Get rid of that MAF
Anyone tried something along these lines?
MAF's seem to be a problem especially later cars, any thoughts?
I quite like the idea of this and might be able to get one, any comments?, worth a try?
JDM HKS VPC VEIN PRESSURE CONVERTER - F-CON
To quote HKS "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. To take full advantage of the VPC, HKS VPC Power Flow adapters with the HKS Super Mega Flow air filter should be used." end quote.
Picture coming...

hmmm..
might be slightly too advanced electronics for me
..one of the reasons I gave up my degree
Anyway, I've got my eyes peeled on a second hand source that has a couple a week come up in japan.. If I can find enough to read about them and find one with the correct EPROM I might not be able to resist.
Surely you could re-map one Paul?

Andrew is getting me the bits for this. VPC is no longer made and was very expensive and used a custom EEPROM for each car.
If the thing I'm building is of any use (or not as the case may be) I will of course as always share the results, and undoubtedly the circuit and the code as well.
