I am working on a prototype (read:cheap) CAI for my 97 V6 MT. So far I have the stock MAF inside a 3" ABS (that means plastic) pipe. It's sealed to the pipe just like factory intake, then connected to the throttle body. I have plumbed the 3" ABS pipe into the stock airbox for now, to remove the variables of incurring unexpected turbulence over the MAF.
The bad: Now the larger diameter tubing throws off the MAF sensor voltage past what the ECM can recover, so the car won't run too well yet. But it runs. Anyone out there ever modded their MAF sensor to accomodate the reduction in airflow (due to a larger diameter air intake duct)? My reasoning here is as follows: Small (stock) diameter intake=more air velocity over the sensor/large diameter intake tube=lower velocity over the sensor per square inch. I need to compensate for the reduced velocity of air over the sensor. Any (helpful) thoughts are welcome.
