Re: High Flow MAF revisited - (Porsche 928 voltage MAF)



I'm just nuts enough to be game, but I'm not sold on the reliability of a
Bosch sensor... I'd much rather have a
LT1/LS1 style MAF- seem to be more reliable, and cheaper...
Like ya said, $300 is a lotta clams for a USED part that would probably
work, but ya never know...
I want to do something, but I have lots of time- car will not be on the road
until march/April at the earliest though... Just bought SuperRam, BBK TB,
Flowmaster exhaust, and will be buying AFR 190's, a ZZ4 cam, and SLP 1.75 SS
headers for it...
BTW, looked at the Ideas for Design F/V circuit,but I'm no EE- does anyone
have a circuit that would take 1250-11216 Hz, and turn it into 0-5v?
