boost referenced rising rate fuel pressure regulator
Hey guys,
So in my quest for cheap boost enrichment, I came across these. Cartech has the latest and greatest, just wondering if any of you have experience with this:

Oh, and you haters really need to stop bashing. This is your absolute final last chance. If you can't help, then at least stop bashing.

They work well for stock cars with small boost.
The problem is you end up fighting the fuel pump, and eventually the solenoids on the injectors.

Re: boost referenced rising rate fuel pressure regulator
yup way outdated and damn near the cost of an basic ms system or chip burning equipment , actually its still cheaper to go get tuning software + the chip burning equipment , or an ms system or ebl
after u pay nearly 270+ shipping for an fmu , then the 50$ or so in lines and adapters u need to hook it up u still need some way to retard ignition timing from stock , which then u either need a programable msd box or btm or something similar which is about 250-400$

Re: boost referenced rising rate fuel pressure regulator
Cheap and boost, two words that cant be used in the same sentence.
Buy a megasquirt system to assemble. The amount of time you would spend installing, trying to tune, and still not getting the result you desire would be better spent on something you know will work. Who is to say that the fueling at a few pounds of boost will the whats needed at 10 or 15 - on top of that timing needs to be pulled. Buy a MS unit set up for boost (or build one) and do it the right way unless you like buying engines over and over.

Re: boost referenced rising rate fuel pressure regulator
FMU's are sketchy at best. I used one when I first went turbo years and years ago. WOT was ok at low boost (5-6lbs) but any boost during part throttle driving and it would go way lean. So basically I had to stay out of boost unless I was WOT. Not ideal for a street driven car. I went with the code $58 and its night and day. I wouldn't bother with an fmu. Just my .02 cents
