alpha-n is just the name of the type of management they're doing.
ahhh... thats exactly what i was looking for.. thanks... im no expert but i understand what you mean... my BMW is on a MAF system, and I kept thinkin of the actual sensor that sits in the air stream as the above mentioned "component"... yes i understand the simplicity of alpha - n... see, the M3 CSL, sold in europe as a street car, employ's an Alpha-N based ECU... (cause the car is ususally used by race teams for the DTM race circuits) and i was trying to understand how it works... i guess BMW gave the tuners of that car an easy access point (the alpha-n based ECU) to easily tune the car for racing from the getgo... makes sense..
so if i buy an AEM or TEC3 for a honda, it can be configured it to run in alpha-n mode if i want to for a race setup... or it can be configured for MAF or MAP mode (with all sensors) if im looking for a street setup right?
thanks for the info...
