The manufactures of the chip have calculated the fuel mapping with the extra air from the DV in there on the fuel plots. The car is using that extra air and also adding extra fuel to match it. The A/F ratio is determined by the chip. There is simply not just "more air" being thrown in.

 

Sorry sfordeso, my post was not to you, we posted at the same time and you beat me.

 

what about a CAI? or even an upgraded turbo?

 

Ahh yes, but everyone thinks both of those are factory! They serve a purpose.

 

lol. s'alright man. i just realized that and edited

 

The ECU will adjust as well as it can. The MAF will sense an increase in air, and the ECU will increase the amount of fuel to correct the A/F ratio. There comes a point when the injectors can not keep up though. That's why people upgrade those. If you just throw in a larger turbo, you really won't get any performance out of it, without the software.

 

Actully jesty the ecu will adjust to the bov releasing the air, it will sense and make the the changes. I dont think enough to make a HUGE dif but the ecu will learn.

 

the ecu is smart thats how it was built. yes it takes time (like 2 months) but it wont cause enough damge to destroy o2 sensors or foul the plugs unless the plugs and o2 sensor were getting close to needing replaceing.

 

Umm the MAF samples the air volume. The DV dumps its air into the intake track AFTER the MAF has already taken its readings. It has already calculated the according fuel plot.

 

i know the maf takes its readings. the info is sent to the computer then the dv dumps the air. the air that is not picked up by the maf. so all the extra air does is lean out the mxture a little bit
