The HKS VPC is a fuel management device that is designed to physically and electronically replace the OEM air metering devices for improved air flow and precise fuel delivery control. OEM air metering devices, such as Air Flow Meters (Flapper/Plunger types) and Air Mass Sensors (Hot wire / Karmen Vortex types) measure the amount of air flowing into the intake manifold in order to properly control fuel enrichment levels. Aside from offering no adjustment or reprogramming options to take advantage of dramatically higher amounts of airflow or larger fuel injectors, the OEM air meter also represents a significant restriction to the intake system. To overcome this restriction, the VPC physically removes the OEM air meter to dramatically improve airflow capacity and converts the system to what is referred to as a speed density system. By utilizing a 16-bit central processing unit, the VPC reads it’s own intake air temperature sensor and absolute pressure transducer (B-MAP sensor) signals and then converts those signals to one that is recognizable by the factory ECU. The VPC also incorporates the ability to upgrade the internal application specific ROM program to correctly compensate and take full advantage of larger, Higher flowing, HKS fuel injectors and/or the greater air flow characteristics of larger turbos. Each application specific ROM program is calibrated for a specific injector size, fuel pumps, camshafts, and/or turbos, ensuring that the correct injector pulse width is calculated to prevent driveability and reliability problems. Since the VPC “piggy-backs” the factory ECU, all factory systems are still intact and operational. Fine tuning of fuel curves can be further achieved by integrating the plug-in GCC or by wiring in a Super AFR.



So is this stuff actually work? OR would it work on Lancers?
I have seen a lot of supra guys using it and no complains so far. The item is discontinued but still available.

Never heard of it

After looking up more information about this product the conlcusion is, NOT WORTH IT.
It costs about $1k or $500 on ebay and there seem to be problems with the idle, gurgling?, minimal hp increase. Standalone would probably do better than HKS Vein Pressure Converter.

its not for the evo....

^Why not? Karmen Mass Air right?

you would be better off buying some other piggyback. either the greddy emanage, apex'i safc2, RRM/SplitSecond PB, there are many other options that you might want to look at, that will save you money, and also, from what i understand, give you better gains.

I think the point is he wants to replace the MAF with MAP. Maybe I'm just reading too much into this though. E-manage should be able to do it with a pressure sensor harness though.

^What Andrew said. I will look into E-Manage.
