute Pressure) this determines the Air Pressure within the Inlet Manifold. this is where the Simtek gets its measurements.

oh yes and i cant wait for mine to be fitted complete with launch control and anti chav lol

scoobyboy

does it monitor air temp as well then?

Yes an ACT sensor is fitted. Mine is in my intercooler pipe just before the Throttle Body

scoobyboy

is the act sensor plumbed in to the original maf sensor plug wiring or does it plug directly in to the new ecu?

Yes it connects to the original MAF wiring.

scoobyboy

can you think why someone would leave this sensor out of the airflow into the engine and leave it up behind the drivers strut but still wired up to the maf plug?

surely all it's doing is measuring under bonnet temps and not the correct air temp going in to the engine?

Seems a bit strange - maybe they forgot to put it in or they could tap the intercooler or pipework for the sensor so left it for you to do.
