HKS VPC... it can convert things to speed density...its what it is for...if you can find one...they were discontinued
The HKS VPC is designed to physically and electronically replace OE air metering devices which present a significant restriction to the Intake
system and offer no adjustment or reprogramming options to take advantage of dramatically higher air flow or larger fuel injectors. The VPC converts both air flow meter and air mass sensor systems to what is referred to as speed density systems by utilizing a 16 bit central processing unit reading its own Intake
air temperature sensor and absolute pressure transducer (B-MAP sensor) signals. This unique conversion feature not only allows the VPC to replace the factory air flow metering device, but also eliminates the need for a fuel cut defencer. Another benefit of the VPC is the ability to create our own programs to take advantage of larger fuel injectors and new air flow characteristics (larger turbos). In some specific instances, the VPC may be used in addition to the PFC F-Con and larger injectors for the ultimate in HKS plug-in fuel system technology. VPC equipped vehicles respond quicker with improved horsepower. Controls those monster injectors as well!
Make sure you choose the right VPC for your set-up. ROM burning $89.00 each for a change to the VPC ROM.
